Gibraltar LBR-141 Quick-release Pin 1/2 in 4130 Steel

Product Description

The GIBRALTAR LBR-141 is a button-handle quick-release pin machined from 4130 alloy steel and finished with a zinc-plated coating for corrosion resistance. It features a 1/2 inch pin diameter and a 1 inch usable length, making it suited for light-duty to medium-duty fastening applications where rapid manual disassembly is required. The button-release mechanism allows the locking balls or detents to retract without tools, enabling fast removal and reinsertion in fixtures, jigs, guards, or assemblies. Fabricators, maintenance technicians, and industrial mechanics commonly use this pin where frequent component removal is part of the workflow.

This pin is appropriate for use in industrial machinery guards, tooling fixtures, agricultural equipment linkages, and fabricated steel assemblies where a secure but removable connection is needed. Its inch-system dimensions suit standard American tooling setups. The zinc-plated finish provides a baseline level of protection against light moisture and oxidation in shop or field environments. Package quantity is one pin per order.

Key Features

• Button-handle design allows tool-free release and reinsertion
• 4130 alloy steel construction for strength in mechanical fastening applications
• Zinc-plated finish provides corrosion resistance in general shop environments
• 1/2 inch pin diameter fits common fixture and jig bore sizes
• 1 inch usable length suits shallow-to-standard engagement depths
• Inch measurement system for compatibility with standard American tooling

Compatibility

Designed as an OEM-style or replacement quick-release pin for industrial fixtures, machine guards, and fabricated assemblies requiring a 1/2 inch diameter button-handle pin with 1 inch of usable engagement length.

Installation Notes

Installation is performed by hand — no special tools are required for insertion or release. Ensure the receiving bore diameter and depth match the pin specifications before installation. Inspect the pin and bore for burrs or debris that could prevent full engagement of the locking mechanism. This pin should not be used in dynamic load applications or as a primary structural fastener unless the assembly design specifically accounts for quick-release pin ratings.
