Value Collection 40955 Extended Prong Cotter Pin 5/16x2.5in

Product Description

The VALUE COLLECTION 40955 is an extended prong cotter pin used to secure clevis pins, castle nuts, and similar fasteners in mechanical assemblies. Manufactured from Grade 2 steel with a zinc-plated finish, this pin measures 5/16 inches in diameter and 2-1/2 inches in length. The extended prong design allows the legs to be bent back over a fastener or through a slotted opening with minimal clearance. The zinc plating provides basic corrosion resistance in dry to mildly humid environments. Machinists, millwrights, agricultural equipment technicians, and general maintenance trades install this type of pin across a wide range of equipment and machinery applications.

This cotter pin is suited for use in agricultural equipment, industrial machinery, automotive linkages, trailers, and general mechanical assemblies where a positive locking method is needed on a drilled pin or slotted fastener. The extended prong style is preferred when additional bending length is required during installation or when the application demands a more secure prong wrap. Single-use fastener — replace with a new pin each time the assembly is disassembled.

Key Features

• Extended prong design provides additional leg length for secure bending in tight assemblies
• Grade 2 steel construction for standard-duty mechanical fastening applications
• Zinc-plated finish for basic corrosion resistance in dry or mildly humid environments
• 5/16 inches diameter fits standard drilled clevis pins and castle nut slots of matching bore
• 2-1/2 inches overall length accommodates thicker assemblies and deeper prong wrap
• Single-use fastener designed for one-time installation per assembly cycle

Compatibility

Designed as an OEM-style replacement or maintenance-stock cotter pin for mechanical assemblies requiring a 5/16 inches diameter extended prong cotter pin in Grade 2 zinc-plated steel.

Installation Notes

Installed by machinists, millwrights, or general maintenance technicians using standard needle-nose pliers or cotter pin tools. Insert the pin fully through the drilled hole or slotted fastener before bending the prongs — do not bend before seating. Cotter pins are single-use fasteners and must be replaced, not reused, any time the assembly is taken apart. De-energize or lock out any equipment before servicing pinned linkages or rotating assemblies per applicable safety procedures.
