Value Collection P20008 Locking Cotter Pin 5/8 in

Product Description

The VALUE COLLECTION P20008 is a locking cotter pin designed to secure shafts, clevis pins, and fastener assemblies against loosening under vibration or dynamic load. The pin fits a 5/8-inch shaft diameter and measures 1.69 inches in overall length. Wire diameter is 0.072 inches, and the locking ring diameter runs 0.635 to 0.645 inches. Constructed from RC 60-70 spring steel with a zinc-plated finish, this pin delivers reliable retention strength and basic corrosion resistance. It is a standard hardware component installed by mechanics, millwrights, HVAC technicians, and general maintenance professionals across light industrial and trade applications.

This locking cotter pin is suited for use in mechanical linkages, control rod assemblies, shaft retention applications, and clevis connections where a positive locking fastener is required. The zinc-plated spring steel construction makes it appropriate for general-purpose indoor and sheltered outdoor installations. Applications span HVAC damper linkages, equipment control arms, and mechanical assemblies where standard cotter pins are called for. This part ships in individual unit quantities with a minimum order of 100 units per order.

Key Features

• Fits 5/8-inch shaft diameter for secure retention in standard clevis and pin assemblies
• RC 60-70 spring steel construction provides consistent locking tension and fatigue resistance
• Zinc-plated finish offers basic protection against oxidation in sheltered environments
• 0.072-inch wire diameter with a ring diameter of 0.635 to 0.645 inches
• 1.69-inch overall length accommodates standard shaft and clevis configurations

Compatibility

Designed as a general-purpose locking cotter pin for mechanical linkages, clevis pins, and shaft retention assemblies requiring a 5/8-inch shaft diameter fitment.

Installation Notes

Installation requires no special tools beyond standard pliers for seating the locking ring. Ensure the mating shaft diameter falls within the specified range before installation. Inspect the pin for deformation before reuse, as spring steel cotter pins are typically single-use fasteners. Follow applicable equipment manufacturer guidelines and any relevant mechanical codes when installing fasteners in safety-critical assemblies.
