Value Collection MP35201 Hair Pin Cotter Spring Steel

Product Description

The VALUE COLLECTION MP35201 is a hair pin cotter designed to secure pins, shafts, and clevis fasteners in light mechanical assemblies. It accepts a maximum shaft diameter of 1/8 inch, measures 19/32 inch in overall length, and is formed from 0.295-inch wire diameter Grade 2 spring steel with a plain steel finish. The spring-steel construction provides the tension needed to stay seated under vibration and repeated removal cycles. Technicians across HVAC, plumbing, and general mechanical service use hair pin cotters to retain linkage pins, clevis pins, and similar fasteners in control linkages, damper assemblies, and bracket hardware.

This cotter is suited for light-duty retention applications in residential and commercial mechanical systems. Typical uses include securing clevis pins on gas valve linkages, damper actuator arms, pump bracket assemblies, and similar low-stress pin connections. The compact 19/32-inch length and 1/8-inch shaft capacity make it appropriate for the small-diameter pins common in HVAC control linkages and plumbing fixture hardware. Sold in a package quantity of 25, making it practical to stock for repeat service calls.

Key Features

• Maximum shaft diameter of 1/8 inch fits small clevis and linkage pins common in mechanical systems
• Grade 2 spring steel construction provides consistent retention force and resists fatigue from repeated installations
• 0.295-inch wire diameter for adequate stiffness in light-duty pin retention
• Plain steel finish suitable for interior mechanical and protected environments
• 19/32-inch overall length designed for standard light-duty cotter pin applications
• Package quantity of 25 supports stocking for multiple service calls

Compatibility

Designed as an OEM-style replacement or service stock cotter for light mechanical assemblies requiring 1/8-inch maximum shaft diameter hair pin retention.

Installation Notes

Hair pin cotters are installed and removed by hand or with needle-nose pliers — no special tools are required. Always inspect the mating pin for burrs or corrosion before installation, as surface damage can prevent the cotter from seating fully. Disengage or de-energize any actuator or linkage before removing or replacing a cotter pin to prevent unexpected movement. Replace the cotter if the spring leg shows permanent deformation or loss of tension.
