Value Collection P20121 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION P20121 is an extended prong cotter pin used to secure clevis pins, shaft assemblies, and other fastener applications where a positive mechanical lock is required. Measuring 0.25 inches in diameter and 1.25 inches in length, this pin is fabricated from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. The extended prong design allows the legs to be bent back firmly over a mating component for a secure, tamper-resistant connection. Plumbers, millwrights, HVAC technicians, and general maintenance trades install these pins in linkage assemblies, actuator rods, and bracket connections across light industrial and mechanical systems.

This cotter pin is suited for residential and light commercial mechanical assemblies where a reliable, removable locking fastener is needed. Typical applications include HVAC damper linkages, valve actuator connections, equipment brackets, and general fabrication work. The zinc plating makes it appropriate for indoor environments and applications with limited moisture exposure. It is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• Extended prong configuration allows legs to be spread and bent securely over mating parts
• Grade 2 steel construction provides adequate strength for light-duty mechanical locking applications
• Zinc-plated finish offers basic corrosion resistance for indoor and sheltered installations
• 0.25 inch diameter fits standard clevis and shaft pin holes of the same nominal size
• 1.25 inch length accommodates typical material stack thickness in bracket and linkage assemblies

Compatibility

Designed as a standard extended prong cotter pin for use in light-duty mechanical fastener applications requiring a 0.25 inch nominal diameter locking pin.

Installation Notes

Installation requires no special tools beyond standard needle-nose pliers to spread and bend the prong legs after insertion. Ensure the host pin or shaft is fully seated before inserting and bending the cotter pin. Do not reuse a cotter pin once the prong legs have been bent, as metal fatigue can reduce holding strength. Follow applicable mechanical codes and equipment manufacturer guidelines when servicing assemblies that use cotter pins as safety-critical locking elements.
