Value Collection C207-CP3123000 Cotter Pin 5/16x3 in

Product Description

The VALUE COLLECTION C207-CP3123000 is an extended prong cotter pin designed for mechanical fastening applications where positive locking is required. Manufactured from Grade 2 steel with a zinc-plated finish, this pin measures 5/16 inches in diameter and 3 inches in usable length. The extended prong design provides a longer bendable leg that wraps securely around mating fasteners, reducing the risk of vibration-induced loosening. It meets ASME B18.8.1 standards and is RoHS compliant. Maintenance technicians, millwrights, and general mechanical trades use this style of cotter pin across a wide range of industrial and equipment-service tasks.

This cotter pin is suited for use in clevis pins, castle nuts, axle retainers, linkage assemblies, and similar mechanical connections found in industrial equipment, agricultural machinery, HVAC linkage systems, and general mechanical assemblies. The zinc plating provides a degree of corrosion resistance for light-duty outdoor or moisture-exposed environments. It is sold individually per package, with a minimum order quantity of 100 units, making it appropriate for shop stock, maintenance carts, or bulk replenishment.

Key Features

• Extended prong configuration for secure mechanical locking around fasteners
• Grade 2 steel construction meets ASME B18.8.1 dimensional standards
• Zinc-plated finish for light corrosion resistance
• RoHS compliant materials
• 5/16 inch diameter with 3 inch usable length for medium-duty fastening applications

Compatibility

Designed as a standard-dimension replacement or stock cotter pin for use with clevis pins, castle nuts, and slotted fasteners requiring a 5/16 inch diameter extended prong cotter pin per ASME B18.8.1.

Installation Notes

Installation is typically performed by maintenance mechanics or millwrights using needle-nose pliers or cotter pin tools. Always de-energize and lockout/tagout any equipment before accessing pinned linkage assemblies. Insert the pin fully through the mating hole, then bend the prongs apart against the fastener face to secure. Do not reuse a previously bent cotter pin, as fatigue at the bend point reduces holding reliability.
