Gibraltar LBR-118 Quick-release Pin 1/4 in 3.5 in Steel

Product Description

The GIBRALTAR LBR-118 is a button-handle quick-release pin machined from 4130 alloy steel with a zinc-plated finish. The pin measures 0.25 inches in diameter with a usable length of 3.5 inches. A spring-loaded button mechanism allows fast, tool-free removal and reinstallation, making it well suited for applications that require frequent disassembly or adjustment. The zinc plating provides a baseline level of corrosion resistance for general shop, industrial, and mechanical assembly environments. Machinists, maintenance technicians, and fabricators are the primary installers of this fastener type.

Quick-release pins of this type are used across a broad range of applications including jig and fixture assemblies, agricultural equipment, material handling frames, and industrial machinery where a removable pin connection is needed. The button-handle design is sized for manual actuation without tools, which suits production environments and field service situations alike. This pin ships as a single unit and is measured in the inch system of measurement.

Key Features

• Button-handle design allows tool-free, one-hand pin removal and insertion
• 0.25 inch pin diameter suits common clevis, bracket, and fixture hole patterns
• 3.5 inch usable length accommodates moderate panel or assembly stack thicknesses
• 4130 alloy steel construction provides good strength and wear resistance
• Zinc-plated finish offers corrosion resistance in general-duty environments
• Single-unit packaging; no minimum order above one piece

Compatibility

Designed as a standard inch-system quick-release pin for use in jigs, fixtures, agricultural equipment, and industrial machinery applications requiring a 0.25 inch diameter removable pin connection.

Installation Notes

Installation requires no special tools; align the pin with the mating hole and push until the button snaps into the locked position. Before servicing any machinery to replace or install this pin, de-energize equipment and relieve any stored mechanical tension or pressure in the assembly. Verify that the receiving hole diameter and stack length are compatible with the 0.25 inch diameter and 3.5 inch usable length before installation. Inspect the spring-loaded button mechanism for full engagement after installation to confirm the pin is properly retained.
