Gibraltar mrq-ss-1055 Ball Lock Hitch Pin 1/4 in Stainless

Product Description

The GIBRALTAR mrq-ss-1055 is a ball lock hitch pin designed for quick-connect and quick-release fastening applications across industrial, mechanical, and trade service environments. The pin measures 0.25 inches in diameter and 2.25 inches in total length, with 2 inches of usable length. Constructed from stainless steel with a zinc plated finish, it delivers corrosion resistance suitable for both indoor and outdoor use. A Rockwell C hardness rating of 25-34 confirms adequate toughness for load-bearing and alignment tasks where repeated removal and reinstallation are common.

This ball lock hitch pin is well suited for use in equipment maintenance, machinery fixtures, tooling setups, and general mechanical assemblies where a tool-free, positive-locking pin connection is required. Electricians, HVAC technicians, plumbers, and general maintenance professionals reach for this type of fastener when securing access panels, bracket assemblies, linkages, or portable equipment frames. Its compact size makes it appropriate for tight clearance applications in light-duty mechanical systems.

Key Features

• Ball lock retention mechanism allows tool-free installation and removal
• Stainless steel construction with zinc plated finish for corrosion resistance
• Rockwell C hardness of 25-34 for reliable load-bearing performance
• 0.25 inch pin diameter with 2 inches of usable length
• Compact 2.25 inch overall length suits tight clearance installations

Compatibility

Designed as a standard 0.25 inch diameter ball lock hitch pin suitable for use in general mechanical assemblies, equipment fixtures, and tooling applications requiring a quick-release locking pin.

Installation Notes

Installation requires no special tools — compress the ball lock mechanism, insert the pin through aligned holes, and release to engage the locking ball. Confirm hole diameter and material thickness match the pin diameter and usable length before installation. Inspect the ball lock mechanism for proper spring function before each use in load-bearing applications. Disengage any tension or load from the assembly before removing the pin.
