Value Collection 3SCP20300 Cotter Pin 5/16 in 3 in Ss 5-pack

Product Description

The VALUE COLLECTION 3SCP20300 is an extended prong cotter pin designed to secure fasteners, clevis pins, and axle pins against loosening or backing out in mechanical assemblies. Measuring 5/16 inch in diameter and 3 inches in usable length, this pin is constructed from 18-8 stainless steel with an uncoated finish, offering corrosion resistance suitable for wet, outdoor, or chemically exposed environments. Extended prong cotter pins spread after insertion to lock the pin firmly in place. This part is sold in a pack of 5 units. Installation is performed by maintenance technicians, millwrights, or field service professionals working on mechanical linkages, agricultural equipment, trailers, and similar assemblies.

This extended prong cotter pin is suited for residential, commercial, and industrial applications where a reliable mechanical locking fastener is required. Common install scenarios include securing castle nuts on wheel assemblies, locking clevis pins on linkage systems, and retaining axle pins on trailers and agricultural implements. The stainless steel construction makes it a practical choice for outdoor, marine-adjacent, or washdown environments where plain steel fasteners would corrode prematurely.

Key Features

• Extended prong design spreads after insertion for a positive mechanical lock
• 18-8 stainless steel construction provides corrosion resistance in wet and exposed environments
• 5/16 inch diameter fits standard clevis pins, castle nuts, and axle pin bores of matching size
• 3-inch usable length accommodates thicker assemblies and wider pin bores
• Uncoated finish — no risk of coating flaking into assemblies
• Pack of 5 units per order

Compatibility

Designed as a standard extended prong cotter pin replacement for mechanical assemblies requiring a 5/16 inch diameter cotter pin with a 3-inch usable length.

Installation Notes

Cotter pins are installed by maintenance technicians and mechanical service professionals using standard needle-nose pliers or cotter pin pullers. Always relieve load from the assembly and, where applicable, de-energize or lockout the equipment before servicing fasteners. Insert the pin fully through the bore, then spread the prongs in opposite directions to lock — do not reuse a previously bent cotter pin, as the metal fatigues at the bend point. Dispose of removed pins and install new ones at each service interval.
