SKU CH-VA6Q-56RSH

Pack of 100 zinc-plated steel cotter pins for securing bolts and shafts

  • Product typePins
  • 100 pins per pack covers many fastening jobs
  • Zinc-plated steel resists corrosion in outdoor use
  • Split-pin design locks securely when tines are bent
  • 1/8" diameter fits standard drilled holes
  • 2" length suits a range of material thicknesses

Purpose and Pack Size

These zinc-plated steel cotter pins secure drilled fasteners in automotive, agricultural and general mechanical assemblies. The 100-piece pack supplies enough split pins for multiple maintenance jobs or a busy workshop.

Installation Behaviour

Each pin inserts through a drilled hole and the two tines are bent back to lock the joint against vibration and axial load. The zinc plating resists corrosion during extended outdoor or under-vehicle exposure.

Material and Daily Use

Manufactured from steel with a zinc coating, the pins withstand repeated bending without snapping. The 1/8 inch diameter fits standard castle nuts and drilled bolts, while the 2 inch length accommodates thicker shafts and multiple washer stacks.

Questions about this item

Do these zinc-plated steel pins generate any heat or noise when left in place for long periods?

No, the pins are passive metal fasteners with no moving parts or electrical components, so they produce zero heat and no audible noise during continuous use.

What additional parts or tools do I need before I can install these cotter pins?

You will need a drilled bolt or clevis pin that accepts a 1/8" diameter pin, plus pliers or a pin-bending tool to spread the two tines after insertion.

Will these pins work with older castle nuts or drilled bolts I already have in the shop?

Yes, as long as the existing hardware has a 1/8" cross-hole, the 2" length and standard split-pin design fit legacy castle nuts, clevis pins and drilled bolts without modification.
