Value Collection MP38229 Hammerlock Cotter Pin

Product Description

The VALUE COLLECTION MP38229 is a hammerlock cotter pin used to secure clevis pins, shafts, and fastening assemblies in light-duty mechanical applications. Manufactured from Grade 2 steel with a zinc-plated finish, this pin measures 0.125 inches in diameter and 1 inch in usable length. The zinc plating provides basic corrosion resistance suitable for indoor and sheltered environments. Installers in HVAC, plumbing, pool equipment, and general mechanical trades use hammerlock cotter pins to retain pins and linkage components where quick installation and positive locking are needed.

This cotter pin is suited for light-to-medium mechanical assemblies where a compact, reliable retention fastener is required. Typical applications include linkage rods, clevis assemblies, and pivot pin retention in equipment panels, damper actuators, valve linkages, and similar mechanical connections. The hammerlock style allows for faster installation compared to traditional hairpin cotter styles, making it practical in field service and maintenance scenarios.

Key Features

• Hammerlock style for quick, positive pin retention
• Grade 2 steel construction for light-duty mechanical use
• Zinc-plated finish for basic corrosion resistance
• 0.125 inch diameter fits standard clevis and shaft pin bores
• 1 inch usable length suitable for thin to mid-thickness assemblies

Compatibility

Designed as a general-purpose hammerlock cotter pin for use in light-duty mechanical linkage and clevis pin retention applications across HVAC, plumbing, and equipment maintenance contexts.

Installation Notes

Installation is performed by hand or with standard needle-nose pliers; no special tooling is required. Always de-energize and lock out any equipment before servicing linkage or pivot components. Inspect the pin bore for burrs or damage before insertion to ensure a secure fit. Replace the cotter pin any time the retained assembly is disassembled, as reuse can compromise locking integrity.
