What the pins do

These zinc-plated steel cotter pins secure metal assemblies by spreading their two tines after insertion. The 40-piece pack supplies enough fasteners for multiple automotive or machinery tasks. Each pin acts like a staple or rivet that can be removed and reused if the tines stay intact.

Practical limits of the split-pin design

The pins work only where a drilled hole matches their diameter and a castle nut or similar keeper can hold them in place. Vibration can straighten bent tines over time, so they are not suited for high-load structural joints without secondary locking. Corrosion resistance depends on the zinc coating remaining unbroken.

Installation notes and common issues

Insert the pin through the aligned holes, then bend both tines outward with pliers to lock the assembly. The most frequent problem is tines snapping if bent too sharply or reused after work-hardening. Ensure the hole is clean and the correct diameter so the pin seats fully before bending.

Questions about this item

Is the 40-pack the only quantity available?

What does the 9/64-inch diameter mean for a drilled hole?

The 9/64-inch shank fits a matching hole size so the split pin can be inserted and the tines bent to secure the assembly.

How does the zinc plated steel hold up in automotive use?

Zinc plating on the steel pins provides corrosion resistance for general automotive and hardware fastening applications.
