Value Collection 40960 Extended Prong Cotter Pin 5/16x6 in

Product Description

The VALUE COLLECTION 40960 is an extended prong cotter pin designed to secure clevis pins, shaft assemblies, and fastener systems in mechanical and structural applications. Manufactured from Grade 2 steel with a zinc-plated finish, this pin measures 5/16 inches in diameter and 6 inches in usable length. The extended prong design allows the legs to be bent back securely after insertion, providing reliable retention in high-vibration environments. It is a standard consumable used by maintenance mechanics, millwrights, plumbers, and general tradespeople across industrial, agricultural, and utility service applications.

This cotter pin is suited for residential and commercial maintenance work wherever positive pin retention is required. Common applications include linkage assemblies, valve stems, clevis attachments, and general mechanical fastening tasks. The zinc-plated finish provides basic corrosion resistance for indoor and light outdoor use. The 6-inch length accommodates thicker assemblies or installations requiring extra material for prong bending after insertion.

Key Features

• Extended prong design allows secure leg bend-back for positive mechanical retention
• Grade 2 steel construction provides reliable strength for standard fastening loads
• Zinc-plated finish offers basic corrosion resistance in light-duty environments
• 5/16 inches diameter fits standard clevis and shaft pin applications
• 6 inches usable length accommodates thicker assemblies and deep installations

Compatibility

Designed as a standard extended prong cotter pin for use in clevis pin assemblies, linkage systems, and general mechanical fastening applications requiring a 5/16-inch diameter pin.

Installation Notes

Installation requires no special tools beyond needle-nose pliers for bending the prongs after insertion. Ensure the shaft or clevis hole diameter is sized to accept a 5/16-inch pin before installation. Always bend prongs fully outward after insertion to prevent backing out during operation. Inspect and replace cotter pins any time a joint is disassembled - never reuse a bent cotter pin.
