Value Collection 22-100 Hair Pin Cotter 3/8-3/4 in Shaft

Product Description

The VALUE COLLECTION 22-100 is a hair pin cotter pin designed to secure shafts ranging from 3/8 inch to 3/4 inch in diameter. Constructed from Grade 302 18-8 stainless steel, this fastener resists corrosion and maintains holding strength in wet, outdoor, and chemically exposed environments. The pin measures 2-1/2 inches in length with a wire diameter of 0.093 inches, providing reliable retention across a range of shaft sizes. Maintenance technicians, millwrights, and field service professionals commonly use hair pin cotters as quick-release retaining fasteners on clevis pins, pivot assemblies, and linkage rods.

Hair pin cotter pins are widely used in HVAC equipment linkages, damper assemblies, pump shaft retainers, and general mechanical assemblies where a fast-install, reusable retaining fastener is required. The 3/8 to 3/4 inch shaft compatibility range makes this cotter suitable for light to medium industrial and commercial service applications. Each package contains 10 pieces, making it practical to stock for routine service calls and repair work.

Installation Notes

Installation and removal of hair pin cotter pins requires no special tools in most applications, though needle-nose pliers may assist with access in tight assemblies. Always de-energize and lock out equipment before servicing any shaft or linkage assembly. Inspect the pin for deformation or fatigue before reuse, and replace any pin that shows bending, cracking, or loss of spring tension. Follow applicable equipment manufacturer guidelines and relevant mechanical safety codes when servicing assemblies.
