Value Collection P20003 Locking Cotter Pin 0.25 in Shaft

Product Description

The VALUE COLLECTION P20003 is a locking cotter pin designed to secure fastener assemblies against loosening from vibration, rotation, or axial load. It features a 0.25 inch shaft diameter and a wire diameter of 0.054 inches, with an overall length of 0.936 inches. The pin is manufactured from RC 60-70 rated spring steel for consistent retention force and resistance to deformation. A zinc-plated finish provides basic corrosion protection in general-service environments. This style of cotter pin is installed by inserting the pin through a drilled shaft or clevis pin and bending or locking the ring end to prevent withdrawal. Mechanics, millwrights, and maintenance technicians across HVAC, plumbing, and industrial trades use this hardware type for linkage and actuator retention.

The P20003 is suited for light- to medium-duty fastening applications where a reusable or semi-permanent locking cotter is specified. Typical installations include control linkages, clevis joints, valve actuator rods, and threaded shaft retention in both residential and light commercial mechanical systems. The ring diameter range of 0.26 to 0.27 inches accommodates standard drilled-shaft tolerances at the 0.25 inch nominal shaft size. This part is sold individually per package unit with a minimum order quantity of 100 pieces per order.

Key Features

• 0.25 inch shaft diameter fits standard drilled clevis and actuator pin applications
• 0.054 inch wire diameter with RC 60-70 spring steel construction for reliable retention force
• Ring diameter range of 0.26 to 0.27 inches for consistent fit on standard shaft tolerances
• Overall length of 0.936 inches suits compact linkage and actuator rod assemblies
• Zinc-plated finish offers corrosion resistance in general indoor and sheltered service conditions
• UNSPSC Code 31163204 for procurement and catalog classification compliance

Compatibility

Designed as a standard locking cotter pin for use in mechanical assemblies requiring a 0.25 inch nominal shaft diameter with a ring diameter of 0.26 to 0.27 inches. Verify drilled-hole diameter and shaft clearance against application specifications before installation.

Installation Notes

Installation is typically performed by maintenance technicians or mechanics during linkage assembly or actuator rod service. Ensure the receiving shaft hole is clear of debris and that the shaft or clevis pin is fully seated before inserting the cotter pin. Do not reuse a cotter pin that has been bent, deformed, or fatigued during a previous installation. Follow applicable equipment manufacturer guidelines and relevant mechanical codes for fastener retention in your jurisdiction.
