Gibraltar G10-0700 Fluted Tapered Phenolic Knob 3/8-16

Product Description

The GIBRALTAR G10-0700 is a counter-bored fluted tapered knob made from phenolic material, designed for use as a manual control or adjustment knob on machinery, equipment panels, and jigs. It features a 3/8-16 threaded hole with a depth of 0.5 inches, an overall length of 3 inches, a head diameter of 1.125 inches, and a base diameter of 0.625 inches. The black phenolic construction provides a firm, heat-resistant grip surface suited to industrial and shop environments. Machinists, machine builders, and equipment technicians install this type of knob to provide precise manual control on threaded shafts and fasteners.

This knob is a practical fit for light to medium-duty industrial applications including machine tool fixtures, panel controls, jig and fixture assemblies, and general-purpose equipment adjustment points. The fluted tapered profile gives operators a secure, comfortable grip without tools. The counter-bored mounting style allows the knob to seat flush or near-flush against a panel or surface, keeping the installation clean and snag-free. It is appropriate for indoor industrial and workshop environments where a durable, low-cost thermosetting plastic knob is preferred over metal hardware.

Installation Notes

Installation is performed by hand or with light tooling by machinists or equipment technicians. Before installing or replacing knobs on powered equipment, de-energize the machine and lock out the power source per applicable OSHA lockout/tagout procedures. Thread the knob onto the shaft by hand, ensuring full thread engagement to the 0.5-inch depth. Do not over-torque, as phenolic material can crack under excessive clamping force.
