Value Collection C207-CPS3122000 Cotter Pin 5/16x2 in

Product Description

The VALUE COLLECTION C207-CPS3122000 is an extended prong cotter pin used to secure fasteners, clevis pins, and shaft assemblies against loosening from vibration or load cycling. Manufactured from 18-8 stainless steel with an uncoated finish, it delivers corrosion resistance suited to wet, outdoor, or mildly chemical-exposed environments. The pin measures 0.3125 inches in diameter and 2 inches in usable length. The extended prong design allows the prongs to be bent back over a mating component for a secure mechanical lock. Maintenance technicians, millwrights, and general tradespeople install these pins across a wide range of mechanical and structural assemblies.

This cotter pin is used in light mechanical assemblies, equipment linkages, agricultural hardware, HVAC equipment panels, and plumbing fixture brackets where a reliable anti-rotation or retention fastener is needed. The 18-8 stainless steel construction makes it appropriate for applications where mild corrosion resistance is required without the cost of higher-alloy materials. Sold individually, with a minimum order quantity of 5 units per order.

Key Features

• Extended prong design locks securely when prongs are bent over the mating part
• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• Uncoated finish — no plating to chip or flake under repeated bending
• 0.3125-inch diameter fits standard clevis pin and shaft bore holes sized for 5/16-inch cotter pins
• 2-inch usable length accommodates thicker castings, brackets, and stacked assemblies
• Lightweight at 0.01 pounds — minimal added mass to fastened assemblies

Compatibility

Designed as a general-purpose extended prong cotter pin for use in standard 5/16-inch cotter pin holes across mechanical, structural, and equipment-maintenance applications.

Installation Notes

De-energize and lock out any equipment before servicing pinned linkages or shaft assemblies. Insert the cotter pin fully through the hole so the head seats flush, then spread the prongs in opposite directions to secure the pin in place. Use needle-nose pliers to bend prongs cleanly without fracturing the pin body. Inspect the pin for deformation or corrosion at each scheduled maintenance interval and replace if any damage is found.
