Value Collection MP40910 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION MP40910 is an extended prong cotter pin designed to secure clevis pins, shaft assemblies, and fastener connections across a wide range of mechanical, industrial, and trade applications. Measuring 3/32 inch in diameter and 1-1/2 inches in length, this cotter pin is manufactured from Grade 2 steel with a zinc-plated finish for corrosion resistance. The extended prong design allows the legs to be bent back securely after insertion, locking the pin in place and preventing loosening under vibration or load. Machinists, millwrights, HVAC technicians, plumbers, and general maintenance professionals commonly stock this fastener for routine service and repair work.

This cotter pin is suited for residential and light commercial applications where a small-diameter, standard-length cotter pin is required. Typical uses include securing clevis pins on linkage assemblies, locking castle nuts on threaded shafts, and retaining pins in hinges or brackets. The zinc plating provides modest protection against moisture and oxidation, making it appropriate for sheltered mechanical environments. It is sold individually with a minimum order quantity of 50 units, making it practical for shop stock or bulk service inventory.

Key Features

• Extended prong design allows legs to be spread and bent back for a secure, vibration-resistant lock
• Grade 2 steel construction provides adequate strength for standard fastener retention applications
• Zinc-plated finish offers corrosion resistance in sheltered or low-moisture environments
• 3/32 inch diameter suits small clevis pins, castle nuts, and shaft retention hardware
• 1-1/2 inch length accommodates standard insertion depth with sufficient leg length for bending

Compatibility

Designed as a general-purpose extended prong cotter pin for use in mechanical assemblies requiring a 3/32 inch diameter pin with a 1-1/2 inch length.

Installation Notes

Cotter pins are installed by a wide range of trades including HVAC technicians, plumbers, and maintenance mechanics. Always insert the pin fully through the hole in the shaft or clevis pin before spreading the prongs. Use needle-nose pliers to bend the extended legs back against the fastener after insertion — never reuse a previously installed cotter pin. Ensure the assembly is depressurized or de-energized before accessing the hardware being secured.
