Value Collection C3505 Hair Pin Cotter Spring Steel

Product Description

The VALUE COLLECTION C3505 is a hair pin cotter designed to secure pins, axles, and shafts across a range of mechanical assemblies. It fits shaft diameters from 5/8 inch to 1 inch and measures 2-15/16 inches in length with a wire diameter of 0.149 inches. Manufactured from Grade 2 spring steel with a plain steel finish, it delivers the resilience and retention force required for reliable fastening in vibration-prone environments. This type of cotter pin is a standard component in HVAC equipment linkages, pump assemblies, blower shaft connections, and general mechanical installations where a quick, tool-free retention method is needed.

The C3505 hair pin cotter is suited for light to medium-duty shaft retention in residential and commercial mechanical systems. Common applications include securing clevis pins on damper linkages, blower wheel hubs, belt-drive components, and pump shaft assemblies. The spring-steel construction allows the pin to snap into position and resist backing out under normal operating vibration. It is sold in a package quantity of 25, making it practical to stock for routine service and repair work.

Installation Notes

Hair pin cotters are typically installed and removed by hand or with needle-nose pliers. Always de-energize equipment and relieve any mechanical tension on the shaft or linkage before removing or installing retention hardware. Inspect the pin seat and shaft groove for wear or burring before installing a new cotter. Follow applicable equipment manufacturer service procedures and relevant mechanical codes for the system being serviced.
