Gibraltar ALH-29MTT-G Lobed Knob 4-point Aluminum M16x2

Product Description

The GIBRALTAR ALH-29MTT-G is a 4-point lobed knob machined from 6063-T5 aluminum, designed for hand-tightening and manual adjustment applications in industrial, mechanical, and light fabrication settings. With a head diameter of 76.2 mm and an M16x2 threaded stem, this knob provides a firm, ergonomic grip across all four lobes without the need for tools. The 6063-T5 aluminum construction keeps weight low while delivering adequate strength for repeated manual cycling in non-impact applications. It weighs approximately 0.22 pounds, making it practical for lightweight assemblies and panel-mount configurations.

This lobed knob suits a wide range of industrial and mechanical assembly scenarios, including jig and fixture work, machine guards, equipment panels, and adjustable clamping components. The M16x2 thread size makes it compatible with standard metric fastener systems found in manufacturing equipment, machine tools, and fabrication hardware. It is typically installed by maintenance technicians, machine builders, and fabricators who need a reliable hand-operated fastening solution on metric-threaded components.

Installation Notes

Installation is performed by hand threading the knob onto an M16x2 male-threaded stud or bolt. Ensure the mating thread is clean and free of debris before installation. Do not use power tools or impact drivers on this knob, as over-torquing can damage the aluminum hub. Confirm the assembly is de-energized or secured before adjusting any clamping or locking components on active equipment.
