Gibraltar ALHA-7M-G Lobed Knob 4-point Aluminum M12x1.75

Product Description

The GIBRALTAR ALHA-7M-G is a 4-point lobed knob machined from 6063-T5 aluminum, designed for use as a hand-tightened fastening control on industrial equipment, fixtures, and adjustable assemblies. With a 63.5 mm head diameter and an M12 x 1.75 threaded stem, this knob provides firm, tool-free grip adjustments in applications where frequent repositioning is required. The aluminum construction keeps weight low while delivering adequate strength for light-to-medium clamping loads. At 0.23 pounds, it is lightweight enough for panel-mounted or overhead installations. Machinists, maintenance technicians, and equipment assemblers install this type of knob as a standard hardware component across a wide range of industrial and commercial settings.

This lobed knob is suited for use on machine tools, jigs, fixtures, enclosures, and adjustable mechanical assemblies where hand operation without a wrench is preferred. The 4-point lobe profile distributes finger load evenly and allows confident torque application even with gloves. The M12 x 1.75 thread is a standard metric coarse-pitch size, making it compatible with a broad range of threaded inserts, studs, and threaded bores found in industrial fabrication and equipment maintenance environments. The 44.5 mm thread length accommodates varying stack thicknesses in typical mounting configurations.

Key Features

• 4-point lobed profile for ergonomic, tool-free hand tightening
• 63.5 mm head diameter provides a wide grip surface for controlled torque
• 6063-T5 aluminum construction — lightweight and corrosion-resistant
• M12 x 1.75 metric coarse-pitch threaded stem for broad compatibility
• 44.5 mm thread length accommodates varying material stack heights
• Weighs 0.23 pounds — suitable for weight-sensitive panel and fixture installations

Compatibility

Designed as a standard metric hardware component for use in any assembly, fixture, or equipment application requiring an M12 x 1.75 threaded hand knob.

Installation Notes

Installation is performed by hand or with light tooling by maintenance technicians, machinists, or equipment assemblers. Confirm the mating thread is M12 x 1.75 before installation to avoid cross-threading. Do not exceed the hand-tightening torque capacity of the aluminum stem — use a thread insert if higher clamping loads are required. Inspect the threaded bore for damage or debris before engaging the knob.
