Belleville Washers

Belleville Washers

Belleville washers, also known as conical spring washers or coned-disc springs, are conical shaped metal disks made to handle high loads with limited deflection. Given the curve of its shape and design to meet any locking requirements, Belleville washers can be used in various applications. Belleville washers can also be stacked together in parallel, series, and parallel/series configurations to increase deflection and load tolerances.

  • Available in alloy steel, spring steel, and stainless steel
  • Also available in zinc, phosphate, or plain finishes
  • Maintain high joint tension despite thermal expansion
  • Belleville washers are often used to reduce vibration and relaxation

Curved Washers

Curved Washers

Curved Washers, or crescent washers, apply light pressure to its mating part to resist loosening of machine components caused by vibration. Much like wave washers, curved washers can also be used to distribute loads of threaded bolts, screws, and nuts evenly. In addition, the inside diameter of a curved washer can be adapted to a specific load/deflection function.

  • Available in spring steel and stainless steel
  • Often used to absorb axial end play
  • Provides a uniform spring rate and load distribution
  • Reusable for general applications
  • Ensure that the uninstalled height is in tolerance for more precise applications

Disc‑Lock® Washers

Disc-Lock Washers

Disc-Lock washers by Sherex, also called wedge lock washers, are single‑use, heavy‑duty, self‑locking washers composed of a pair of washers featuring cams on one side and non‑slip ridges on the other. During installation, the washer is installed between a fastener and a work piece. When the fastener is exposed to load, vibration, or shock, it attempts to loosen. Any movement in the loosening direction is forced to the washer assembly creating a wedge effect that prevents the fastener from rotating loose.

  • Vibration proof according to MIL‑STD‑1312‑7
  • Preassembled for easy installation
  • Installed using common hand tools
  • Intended for permanent joint fastening
  • Fastener does not need re‑tightening after installation

Fender Washers

Fender Washers

Fender washers are flat washers with an outer diameter that is three times as wide as the diameter of the inner hole. These flat, broad washers are often thinner than other washers allowing them to better contour to uneven surfaces and provide more surface area to spread the force of a heavy load. They are commonly used in auto‑body restoration or other sheet metal applications as well as in plumbing and electrical applications. Because of their robust durability, they are also present in applications using sheet rock (gypsum board) and wood.

  • Available in spring steel material in plain or zinc finishes
  • Prevents gauging from fastened materials when placed underneath a head
  • Wide diameter provides increased load distribution
  • Installed using common hand tools

Finger Washers

Finger Washers

Finger spring washers, or finger disc springs, are a spring steel washer with bent tangs around the circumference of the washer that provide additional spring like qualities. Finger spring washers reduce skidding on rotating elements making them ideal for ball bearings and other rotating assemblies. Finger spring washes do not widen under compression, making them ideal for housings with little clearance.

  • Counteracts vibration, noise, and end play
  • Promotes component longevity by preventing excess wear
  • Ideal for preloading ball bearing applications
  • Installed using common hand tools

Flat Washers

Flat Washers

Flat washers are stamped from sheet material creating a thin plate with a hole in the center. They provide increased surface area to evenly distribute pressure over equipment, prevent pullout of fasteners, and relieve surface friction to prevent loosening when fastening uneven surfaces. This simple, yet necessary piece of hardware is available in a wide variety of sizes, finishes, and materials.

  • Offered in carbon steel, nickel, stainless steel, and nylon
  • Often used as spacers when extra clearance between objects is needed
  • Disperses loads applied by conventional threaded fasteners
  • Easily installed using common hand tools

Quick Repair Washers

Quick Repair Washers

Quick repair washers, sometimes referred to as snap washers or split washers, are a hinged, two piece, steel fastener that can be radially installed and secured by tapping shut with a hammer. They are often used in agricultural applications where extra spacing or shimming is required. Radial application allows for removal and installation of part without taking apart other mechanical components in the assembly.

  • Available in corrosion resistant zinc clear finish
  • No need to take apart the assembly to replace or install
  • Offered in inch sizes ranging from 3/4 to 2‑1/8

TEC Series Washers

TEC Series washers by Sherex are a two piece, pre‑assembled, two piece wedge locking washer. The pair of joined washers feature cams on the mating face and ridges on the other. The two washers are joined with a mild adhesive on the cam side of the washer and installed between conventional threaded fasteners and a joining substrate. TEC washers use tension to secure a joint rather than the frictional force that is applied by traditional washers.

  • Pre‑assembled washers offer easy installation
  • Vibration proof according to MIL‑STD‑1312‑7
  • Installed using common hand or pneumatic tools
  • TEC washers are reusable with consistent self‑locking results
  • Reusable, heavy duty wedge locking washers

Wave Washers

Wave Washers

Wave washers, also commonly referred to as wave springs or coiled wave springs, are used to absorb stress due to axial compressive loads, acting as a cushion. The waves of the wave washer provide 3, 4, or 6-point contact that results in greater load‑bearing capacity and a medium range of deflection. The height and material thickness regulate the load function. Wave spring washers are typically used in thrust‑loading applications for small deflections, particularly where radial space is limited. Wave washers can help offset tolerance deviations in the assembly process and reduce loosening due to vibration.

  • Available in carbon and stainless steel
  • Offered in clear zinc, yellow zinc, and black oxide finishes
  • Requires less operating space than traditional coil springs
  • Evenly distributes applied loads
  • Minimal sharp edge interference or gall

FREQUENTLY ASKED QUESTIONS
By Type

Why use Belleville washers?

Belleville washers, also referred to as disc spring washers or conical washers, offer high load tolerances in limited space applications, often being used in bolted assemblies to maintain load or tension. Their load deflection curve can be linear or non‑linear depending on their height to thickness ratio. Belleville washers can also be stacked to increase load tolerance and deflection.

How to install Belleville washers:

Belleville washers, sometimes referred to as disc spring washers, can be installed in single, parallel, series, or series/parallel configurations.

Single Belleville washer configurations consist of a singular washer paired with a bolt or machine screw. The washer is positioned with the center protruding away from the work piece and contacting the head of the fastener.

Parallel configurations consist of two or more washers stacked on top of one another in a manner that allows them to have complete surface contact with each other. This configuration increases the load tolerance in multiples of the number of washers added. Two washers stacked doubles the load tolerance, three washers triples it, and so on.

Series configurations consist of two or more washers stacked on top of each other in such a manner that only the ends and the center face come in contact with each other. This configuration increases deflection tolerances in multiples of the number of washers added. Two washers stacked doubles the load tolerance, three washers triples it, and so on.

Series/Parallel configurations consist of stacking three or more washers together in a series and parallel combination. This method increases both load and deflection tolerances incrementally based on the number of washers that are added to or removed from the stack.

Can Belleville washers be re‑used?

Typically, Belleville washers can be reused. However, if the disc spring shows any signs of damage or the overall height is not within tolerance, it should be replaced.

How are curved washers used?

Curved washers, or crescent washers, are commonly used for simple spring applications. Curved washers exert relatively light thrust loads and are often used to absorb axial end play or as lock washers for fasteners. They generate high force within a very short spring length when compressed. The height of the form and material thickness are variables which can be adapted to a specific load/deflection function.

What is a Disc-Lock washer?

Disc-Lock washers, or wedge locking washers, are a pre‑assembled, two piece system consisting of two washers featuring raised wedges on the face. The wedges lock together resisting torque loads that cause unwanted loosening of the parent fastener. Loosening forces imposed on the fastener are directed to the wedge lock washer which creates a wedge effect preventing the fastener from rotating loose. Disc-Lock washers are recommended for applications with permanent joints where fasteners will not need to be removed.

How to install a Disc-Lock washer:

Disc-Lock washers can be installed using common hand or air tools. To install, place the washer assembly between the work piece and parent fastener. As the fastener is tightened, the washer applies tension to the work piece and the fastener. Disc-Lock washers should only be installed on smooth, metal surfaces. If installed correctly, a Disc-Lock washer will not require any re-tightening.

How do wedge lock washers work?

Wedge lock washers like the TEC Series washers and Disc-Lock washers use tension rather than friction to prevent conventional fasteners such as nuts and bolts from loosening. Wedge lock washers are composed of two washers mated together by a mild adhesive. Each component features cams on their inner face and seizing ridges on the outer face.

When the assembly is installed, the seizing ridges contact the fastener and joining material. When loosening torque loads are applied to the fastener, the stresses are directed to and absorbed by the washer. As the washer rotates, the cams push against each other creating tension between the work piece and the fastener. Because the cams are designed with greater angles than the thread pitch, a wedge effect is created thus preventing unwanted loosening of the fastener.

What is a fender washer?

Fender washers are a simple fastener component manufactured from a cylyndrical slug of metal with a center hole. Fender washers are similar to standard washers, however their outside diameter is much larger in proportion to the center hole. Fender washers provide surface area for force distribution compared to standard flat washers. They are commonly found in automotive, electrical, and plumbing applications.

When to use a fender washer:

Fender washers are typically used to distribute the load of a threaded fastener over larger surface area. Bolts or other fasteners may tear through thin sheet metal, plastics, or other thin substrates causing joint failure and damage to the material.

What is a finger washer?

Finger spring washers, or finger disc springs, are used for preloading ball bearings and general applications. They counteract excess wear, vibration, and noise. Finger spring washers are extremely useful in applying preload where unavoidable end play exists due to special application conditions, thus giving a rotation assembly greater running accuracy. They promote efficiency and smooth operation, reducing skidding and wear on rotating elements.

How to measure a flat washer:

Flat washers each have an inside diameter, outside diameter, and thickness. The inside diameter is the most critical measurement to ensure compatibility with the bolt or screw. Inside diameter is measured as the length of the center line of the center hole. The outside diameter is measured as the length of the center line that contacts the outer edges of the washer. Thickness is the height of the washer if it lies flat. Washers correspond to the screw or bolt diameter that they fit. A washer that fits a 1/2 inch shank will have an inside diameter slightly larger than 1/2 inch.

Flat Washer Tech Drawing

What size flat washer do I need?

The size of flat washer needed depends on the requirements of your specific application. Be sure to choose an inside diameter, outside diameter, and thickness that is right for your application.

Inside diameter: Ensure that you choose a washer with an inside diameter that is slightly wider than the diameter of your fastener's shank. The inside diameter of the washer should only be wide enough for the fastener shank to pass through without catching. If the inside diameter is too large, then the washer will sit off center from the fastener head.

Outside diameter: A larger outside diameter should be chosen for softer and thinner material to prevent the bolt head or nut from pulling through the material.

Thickness: Thicker washers have higher strength for use with larger bolts or heavy duty applications. Washers should not be used as spacers in critical applications.

What is a flat washer used for?

Standard flat washers are used to disperse the load of a bolt or screw subjected onto a work piece. This reduces the risk of the fastener head tearing through the substrate resulting in a failed joint.

What are quick repair washers?

Quick repair washers, sometimes referred to as snap washers or split washers, are a hinged, metal washer that allows for radial installation or removal without disassembling mechanical components.

What is a quick repair washer used for?

Quick repair washers can be used anywhere there is a need for radially installing spacers or shims. They are found on agricultural equipment including balers, corn heads, and lift cylinders. They are often used for shimming in power transmission applications.

What is a TEC Series washer?

TEC Series washers are a two piece, pre‑assembled, two piece wedge locking washer. The pair of joined washers feature cams on the mating face and ridges on the other. The two washers are joined with a mild adhesive and installed between conventional threaded fasteners and the joining substrate. TEC Series washers use tension to secure a joint rather than frictional force that is applied by traditional washers.

How to install a TEC Series washer:

TEC Series washers can be installed using common hand tools. To install, simply place the washer assembly between the desired nut or bolt and the joining substrate. As the nut or bolt is tightened, one half of the washer will be seated against the work piece and the other half will be seated against the nut or bolt. It is recommended to use a lubricant when installing TEC Series washers as this will reduce friction during installation and provide more consistent clamp load on joints.
