Gibraltar ALHA-6M-G Lobed Knob 4 Point Aluminum M10

Product Description

The GIBRALTAR ALHA-6M-G is a 4-point lobed knob machined from 6063-T5 aluminum alloy, designed for hand-tightening and manual adjustment applications in industrial, mechanical, and assembly environments. The knob features a 2.5 inch (63.5 mm) head diameter with four lobed grip points that provide secure tool-free torque. The M10 x 1.5 threaded stem extends 3 inch (76.2 mm), giving ample thread engagement for a wide range of fixture thicknesses. Weighing 0.2 pounds, this knob is a lightweight yet durable hardware component suited for jigs, fixtures, machine guards, and equipment panels.

This lobed knob is used wherever a secure, repeatable hand-tightened connection is needed without tools. Typical applications include clamping fixtures, enclosure latches, adjustment handles on production machinery, and panel fastening in industrial equipment. The aluminum construction keeps weight low while resisting corrosion in light-duty shop and manufacturing environments. Trades and technicians working in fabrication, equipment assembly, and maintenance will encounter this style of knob in frequent use across standard M10-threaded hardware setups.

Installation Notes

Installation is performed by hand-threading the M10 x 1.5 stem into a compatible tapped hole or threaded insert. Ensure the mating thread pitch and diameter match before assembly to avoid cross-threading. Do not use power tools or wrenches to drive or remove this knob, as over-torquing may damage the aluminum stem or the mating threads. Follow applicable equipment lockout/tagout procedures before servicing any assembly that incorporates this component.
