Value Collection P20005 Locking Cotter Pin 3/8 in Shaft

Product Description

The VALUE COLLECTION P20005 is a locking cotter pin designed to secure pins, shafts, and fasteners against vibration-induced loosening in mechanical assemblies. Built from RC 60-70 spring steel with a zinc-plated finish, it delivers reliable corrosion resistance and consistent spring tension across a range of industrial and trade applications. The pin features a 3/8 inch shaft diameter, an overall length of 1.214 inches, and a wire diameter of 0.054 inches. The ring diameter ranges from 0.382 to 0.392 inches, allowing it to snap securely into place once installed. Licensed mechanics, millwrights, and maintenance technicians commonly stock these as a consumable fastener component.

This locking cotter pin is suited for use in equipment with 3/8 inch pin or clevis arrangements where a positive locking fastener is required. Typical applications include linkage pins, clevis pins, hitch pins, and similar mechanical connection points found in HVAC equipment, pumping systems, and general industrial machinery. It is sold individually with a minimum order quantity of 100 units, making it appropriate for stocking in a parts inventory or service vehicle supply.

Key Features

• Spring steel construction rated RC 60-70 provides consistent locking spring force
• Zinc-plated finish offers corrosion resistance for general indoor and light outdoor use
• 3/8 inch shaft diameter fits standard clevis and hitch pin arrangements
• Wire diameter of 0.054 inches for reliable grip without deformation under load
• Ring diameter range of 0.382 to 0.392 inches ensures positive snap-in retention
• Overall length of 1.214 inches suits compact fastener applications

Compatibility

Designed as a standard locking cotter pin replacement for mechanical assemblies requiring a 3/8 inch shaft diameter fastener with spring-steel construction.

Installation Notes

Installation of locking cotter pins requires no special tools beyond standard hand tools. Always de-energize and lock out any equipment before servicing linkage or pin connections. Insert the pin through the shaft hole until the ring snaps into the groove; do not force or over-compress the ring, as this may reduce retention force. Inspect the pin for deformation or corrosion and replace if the spring tension appears compromised.
