Gibraltar mqr-1057 Ball Lock Hitch Pin Zinc Plated Steel

Product Description

The GIBRALTAR mqr-1057 is a zinc plated steel ball lock hitch pin designed for quick, tool-free securing of clevis pins, yokes, and linkage assemblies in industrial and mechanical applications. The pin measures 0.25 inches in diameter and 2.5 inches in overall length, with a 2.25-inch usable length. A spring-loaded ball bearing locks the pin in place upon insertion and releases with a simple press, making it well suited for maintenance technicians and tradespeople who need fast, reliable pin retention without cotter pins or clips.

This ball lock hitch pin is commonly used in industrial equipment, agricultural machinery, material handling systems, and general mechanical linkage work. Its compact 0.25-inch diameter fits standard small-bore clevis and yoke fittings. The zinc plated finish provides basic corrosion resistance for both indoor and light outdoor use. It ships and is sold as a single unit.

Key Features

• Spring-loaded ball lock mechanism allows tool-free insertion and removal
• 0.25-inch pin diameter fits standard small-bore clevis and yoke fittings
• 2.25-inch usable length accommodates typical light-duty linkage thicknesses
• Zinc plated steel construction provides corrosion resistance for indoor and light outdoor environments
• Rockwell C 25-34 hardness rating for adequate shear and wear resistance in mechanical applications

Compatibility

Designed as an OEM-style replacement or standard service pin for mechanical linkage assemblies requiring a 0.25-inch diameter ball lock hitch pin with a 2.25-inch usable length.

Installation Notes

Installation requires no special tools — align the pin with the bore, press the ball detent inward, insert fully, and release to lock. Always ensure the receiving bore diameter matches the pin diameter before installation. Inspect the ball detent and spring function before each use in load-bearing or safety-critical applications. Depressurize or de-energize any associated equipment before servicing pin connections.
