Gibraltar PKG-358-G Lobed Knob 7-point 63mm Tpe M12x1.75

Product Description

The GIBRALTAR PKG-358-G is a 7-point lobed knob designed for tool-free manual adjustment and fastening in industrial, mechanical, and equipment assembly applications. The knob is molded from thermoplastic elastomer (TPE), which provides a firm yet comfortable grip surface that resists slipping during hand-tightening. It features an M12 x 1.75 threaded steel stem with 20 mm of usable thread length, allowing direct engagement with standard metric threaded inserts, studs, or tapped holes. The 63 mm head diameter distributes hand pressure across the lobed profile, reducing operator fatigue during repeated adjustments. Technicians across maintenance, automation, and light manufacturing environments commonly install this type of hardware as a replacement or upgrade from standard fasteners.

This lobed knob is suited for use wherever tool-free clamping, positioning, or adjustment is required. Typical applications include machine guards, jigs and fixtures, conveyor frames, equipment panels, and industrial enclosures. The M12 x 1.75 metric thread is a widely used coarse-pitch standard, making this knob compatible with a broad range of domestically and internationally manufactured equipment that uses metric fastening systems.

Key Features

• 7-lobe profile provides multiple finger engagement points for secure hand-tightening
• 63 mm head diameter for broad grip surface and reduced hand fatigue
• Thermoplastic elastomer (TPE) construction offers durability and tactile grip
• M12 x 1.75 metric coarse-pitch threaded stem for wide compatibility
• 20 mm thread length suits standard panel and fixture mounting depths
• 40 mm overall height keeps a low profile in space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or drop-in upgrade for applications requiring a 7-point lobed knob with an M12 x 1.75 threaded stem and 63 mm head diameter in industrial and mechanical assembly settings.

Installation Notes

Installation is typically performed by maintenance technicians or assembly personnel without special tools, as this knob is designed for hand-tightening. Ensure the mating threaded hole or stud is clean and free of debris before threading the knob on. Do not use power tools to drive the knob, as this can strip the TPE overmold or damage the threaded insert. Verify thread engagement depth is sufficient for the application load before placing equipment back into service.
