Value Collection KP35017-1 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION KP35017-1 is an extended prong cotter pin designed for use in mechanical assemblies where a secure, removable fastening solution is required. Manufactured from Grade 2 steel with a zinc-plated finish, this pin measures 0.125 inches in diameter and 3 inches in usable length. The extended prong design allows the tines to be bent back around a shaft or clevis pin after insertion, locking the assembly in place. It is commonly installed by maintenance technicians, millwrights, and general tradespeople working on mechanical linkages, control rods, and pinned connections.

This cotter pin is suited for light-duty to medium-duty mechanical fastening applications across HVAC equipment, plumbing system components, and general industrial equipment. It fits standard clevis and castle-nut configurations where a 0.125-inch pin diameter is specified. The zinc-plated finish provides a basic level of corrosion resistance appropriate for indoor and sheltered outdoor environments.

Key Features

• Extended prong style allows secure tine spreading after installation
• Grade 2 steel construction provides adequate tensile strength for light to medium mechanical loads
• Zinc-plated finish offers corrosion resistance for general service environments
• 0.125-inch diameter fits standard clevis pin and castle-nut applications
• 3-inch usable length accommodates a range of shaft and fastener thicknesses

Compatibility

Designed as a standard-dimension extended prong cotter pin for use in mechanical assemblies requiring a 0.125-inch diameter pin in clevis, castle-nut, or pinned-linkage configurations.

Installation Notes

Installation requires no power shutoff but all mechanical motion in the assembly should be stopped and secured before fitting or removing cotter pins. Insert the pin fully through the hole, then spread the prongs apart using needle-nose pliers to lock it in position. Single-use removal is standard practice — cotter pins should not be reused after the prongs have been bent. Consult applicable equipment manufacturer documentation for specified pin diameter and replacement intervals.
