Value Collection KP80780 Locking Cotter Pin 3/8 in Shaft

Product Description

The Value Collection KP80780 is a locking cotter pin designed for securing components on shafts in mechanical assemblies. It features a 3/8 inch shaft diameter and a body length of 1.214 inches, with a wire diameter of 0.054 inches. The ring diameter ranges from 0.382 to 0.392 inches, providing a positive lock once seated on the shaft. Constructed from RC 60-70 rated spring steel with a zinc-plated finish, this pin delivers reliable corrosion resistance and mechanical durability in typical industrial and trade maintenance applications. It is installed by maintenance technicians and mechanical tradespeople during equipment servicing and assembly.

This locking cotter pin is suited for use in general mechanical applications where a positive shaft retention method is required. Common installation scenarios include securing clevis pins, axles, linkage rods, and similar fastening points in HVAC equipment, pump assemblies, and general mechanical systems. The zinc-plated finish provides moderate corrosion protection for use in dry to mildly humid environments. Each package contains 25 pins, making it practical for service vehicles and shop stock.

Installation Notes

Installation is typically performed by maintenance technicians and mechanical tradespeople using standard pliers or cotter pin tools. Always de-energize and lock out equipment before servicing any mechanical assembly. Confirm shaft diameter and pin ring diameter clearance before installation to ensure proper engagement and retention. Inspect the pin for deformation or corrosion before reuse and replace if any wear is evident.
