Automotive Cotter Pins 100-Pack
These zinc-plated steel cotter pins measure 5/32 inch by 1-1/4 inch and come in a 100-piece pack. They are designed to secure metal components by inserting the pin and bending the two tines. The fasteners suit automotive, agricultural and general repair tasks where a reliable mechanical lock is required.
Zinc-Plated Steel Durability
The zinc plating provides a layer of corrosion resistance that holds up during extended exposure to moisture, road salt and temperature swings. Under sustained vibration the split-pin design maintains clamping force without loosening, and the steel core resists shear loads that would deform softer materials.
Replaces Lost or Worn Split Pins
This pack replaces missing or fatigued cotter pins found on castle nuts, clevis pins and drilled bolts across a wide range of equipment. The quantity covers multiple jobs so technicians do not need to source individual pieces. Buyers who need stainless steel or a different diameter should look elsewhere.

Questions about this item
Does the zinc-plated steel finish on these 5/32" cotter pins resist heat and corrosion during long-term automotive use?
The zinc plating protects the steel pins from rust and handles normal under-hood temperatures without degrading.
What size drill bit or hole must I already have for the 5/32" diameter pins to fit correctly?
Drill a 5/32" hole through the mating parts so the pin slides in before you spread the tines.
Will these 1-1/4" pins work with the castle nuts and drilled bolts I already use on older equipment?
Yes, the 5/32" diameter and 1-1/4" length match standard castle-nut slots on many legacy assemblies.
