Gibraltar LBR-117 Quick-release Pin 1/4 in 3 in 4130 Steel

Product Description

The GIBRALTAR LBR-117 is a quick-release pin with a button handle, designed for fast, tool-free insertion and removal in mechanical assemblies, fixtures, and industrial applications. The pin is manufactured from 4130 alloy steel with a zinc-plated finish for corrosion resistance. It measures 0.25 inches in diameter with a 3-inch usable length. The button-handle release mechanism allows single-hand operation, making it well-suited for applications where frequent disassembly or adjustment is required. Machinists, fabricators, maintenance technicians, and industrial assembly personnel are the primary installers and users of this type of hardware.

This quick-release pin is used in jigs, fixtures, tooling setups, and general industrial machinery where a positive-locking, easily removable pin is needed. It is appropriate for both light production environments and maintenance applications where components must be swapped or repositioned regularly. The inch-measurement system and standard 0.25-inch diameter make it compatible with a wide range of commercially available clevis mounts, brackets, and fabricated assemblies that call for this pin diameter.

Key Features

• Button-handle release allows single-hand, tool-free removal
• 4130 alloy steel construction for strength in load-bearing pin applications
• Zinc-plated finish provides corrosion resistance in typical shop and industrial environments
• 0.25-inch pin diameter suits a wide range of standard clevis and bracket applications
• 3-inch usable length accommodates moderate material stack-up in assemblies
• Packaged as a single unit — order quantity matches usage without surplus

Compatibility

Designed as a standard quick-release pin replacement or new installation for industrial fixtures, jigs, and mechanical assemblies requiring a 0.25-inch diameter, 3-inch usable length button-handle pin in inch-measurement applications.

Installation Notes

Installation requires no special tools — insert the pin through aligned holes in mating components and verify the button-release mechanism seats fully before applying load. Ensure the receiving hole diameter matches the 0.25-inch pin diameter with appropriate clearance to prevent binding or excessive slop. Inspect the spring-loaded release mechanism periodically for debris or deformation that could prevent full engagement. Do not exceed the load ratings appropriate for 4130 steel pins of this diameter; consult engineering references when using in load-critical assemblies.
