Gibraltar mrq-ss-1045 Ball Lock Hitch Pin 1/4 in Stainless

Product Description

The GIBRALTAR mrq-ss-1045 is a ball lock hitch pin designed for quick-release fastening applications in industrial, agricultural, and mechanical assembly work. The pin measures 0.25 inches in diameter and 1.25 inches in total length, with 1 inch of usable length for engagement. Constructed from stainless steel with a zinc plated finish, it delivers corrosion resistance suited to both indoor and outdoor environments. The ball lock mechanism allows tool-free insertion and removal, making it a practical choice for any application requiring frequent disassembly or adjustment. Hardness is rated at Rockwell C 25-34, giving it solid resistance to wear under repeated cycling.

This pin is commonly used in light mechanical assemblies, linkages, clevis connections, fixtures, and equipment attachments where a secure but removable fastener is needed. Typical installation scenarios include securing levers, pedals, linkage rods, and hinged components on machinery, trailers, and shop fixtures. Suitable for both professional tradespeople and maintenance technicians working across manufacturing, agricultural equipment, and general mechanical service applications.

Compatibility

Designed as a standard 0.25 inch diameter ball lock hitch pin for use in clevis pins, linkage assemblies, and mechanical fixtures that accept this pin diameter and usable length.

Installation Notes

Installation requires no tools — compress the ball detent, insert the pin through the aligned holes, and release to lock. Always confirm hole diameter and material thickness match the pin diameter and usable length before installation. Inspect the ball detent mechanism before each use to ensure it seats fully and retains the pin under load. Do not substitute this pin in applications requiring a shear pin or cotter-style retainer unless the design specifications explicitly allow it.
