Gibraltar PKG-359-G Lobed Knob 63mm 7-point M12x1.75

Product Description

The GIBRALTAR PKG-359-G is a 7-point lobed knob designed for hand-operated adjustment and fastening applications in industrial, mechanical, and trade service environments. Constructed from thermoplastic elastomer, it provides a firm, comfortable grip without the need for tools. The knob features a 63 mm head diameter and a molded-in M12 x 1.75 threaded stem with a 25 mm thread length, making it a direct-fit hardware component for panels, enclosures, fixtures, and equipment access covers. Electricians, HVAC technicians, and mechanical service professionals commonly install this type of knob wherever tool-free manual adjustment or secure hand-tightening is required.

This lobed knob suits residential and commercial applications including control panel assemblies, equipment enclosures, jig and fixture setups, and service access points. The 7-lobe profile distributes hand pressure evenly, reducing fatigue during repeated adjustments. At 40 mm overall height, it fits shallow-clearance mounting locations without interfering with adjacent components. It is sold individually and is appropriate wherever an M12 x 1.75 threaded interface is present and hand operation is preferred over wrench-driven fasteners.

Installation Notes

Installation requires no special tools — thread the stem into a compatible M12 x 1.75 tapped hole by hand. De-energize or lock out any equipment before accessing panels or enclosures where this knob is being installed or replaced. Verify thread engagement of at least the full 25 mm thread length to ensure secure fastening. Do not use power tools to drive this knob, as over-torquing may damage the thermoplastic elastomer body.
