Gibraltar LBT-129 Quick-release T-handle Pin 5/16 in

Product Description

The GIBRALTAR LBT-129 is a quick-release T-handle pin designed for fast, tool-free insertion and removal in mechanical assemblies, fixtures, and positioning applications. Manufactured from 4130 steel with a zinc-plated finish, this pin resists corrosion and handles repeated use in industrial and trade environments. The T-handle provides a secure grip for manual actuation without additional hardware. At 5/16 inch in diameter and 4 inches of usable length, it suits a wide range of medium-duty fastening and alignment tasks across fabrication, maintenance, and equipment assembly applications.

This pin is commonly used in jig and fixture setups, equipment panels, guards, and mechanical linkages where quick access and repositioning are required. The zinc-plated 4130 steel construction makes it appropriate for both shop-floor fabrication environments and light-duty field maintenance scenarios. It is installed and used by machinists, millwrights, maintenance technicians, and general tradespeople working with positioning or alignment hardware.

Installation Notes

Installation requires no special tools. Verify that the receiving hole diameter matches the 5/16 inch pin diameter before installation to ensure proper fit and retention. Inspect the quick-release mechanism for wear or deformation periodically, especially in high-cycle applications. Replace if the locking detent does not engage fully or if visible damage to the pin or handle is present.
