THE REAL REPAIR PROBLEM

The Tiny Fastener You Notice Only When It's Missing.

Cotter pins help retain compatible clevis pins and slotted or castle nuts. When an old one is removed or damaged, having a new replacement nearby can help keep a repair moving.

MORE USEFUL THAN IT LOOKS

A Simple Design with a Practical Job.

A split pin passes through a suitable drilled hole, then its legs are bent to help keep a fastener in position. The correct size and installation method always depend on the equipment.

THREE STEPS TO UNDERSTAND THE PART

Choose It. Insert It. Secure It.

The principle is simple, but choosing the specified pin diameter and length is essential. Always follow your equipment's service instructions for safety-related repairs.

01Match the Size

Confirm the required diameter, length and material for the application.

02Insert a New Pin

Pass the correct cotter pin through the prepared hole after assembling the fastener properly.

03Secure the Ends

Bend the pin legs as specified to retain the connection. Replace used pins rather than reusing them.

A BETTER-PREPARED WORKSHOP

Keep Small Hardware on Your Checklist.

Cars, lawn equipment, agricultural machinery and utility hardware can all use cotter-pin-style fasteners in certain assemblies. Fit and installation requirements vary—check the manual before selecting a replacement.

QUICK QUESTIONS

Before You Add One to the Toolbox.

What is a cotter pin used for?

A split cotter pin is a retaining fastener used with suitable drilled pins, shafts, or castle nuts. Its legs are typically bent after insertion.

Can I reuse a cotter pin after removing it?

Generally, no. Bent or removed cotter pins should be replaced with the specified new part as directed by the equipment manufacturer.

Is this kit stainless steel?

Material grade and surface finish have not been confirmed for this 350-piece listing. Check the actual product specifications before ordering.

Does the kit include multiple sizes and a storage case?

Exact size distribution and packaging are not confirmed from the available original listing. Please verify the selected item's package details.

Can the pins be used on cars, trailers or lawn mowers?

Only where the pin's type, size, material and installation method match the equipment manufacturer's specification.

Are these the same as R-clips or spring hairpin clips?

No. Conventional split cotter pins have two legs that are typically bent during installation. R-clips and other retaining clips use different locking methods.
