Gibraltar LBH-129 Quick-release Pin 5/16 in 4130 Steel

Product Description

The GIBRALTAR LBH-129 is a quick-release pin with a ring handle, designed for fast, tool-free engagement and disengagement in mechanical assemblies, jigs, fixtures, and industrial equipment. The pin measures 5/16 inches in diameter with a 4-inch usable length and a 5.25-inch overall length. Constructed from 4130 alloy steel with a zinc-plated finish, it delivers solid corrosion resistance and strength suited to light industrial and maintenance applications. The ring handle allows for rapid single-hand operation without additional tooling, making it a reliable component for recurring adjustment points or removable subassemblies.

This quick-release pin is commonly used in fabrication shops, maintenance environments, and mechanical assembly applications where components need to be frequently removed or repositioned. It is appropriate for use in fixtures, carts, frames, guards, and other assemblies requiring a positive-locking removable pin. The inch-system dimensions make it a direct fit for standard inch-series bored holes and clevis-style connections found throughout general industrial and trade settings.
