Gibraltar LBH-127 Quick-release Pin 5/16 in 3 in 4130 Steel

Product Description

The GIBRALTAR LBH-127 is a ring-handle quick-release pin machined from 4130 alloy steel with a zinc-plated finish. The pin measures 5/16 inches in diameter with a 3-inch usable length and a 4.25-inch overall length. Quick-release pins are used to secure, align, or retain components in assemblies where frequent removal is required without tools. The ring handle allows fast one-handed operation. The 4130 steel construction provides solid tensile strength for industrial and mechanical applications. This type of fastener is installed by maintenance technicians, millwrights, and fabricators working on jigs, fixtures, machine guards, and structural connections.

This pin is suited for use in industrial machinery, fabrication fixtures, agricultural equipment, and general mechanical assemblies where a removable retention pin is required. Its inch-system dimensions make it a direct fit for standard inch-series pin holes at 5/16 inches. The zinc-plated finish offers basic corrosion resistance for indoor and light-duty outdoor environments. Applications typically include locking hinged panels, securing clevis connections, and retaining adjustable components on frames or structures.

Compatibility

Designed as an OEM-style or aftermarket replacement quick-release pin for inch-series applications requiring a 5/16-inch diameter retention pin with a 3-inch usable length.

Installation Notes

Installation requires no special tools; insert the pin through aligned bores and allow the spring-loaded detent to seat fully before releasing. Always verify the bore diameter and required usable length match the application before installation. Depressurize, de-energize, or relieve load on the assembly before removing or inserting the pin to prevent unintended movement. Inspect the detent mechanism and pin shank for wear or deformation during routine maintenance.
