Pins, clips and retaining rings locate parts, hold shafts in place and keep linkages together on trailers, farm equipment, conveyors, gearboxes and machine guards. This section includes cotter pins, clevis pins, hitch pins, hair pin (R) clips, quick release pins, dowel pins, slotted and coiled spring (roll) pins, lynch pins, and internal and external retaining rings, sometimes called snap rings or circlips.
What to check before you order
- Diameter and length. Pins are sized by nominal diameter and usable length. Measure the hole and the grip length through all parts.
- Pin type. Dowel pins are precision ground for exact location. Roll pins compress to hold by spring tension in a drilled hole and tolerate a looser fit.
- Retaining ring style. External rings fit a groove on a shaft and internal rings fit a groove in a bore. Check the groove diameter, not just the shaft size.
- Tools. Most ring styles need retaining ring pliers with the correct tip size to install and remove them safely.
- Material. Zinc-plated steel is common. Stainless suits outdoor and washdown equipment.
Common questions
Can I reuse a cotter pin?
It is good practice to use a new cotter pin each time. Bending the legs fatigues the metal, and a reused pin can break.
