Value Collection P20290 Hair Pin Cotter Pin Stainless

Product Description

The VALUE COLLECTION P20290 is a hair pin cotter pin used to secure clevis pins, axles, and shafts in light mechanical assemblies. It accepts a maximum shaft diameter of 0.125 inches and measures 0.594 inches in overall length. The wire diameter is 0.03 inches. Manufactured from Grade 302 18-8 stainless steel, the P20290 resists corrosion and mild chemical exposure, making it suitable for both indoor and outdoor service environments. Machinists, millwrights, and maintenance technicians install these fasteners when a quick-release retaining solution is needed without tools.

Hair pin cotter pins of this size are commonly used in light-duty mechanical linkages, control arms, clevis assemblies, and pivot joints across HVAC equipment, plumbing fixture hardware, pool equipment linkages, and general industrial machinery. The open-loop design allows rapid installation and removal by hand, which is useful in service situations where frequent disassembly is required. This part is sold individually but is subject to a minimum order quantity of 100 pieces per order.

Installation Notes

Hair pin cotter pins are installed and removed by hand or with needle-nose pliers. Before servicing any assembly, de-energize the system and relieve any mechanical tension or pressure on the linkage. Ensure the shaft groove or hole is clean and free of burrs before inserting the pin to prevent premature fatigue or deformation of the wire.
