SNAP RING PLIERS

What are retaining ring pliers?

Retaining ring pliers are specialized tools used to install and remove retaining rings including snap rings, housing rings, constant section rings, circlips and more. Plier variations include internal, external, and convertible pliers.

Different types of retaining ring pliers:

Internal - Internal retaining ring pliers are designed to be used with internal retaining rings. Available in straight or 45 degree jaws for easier accessibility to retaining rings. Jaws are tapered inward to fit inside bores and housings.

External - External retaining ring pliers are ideal for installing and removing external retaining rings. Available in straight of 45 degree jaws for easier accessibility to retaining rings. Equipped with fixed stops to prevent overspreading of the external retaining ring during installation or removal. Jaws are tapered outward, easily accommodating shafts.

Convertible - Designed with interchangeable jaws to accommodate internal and external retaining rings.

Ratcheting - Ratcheting snap ring pliers are ideal for large retaining rings up to 10 inches in diameter. The spring loaded ratcheting feature enables the user to expand or compress rings through gradual steps providing more control over installation or removal.

Internal pliers assist installation by compressing the ring for placement in the groove.

External pliers assist installation by expanding the ring to slip over the shaft for placement in the groove.

The ratchet lock works by allowing the pliers to compress/expand by small steps to assist in installation.

What is the difference between internal and external snap ring pliers?

Internal Snap Ring Pliers - The jaws of internal snap ring pliers are tapered inward to compress the snap ring so it may be installed inside housings or bore applications.

External Snap Ring Pliers - Feature outward tapering jaws that allow the snap ring to be expanded to fit over a shaft in external applications

How do you use retaining ring pliers?

1. Wear safety glasses as retaining rings are under pressure during installation and removal.
2. Align the jaws of the pliers to the lugs of the retaining ring.
3. Insert jaw ends into the lugs of the retaining ring.
4. For internal retaining rings, compress the ring with the pliers and remove or install as needed.
5. For external retaining rings, expand the ring with the pliers and remove or install as needed.

Do I need snap ring pliers?

Yes. Snap ring pliers make efficient work of removing and installing retaining rings while significantly reducing the risk of marring the surface of machined parts. It is possible to remove retaining rings by using other tools, however, this can be time consuming and potentially damage machined parts.

Where can I buy snap ring pliers?

Snap rings can be purchased from G.L. Huyett online or by phone! We have a variety of styles to choose from including internal, external, convertible, and ratcheting pliers to fit inch and metric retaining rings.

THREAD REPAIR TOOLS

What is used for thread repair?

There are various methods for repairing threads, ranging from thread taps and dies to external thread repair tools. Depending on the type and location of the threads being repaired, some tools are more suitable than others.

How do you fix damaged threads?

Threads can be fixed using taps, dies, or external thread repair tools. Below are steps for using each tool.

External Thread Repair Tool

1. Since external repair tools reform material rather than remove it, cutting oil is not required.
2. Place the jaws of the external thread repair tool over the work piece.
3. With the adjustment screw, tighten the jaws over the work piece until the cutting blades fit snuggly into the threads of the work piece.
4. Rotate the thread repair tool around the work piece so that the cutting blades are pushed forward, engaging the damaged threads.
5. Continue to push the repair tool around the work piece, tightening as necessary to ensure threads are reformed as desired.

Thread Tap (Internal Thread Repair)

1. Make sure the threads of the tap match the threads needing repaired.
2. Apply a small amount of cutting oil to the damaged threads and the tap.
3. Align the tap along the same plane as the threads and perpendicular to the work surface. Misalignment will cause additional damage to already existing threads.
4. Slowly begin rotating the tap into the hole to engage the threads.
5. Periodically back out the tap to clear accumulated debris.
6. Re‑apply cutting oil as needed.

Die (External Thread Repair)

1. Make sure the threads of the die match the threads needing repaired.
2. Apply a small amount of cutting oil to the damaged threads and the die.
3. Align the die along the same plane as the threads and perpendicular to the work surface. Misalignment will cause additional damage to already existing threads.
4. Slowly begin rotating the die, engaging the threads of the work piece.
5. Periodically back the die off the work piece to clear accumulated debris.
6. Re‑apply cutting oil as needed.

RIVET NUT TOOLS

What is a rivet nut tool?

A rivet nut tool, more commonly known as a rivet nut setter, is a tool used for installing rivet nuts. Rivet nut tools come in many variations, the most common being hand, pneumatic, hydro‑pneumatic, and portable battery operated.

What are the different types of rivet nut tools?

Hand - Hand held rivet nut tools, or rivet nut setters, are offered in a variety of configurations. The most popular include double action lever, double ratchet, hi‑torq, plier, and the rivet nut hand tool. All varieties are ideal for low production environments and prototyping.

Spin‑Spin - This includes pneumatic (air powered) and portable battery powered rivet nut install tools. These are ideal for high production environments and automation.

Spin‑Pull - Hydro‑pneumatic, or air and hydraulic power, rivet nut tools are the most common for this style. Pull to pressure and pull to stroke capabilities allow for repeated, consistent installation of rivet nuts. Ideal for high production environments and automation.

How do you use a rivet nut tool?

Hand Tool

1. Thread the rivet nut onto the mandrel of the preferred hand tool.
2. Action the tool by squeezing the handle or rotating the compression nut depending on the version of tool in use.
3. Continue to action the tool until the rivet nut is compressed and secured to the desired substrate.
4. For ratcheting, Hi‑torq, and standard rivet nut hand tools, loosen the compression nut to break the tool free from the rivet nut.

Spin‑Spin Tool

1. Check manufacturer recommendations for proper operating PSI for pneumatic rivet nut tools.
2. Thread rivet nut onto the mandrel one quarter turn.
3. Insert the rivet nut into the hole of the desired work piece.
4. Depress and hold the forward action of the rivet nut gun trigger until the tool finishes cycling and collapses the rivet nut.
5. After the rivet nut is collapsed, press the back action on the trigger to remove the tool from the rivet nut.

Spin‑Pull Tool

1. Check manufacturer recommendations for proper operating PSI for pneumatic rivet nut tools.
2. Apply pressure to the rivet nut and depress the trigger of the tool to draw the rivet nut against the cone of the gun.
3. Release the trigger and insert the rivet nut into the hole of the desired work piece.
4. Depress and hold the rivet nut gun trigger. The rivet nut gun will action, attaching the rivet nut to the work piece.
5. Continue holding the trigger as the gun finishes cycling, releasing from the installed rivet nut.

How does a rivet nut gun work?

Rivet nut guns have three distinct methods for installing blind thread inserts:

• Spin‑spin
• Spin‑pull to pressure
• Spin‑pull to stroke

Spin‑spin rivet nut guns:

Spin‑spin rivet nut guns use air pressure to spin the chuck, or mandrel, of the gun. As the mandrel spins, it draws the body of the insert in. This action collapses the wall of the rivet nut, securing it to the desired substrate. Once the threaded insert is installed, the mandrel reverses its rotation to separate from the fastener. This style of rivet nut gun requires awareness from the operator as to not over‑tighten the rivet nut.

Spin‑pull to pressure rivet nut guns:

Spin‑pull to pressure rivet nut guns install the fastener based on a pre‑set pressure determined by the operator. The rivet nut is threaded onto the mandrel, which retracts, pulling the threads of the fastener into the parent material until a pre‑determined pressure is achieved. Pull to pressure installation is ideal for parts with variable material thickness.

Spin‑pull to stroke rivet nut guns:

Spin‑pull to stroke rivet nut guns install the fastener based on a pre‑set stroke length determined by the operator. The rivet nut is threaded onto the mandrel, which retracts, pulling the threads of the fastener into the parent material until a pre‑determined stroke is reached. Pull to stroke installation is ideal for parts with a uniform material thickness.

How do you install a rivet nut without a tool?

A very simplistic approach to installing rivet nuts without a rivet nut tool is using a hex nut and bolt with the same threads as the rivet nut needing installed. Thread the hex nut onto the bolt, followed by the rivet nut. Using two wrenches, hold the bolt in place and tighten the hex nut to collapse the rivet nut.

This can be a difficult, time consuming process with varying results. Using the right tool for the right job is always recommended.

RETAINING RING APPLICATORS

What is a retaining ring applicator?

A retaining ring applicator is a simple tool with an integrated handle and a retaining ring seat at the end of a hardened steel shaft to securely hold retaining rings for application. They are ideal for external, radially installed retaining rings and can work in concert with retaining ring dispensers.

How do I use a retaining ring applicator?

1. Position the retaining ring into the applicator seat with the open end of the ring facing away from the tool.
2. Push the retaining ring against the intended shaft until it snaps securely into place.
3. Pull the applicator away from the shaft, leaving the retaining ring installed.

Ring must be securely seated in the groove for proper installation.

Where can I buy a retaining ring applicator?

Retaining rings can be purchased online or by phone from G.L. Huyett. Our retaining ring applicators are crafted from hardened steel and fit both metric and inch retaining rings.

RETAINING RING DISPENSERS

What is a retaining ring dispenser?

Retaining ring dispensers provide a means of storing and dispensing large quantities of retaining rings. They are ideal for large production and automated environments.

How do I use a retaining ring dispenser?

1. Load a stacked roll pack of retaining rings onto the rail of the dispenser. The retaining rings will fit along the rail of the dispenser, positioning them to be removed with an applicator.
2. Using a retaining ring applicator, remove a retaining ring from the bottom of the stack on the dispenser.

GREASE GUNS

What are the different types of grease guns?

There are many different types and designs of grease guns, and we offer lever, pistol, cordless, and pneumatic grease guns. We have a gun for practically any application. G.L. Huyett offers the following on our site.

Lever Gun

Our standard lever gun is not only economical, but also provides the most volume per stroke as compared to other manual guns. A full range of interchangeable / customized features are available to suit your individual needs. ** Lever guns require two hands to operate. **

Pistol-Grip Gun

Pistol-grip grease guns are good for use in close-clearance areas. Using just one hand, grease is pumped via a simple squeeze. Pistol-grip guns typically dispense less grease per stroke than a standard two-handed lever gun.

Cordless Gun

Cordless grease guns use rechargeable Lithium-ion batteries for complete portability and ease of use. Huyett grease guns come equipped with a carrying case and two batteries for extended use. ** Cordless grease guns are trigger operated, portable, and convenient. **

How to attach a grease gun to a zerk fitting

1. First, ensure both the zerk fitting and the grease gun coupler are clean and free of debris and other contaminates. This will help ensure a secure connection between the fitting and the coupler.
2. Next inspect the fitting to ensure there is no damage. If the fitting is damaged, you may want to consider replacing the fitting before continuing.
3. Once everything is clean and inspected, set coupler at an angle to fitting and while firmly pressing down, roll the coupler onto the fitting. You should feel the coupler clamp down on the fitting and click into position.

How to remove a grease gun from a zerk fitting

1. Ensure that the pressure has been relieved between the coupler and the grease fitting.
2. If this does not happen on its own, tilt the grease gun coupler to approximately 15 degrees to break the seal. You may see grease expel from between the coupler and the grease fitting.
3. Once pressure is released, continue tilting the coupler past 15 degrees while at the same time twisting back and forth.
4. This should safely disengage the coupler from the fitting.

How do you bleed air from a grease gun?

For grease guns with a relief valve:

1. Pull the plunger back to the bottom of the grease gun cartridge
2. Press and hold the relief valve at top of the grease gun
3. Action the grease gun pump until grease expels from the coupler
4. Push the plunger back to the top of the grease gun cartridge
5. Action the grease gun pump again until grease flows from the coupler

For grease guns without a relief valve:

1. Pull the plunger back to the bottom of the grease gun cartridge
2. Partially unscrew the cartridge from the grease gun head
3. Rotate the plunger until you are unable to push it back in
4. Action the grease gun pump until grease expels from the coupler
5. Screw the cartridge securely against the grease gun head
6. Push plunger back into the cartridge

Why does my grease gun not work?

• Empty grease gun cartridge – Unscrew the grease gun cartridge and verify that it is still full of grease. If the cartridge is empty, replace it with a full cartridge.
• An air bubble is in the grease gun head – If there is ample grease in the cartridge, follow our steps on how to bleed air from a grease gun.
• Contaminates in grease – Debris in grease such as dirt, gravel, or plastic can clog couplers, pumps, and hoses. Thoroughly clean the grease gun as well as replace the tubes as needed to ensure no contaminates exist.

MULTI TOOLS

What are the different parts of a grease fitting multi tool?

• Socket - The two socket ends of the multi tool fit over straight and angled grease zerks and can be used to tighten or loosen grease fittings.
• Extractor - The extractor can be used when the hex portion of the fitting has been round off or if the head of the fitting has been broken away and a socket or wrench cannot be used to remove the fitting.
• Tap - The tap is an excellent addition to the multi tool that allows the end user to clean out the threads to ensure ease of assembly.

How do I use a grease fitting multi tool?

• Start by using the socket end of the tool to loosen the grease fitting.
• If the socket end does not work or the fitting is broken, loosen the fitting by inserting the extractor bit into the center of the fitting.
• Using the socket or extractor, rotate the multi tool counter clockwise to loosen the fitting.
• Continue to loosen the fitting until it is completely free from the mating component.
• Clean the threads of the mating component with the multi tool's tap.

OIL PUMPS

How does an oil pump work?

Oil pumps dispense fluid from bulk containers to applicators or mechanical components by siphoning lubricants from the reservoir through the pump's outlet. Manual rotary gear, rotary vane, or lever oil pumps, as well as pneumatic wiper pumps, are popular styles that are suitable for low and high volume needs.
