square loop wire lock pin with tab
These Square-Loop Wire Lock Pins combine the benefits of a pin and cotter combination in a single, dependable assembly. They are specialty locking pins and are good for quick-release applications by simply pulling the wire loop over the pin to lock it in place. They can be used as a convenient way to adjust or remove accessories on equipment.
Hitch Pin and Linch Pin Operation
All of the types of pins listed in this selection guide require at least one predrilled hole that is meant to hold and retain objects in place. For coupling applications, two mating segments are aligned and then held in position by the pin. Hitch pins and clevis pins require an additional cotter pin inserted perpendicularly to lock the pin in position. Linch pins, detent pins, snapper pins, safety spring pins, and toggle pins all contain integral locking mechanisms.
Like other pins, these devices are meant to resist shear forces, which make them fundamentally different than bolts and screws. Sometimes these can be used as shear pins in mechanical overload situations.
Hitch Pin and Linch Pin Production
Since hitch and linch pins are meant to resist shearing under heavy loads, their material of construction is almost exclusively metal.
- Hardened and ground steel undergoes a heat treatment process that compacts carbon atoms, resulting in a stronger but more brittle version of the metal. If uncoated, it is likely to oxidize under certain conditions.
- Unhardened steel is more malleable and less expensive, but also cannot handle extreme loads. It is vulnerable to corrosion.
- Stainless steel is corrosion resistant, aesthetically appealing, and exceptionally strong, but is also more expensive than other steel options.
- Brass provides quality strength, conductivity, corrosion resistance, and low-magnetic permeability, but is limited to a lower working load.
Production of hitch and linch pins is represented by the infographic below.
Hitch Pin and Linch Pin Configurations
Several types of hitch and linch pins exist, mostly differentiated by their locking mechanism. Hybrid styles of two pin types covered below are very common.

Hitch Pin and Linch Pin Applications
Hitch pin and linch pins are recognizable from their common usage in towable trailers, such as boat trailers and campers. Snapper pins are sometimes used on trailer jacks as well. Clevis pins are common in many industries and are identifiable in rigging for sailboats and in servos for model aircraft. Detent pins are common in exercise equipment. Toggle pins are an easy way to assemble and disassemble scaffolding.
