Value Collection C207-BP2104 Hair Pin Cotter 5/16-3/8 in

Product Description

The VALUE COLLECTION C207-BP2104 is a hair pin cotter designed to secure pins, shafts, and fasteners in place across a wide range of mechanical and industrial applications. Sized for shaft diameters from 5/16 to 3/8 inches, this cotter measures 1-7/16 inches in length with a wire diameter of 0.073 inches. Manufactured from Grade 2 spring steel with a zinc-plated finish, it delivers the spring tension and corrosion resistance required for reliable retention in both indoor and light outdoor environments. Maintenance technicians, millwrights, and general tradespeople reach for this style of fastener when a quick-install, reusable locking solution is needed on clevis pins, shaft ends, and linkage assemblies.

This hair pin cotter is suited for use in HVAC linkage assemblies, plumbing equipment brackets, pump and motor shaft connections, and general mechanical installations where a positive-retention fastener is needed without the use of tools. Its spring-steel construction allows it to snap into place and stay seated under vibration, making it appropriate for both stationary and lightly dynamic load conditions in residential and light commercial equipment service.

Key Features

• Fits shaft diameters from 5/16 to 3/8 inches for versatile fitment across common pin and shaft sizes
• Wire diameter of 0.073 inches provides consistent spring tension and positive retention
• Grade 2 spring steel construction resists deformation under repeated installation and removal
• Zinc-plated finish offers corrosion resistance in light-moisture environments
• 1-7/16 inch overall length suits standard clevis pin and linkage applications
• Tool-free installation and removal speeds up service and maintenance work

Compatibility

Designed as a standard hair pin cotter for use with clevis pins and shafts in the 5/16 to 3/8 inch diameter range, suitable for general mechanical, HVAC, plumbing, and equipment maintenance applications.

Installation Notes

Hair pin cotters are installed and removed by hand without special tools. Ensure the shaft or pin hole is clean and free of burrs before seating the cotter to avoid distorting the wire. Always verify the cotter is fully seated and the legs are clear of rotating components before returning equipment to service. Inspect the cotter for deformation or corrosion during routine maintenance intervals and replace if spring tension is reduced.
