Aztec Lifting Hardware

Machinery lifting eye bolts consist of a thread shank with an eye (loop or ring) at one end. The threaded shank is fully installed into a tapped hole in a piece of equipment or machinery for lifting. Lifting eye bolts come in plain pattern for zero degree (non‑angled) vertical lifts or shouldered for angular lifts. DIN standard lifting eyes are also available for handling additional angular stress.

Machinery lifting eye nuts consist of a metal loop, or lifting eye, with a tapped hole on one side. Lifting eye nuts are installed on a threaded shank or post that protrudes from a piece of equipment or machinery. Lifting eye nuts come in plain pattern for zero degree vertical lifts or shouldered for angular lifts. DIN standard lifting eyes are also available.

Swivel Hoist Rings, or center-pull-hoist rings, feature a 180‑degree pivot and 360‑degree swivel to allow for lifting from nearly any direction. The ring absorbs any pitch, roll, or sway of an unbalanced load in order to complete the lift safely.

Nut eye bolts consist of a threaded shank or shaft with an eye at one end. The shank is inserted into an untapped hole and will protrude through the bottom of the hole. A nut secures the end of the shank and prevent the nut eye bolt from pulling back out. Nut eye bolts come in plain pattern for zero degree vertical lifts or shouldered for angular lifts.

Screw eye bolts, or lag eye bolts, consist of a screw threaded shank with an eye at one end. The screw end is threaded into wood or a lag anchors. Screw eye bolts come in plain pattern for zero degree vertical lifts or shouldered for angular lifts.

Bent wire eye bolts, sometimes referred to as closed eye bolts, wire eye bolts, or turned eye bolts, are a steel wire fastener featuring a nearly closed loop on one end and threaded shank on the other. Designed for through‑hole applications, bent wire eye bolts are often used for lashing and suspension within its appropriate load limit. Bent wire eye bolts are not to be used for rigging or lifting as the eye loop can open under heavy loads.

Positioning swivels are created from two rigging end fittings held together by a threaded shank and nut. Positioning swivels are designed to allow movement prior to loading to align rigging hardware, but cannot swivel freely once the load has been applied. Eye x eye swivels and eye x jaw swivels are available.

Anchor shackles, or bow shackles, have a rounded, O‑shaped bow to allow for side loading and sling-leg connections. Chain shackles, or D shackles, have a narrow bow for in‑line towing, hoisting and rigging applications. A pin is placed in the ears of the bow to secure slings, chains or rope in the shackle.

Clevis rod ends are a U‑shaped fastener that allow for the quick and easy connection or removal of a variety of lifting and rigging components. Clevis ends come tapped and threaded for use with a threaded rod or as an untapped blank. Double clevis ends are popular for connecting chain ends to rings, end links, hooks or eye bolts.

Yoke ends (often confused with clevis ends) are a U‑shaped fastener that allow for the quick and easy connection or removal of a variety of lifting and rigging components. Yoke ends tend to be an off the shelf alternative to clevis ends, and come tapped and threaded for use with a threaded rod or as an untapped blank.

Rod ends, or swing bolts, are available as blanks that can be cut, drilled, tapped, threaded, or welded to make control arms, custom eye bolts, and other levers, or they can be machined to order to meet the requirements of your application.

Grab hooks have a narrow throat to prevent chain from slipping. Slip hooks, or sling hooks, have a wider throat to allow chain to move to take up slack. Grab hooks and Slip hooks are available with clevis or eye sling attachments. Light duty snap hooks, or rigging carabineers, with a self‑closing latch are also available.

Durable grade 70 transport chain is available in lengths up 100 feet for load securement and towing. Grade 70 chain is available with or without a clevis end grab hook. Grade 30 proof coil chain is an economical option for light duty construction and agricultural applications. NOTE: Grade 70 and grade 30 chain is not approved for overhead lifting.

Cold shut links, quick link connectors and repair links are a fast, easy and inexpensive way to repair, join or extend chains and couplers in the field. Master links are an integral part of rigging and sling assemblies or can be used a standalone rigging accessory.

Wire rope clips can be used to form a load bearing loop at the end of a wire rope or cable. U‑bolt and double saddle, or fist grip, wire rope clips are available. Thimbles can also be used to help preserve the size and shape of the loop. Swage sleeves can also be used to create a loop or lag splice for cable ends.

A turnbuckle assembly is a common piece of rigging hardware that is used to reduce slack or adjust tension. Turnbuckles typically consist of three components, a body with a tapped hole on each side (one left-hand threaded and one right-hand threaded) and two end fittings. Common end fittings have a hook, jaw or eye at that end of a threaded shank. Alternately, a threaded shank called a stub end can be used.
