Value Collection MP38226-1 Hammerlock Cotter Pin

Product Description

The VALUE COLLECTION MP38226-1 is a hammerlock cotter pin used to secure clevis pins, linkage rods, and pivot assemblies in mechanical and light industrial applications. Manufactured from Grade 2 steel with a zinc-plated finish, it measures 0.109 inches in diameter and 1.75 inches in length. The hammerlock design allows the looped end to be bent back over the pin shaft after insertion, creating a positive lock that resists vibration-induced loosening. Technicians and maintenance professionals in HVAC, plumbing, and general mechanical trades use these pins when servicing damper linkages, valve actuators, and bracket assemblies.

This cotter pin suits residential and light commercial applications where a compact, corrosion-resistant fastener is needed to retain pins in clevis or rod-end connections. The zinc plating provides baseline protection against oxidation in indoor and sheltered outdoor environments. At 0.109 inches diameter and 1.75 inches length, it fits a wide range of standard clevis and linkage pin diameters common in HVAC damper control, sheet metal fabrication, and mechanical equipment assemblies.

Key Features

• Hammerlock style for positive mechanical retention after installation
• Grade 2 steel construction for reliable performance in standard-duty fastening
• Zinc-plated finish provides corrosion resistance in typical indoor environments
• Compact 0.109 inches diameter fits standard clevis and linkage pin slots
• 1.75 inches length accommodates typical clevis pin shaft depths

Compatibility

Designed as a standard-duty hammerlock cotter pin for use in clevis pin, linkage rod, and pivot assembly applications requiring a 0.109-inch-diameter retaining pin.

Installation Notes

Installation requires no special tools beyond needle-nose pliers to bend the hammerlock end into place after the pin is seated through the clevis hole. Ensure the assembly is de-energized and depressurized before servicing any linkage or actuator components. The looped end must be fully bent flush against the shaft to achieve proper retention. Do not reuse a cotter pin that has been removed, as repeated bending compromises material integrity.
