Value Collection 35209 Hair Pin Cotter 1/8 in Shaft

Product Description

The VALUE COLLECTION 35209 is a hair pin cotter designed to retain pins, shafts, and clevis pins in mechanical assemblies. Manufactured from Grade 2 spring steel with a plain steel finish, this cotter accepts a maximum shaft diameter of 1/8 inch, measures 3/4 inch in overall length, and is formed from 0.51-inch wire diameter stock. The spring steel construction provides the elasticity needed for secure retention and repeated installation and removal without deformation. Maintenance technicians, millwrights, and general mechanical tradespeople commonly use hair pin cotters in linkage assemblies, agricultural equipment, HVAC damper linkages, and light-duty mechanical connections.

This hair pin cotter is suited for residential and light commercial applications wherever a quick-release fastener is needed to lock a shaft or clevis pin in place. Typical install scenarios include HVAC actuator linkages, fan blade hubs, and pivot assemblies on equipment access panels. The compact 3/4-inch length fits confined mounting locations where standard cotter pins may be difficult to bend or remove. Sold in a package quantity of 50, making it practical for service vans and shop stock.

Installation Notes

Hair pin cotters are installed and removed by hand or with needle-nose pliers. Always relieve any load on the pin or shaft before inserting or removing the cotter to prevent the cotter from launching free. Inspect the cotter for deformation or fatigue cracks before reuse. Discard any cotter that does not spring back to its original shape after removal.
