Pack contents and purpose
This pack contains 40 zinc plated steel cotter pins sized 9/64 inch by 1-3/4 inch. They are split pins with two tines that bend during installation to secure metal components in place of a staple or rivet. Suitable for automotive, machinery and general hardware tasks where a removable locking fastener is needed. Buyers who need a different diameter or length should look elsewhere.
Material and finish
Zinc plated steel provides corrosion resistance for exposed or outdoor assemblies. The pins install by inserting through a hole and bending the tines outward, requiring only basic hand tools. No special thermal, noise or power considerations apply to this passive hardware.
Critical fit dimension
The 9/64 inch diameter and 1-3/4 inch length are the sole specifications that determine whether this part fits your application. Verify the hole size and required pin length before ordering.

Questions about this item
How do I install the 9/64" cotter pin through the castle nut and what step do people miss?
Insert the pin through the nut and bolt hole, then spread both tines fully in opposite directions; the step often missed is bending both legs completely so the pin cannot rotate or back out.
What maintenance will the zinc-plated steel pins need after installation?
Inspect periodically for corrosion or deformation; replace any pin that shows white rust, bent tines, or looseness in the hole.
What limit appears first when these pins are under sustained vibration?
The split tines can fatigue and straighten, allowing the pin to work loose from the castle nut slot.
