Purpose and User
This pack supplies 100 zinc-plated steel cotter pins measuring 3/16 inch by 1 inch. Mechanics, fabricators and maintenance teams use them to lock castle nuts, clevis pins and drilled shafts on vehicles, farm equipment and general machinery.
Fit and Limits
The split-pin design suits single-use locking jobs where a bent tine provides positive retention. Builders who need reusable quick-release fasteners, larger diameters or stainless steel for marine corrosion resistance should look at other hardware types.
Installed Behaviour
Once the tines are spread, the pin resists vibration and axial loads without loosening. The zinc plating protects the steel during storage and initial service, while the 100-piece quantity covers multiple assemblies or field repairs without reordering.

Questions about this item
What size drill bit or hole do I need for these 3/16" cotter pins?
Drill a 3/16" hole through the bolt or shaft so the pin slides through before you bend the tines.
Can I use these zinc plated pins on stainless steel bolts without corrosion issues?
Zinc plating protects the pin itself; galvanic corrosion risk is low for occasional automotive use but stainless hardware is preferable for constant immersion.
How do I confirm each pin is seated correctly after bending the tines?
Both tines should be bent back flat against the nut or washer with no gap, locking the assembly so it cannot rotate or back off.
