Gibraltar G10-3008-W Fluted Knob Phenolic Female Insert

Product Description

The GIBRALTAR G10-3008-W is a fluted knob with a 1-1/4 inch head diameter, designed for use as a hand-adjustment control in machinery, fixtures, and industrial equipment. The knob features a female threaded insert sized to accept a 1/4-20 fastener, making it compatible with standard machine screws and threaded rod. The body is molded from phenolic, a durable thermoset material that resists heat and mechanical wear. A glossy finish provides a clean appearance and smooth grip surface. This type of knob is typically installed by machine builders, maintenance technicians, and equipment fabricators.

Fluted knobs with female inserts are a standard hardware solution for hand-operated adjustment points on industrial machines, jigs, fixtures, panels, and enclosures. The 1/4-20 thread is one of the most common fastener sizes in light-duty machine hardware, making this knob a straightforward fit for new builds and replacement applications in shop, plant, and field environments. The phenolic construction holds up in environments with moderate heat exposure and light chemical contact, where plastic knobs would deform or degrade.

Installation Notes

Installation requires no tools beyond threading the knob onto a 1/4-20 screw or stud by hand. Confirm the mating thread is clean and undamaged before installation. Do not use power tools or excessive torque to drive the knob, as the phenolic body can crack under overload. This hardware is typically installed by maintenance technicians or machine builders during assembly or field service.
