Gibraltar ALHA-1M-G Lobed Knob Aluminum M6x1

Product Description

The GIBRALTAR ALHA-1M-G is a 4-point lobed knob machined from 6063-T5 aluminum. It features a 38.1 mm head diameter and an M6 x 1 threaded stem with a 44.5 mm thread length. The lobed profile provides a secure, tool-free grip for hand-tightening and adjustment applications. At 0.07 pounds, this lightweight fastener component is suited for equipment panels, jigs, fixtures, and mechanical assemblies where frequent manual adjustment is required. Machinists, maintenance technicians, and equipment builders commonly specify this type of knob for industrial and trade service applications.

This lobed knob is used in light-duty to medium-duty clamping and positioning applications across industrial equipment, HVAC enclosures, panel assemblies, and fabricated fixtures. The aluminum construction keeps weight low while resisting corrosion in typical indoor service environments. The M6 x 1 stem thread is a standard metric size, making it compatible with a wide range of threaded inserts, studs, and threaded holes found in sheet metal panels and aluminum extrusions.

Key Features

• 4-point lobed profile for reliable hand-grip without tools
• 38.1 mm head diameter provides adequate torque leverage for panel adjustments
• M6 x 1 threaded stem in 44.5 mm thread length accommodates varying stack depths
• 6063-T5 aluminum construction — lightweight and corrosion-resistant
• Compact and lightweight at 0.07 pounds, suitable for weight-sensitive assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit component for assemblies using M6 x 1 threaded fastener points, including panel enclosures, fixtures, and adjustment mechanisms that accept standard metric lobed knobs.

Installation Notes

Installation requires no special tools — thread the M6 x 1 stem into the mating threaded hole or insert by hand. Verify thread engagement covers the full working length before applying operational loads. De-energize or shut down any equipment before replacing or repositioning knobs on live assemblies. Do not overtighten beyond hand-snug torque, as aluminum threads can strip under excessive force.
