Hillman Fasteners 8000 Cotter Pin Assortment 50 Pack

Product Description

The HILLMAN FASTENERS 8000 is a 50-piece assortment of tool box cotter pins, sized from 1/2 inch to 1-1/2 inches. Cotter pins are split fasteners inserted through a drilled hole in a bolt, shaft, or clevis pin to prevent lateral movement and accidental disassembly. This assortment covers a range of common pin lengths, making it practical for general mechanical work, equipment repair, and maintenance tasks. Plumbers, HVAC technicians, electricians, and general maintenance trades keep cotter pin assortments on hand for securing linkage pins, clevis connections, and castellated nut applications across a wide range of mechanical systems.

This assortment is suited for residential and light commercial maintenance environments where multiple cotter pin sizes are needed on a single job or across a variety of recurring service calls. The tool box format keeps the pins organized and accessible. Typical applications include securing clevis pins on equipment linkages, locking castellated nuts on shafts, and retaining pins in agricultural or mechanical assemblies. The size range of 1/2 inch to 1-1/2 inches covers the most commonly encountered fastener requirements in general trade service work.

Installation Notes

Cotter pins are installed by a qualified mechanic or trade professional after inserting the pin through the drilled hole of the mating fastener or shaft. Once inserted, the legs are bent outward or folded back to lock the pin in place. Always use a new cotter pin when reassembling — never reuse a previously bent pin. Ensure the hole diameter and pin diameter are properly matched before installation to maintain a secure connection.
