Value Collection C207-CPS3753500 Cotter Pin 3/8x3.5in Ss

Product Description

The VALUE COLLECTION C207-CPS3753500 is an extended prong cotter pin used to secure fasteners, clevis pins, shaft assemblies, and similar components against loosening or backing out. Machined from 18-8 stainless steel with a plain uncoated finish, this pin delivers reliable corrosion resistance in wet, outdoor, or chemically exposed environments. The extended prong design allows the legs to be bent back securely after insertion, locking the assembly in place. At 0.375 inches in diameter and 3.5 inches in length, it fits larger pin bores common in industrial, mechanical, and structural applications. Machinists, millwrights, pipefitters, and maintenance technicians working to ASME B18.8.1 standards will recognize this as a direct-fit, code-compliant fastener component.

This cotter pin is suited for use in mechanical assemblies where a positive locking method is required on clevis pins, castle nuts, or shaft retention applications. Typical install environments include industrial equipment, pump assemblies, structural brackets, and fluid-system linkages where vibration or dynamic loading could otherwise allow fasteners to back out. The plain finish is compatible with both dry and lubricated assemblies. Sold individually per package.

Key Features

• Extended prong design for secure leg bending and positive locking after installation
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Plain uncoated finish compatible with dry or lubricated assemblies
• Meets ASME B18.8.1 dimensional standards
• RoHS compliant

Compatibility

Designed as a standard ASME B18.8.1 extended prong cotter pin suitable for clevis pins, castle nuts, and shaft retention applications requiring a 0.375 inch bore diameter.

Installation Notes

Installation requires no special tools beyond standard needle-nose pliers for bending prongs after insertion. Ensure the mating pin bore is clear and properly aligned before driving the cotter pin through. Once installed, bend prongs in opposite directions or fold them back against the assembly to prevent withdrawal. Removal should be done with care to avoid damaging the bore or surrounding components; single-use replacement is recommended per standard maintenance practice.
