Gibraltar G10-0145-C Ball Knob Female Insert 1-3/8 in

Product Description

The GIBRALTAR G10-0145-C is a phenolic ball knob with a female insert mount designed for use on machine handles, jigs, fixtures, and general industrial equipment. The knob measures 1-3/8 inches in diameter and 1-3/8 inches in height, with a smooth grip surface and a black finish. It accepts a 3/8-16 threaded insert with a hole depth of 1/2 inch, making it compatible with standard machine screws and threaded studs of that size. This knob is a common hardware component installed by machinists, millwrights, and equipment technicians during assembly, adjustment, or replacement of manual control points on machinery.

The G10-0145-C is suited for light to medium industrial applications where a hand-tightened grip point is needed. Typical installations include machine tool tables, drill press depth stops, fence adjustments, and fixture clamping arms. The smooth ball profile allows comfortable hand operation without sharp edges. The phenolic construction provides durability and resistance to oils and shop fluids commonly encountered in production environments.

Installation Notes

Installation is performed by threading the knob onto a 3/8-16 stud or screw by hand or with light tooling. Before replacing a knob on powered equipment, de-energize the machine and follow applicable lockout/tagout procedures per OSHA 1910.147. Do not exceed the recommended torque for the mating thread, and ensure the stud does not bottom out beyond the 1/2 inch hole depth to avoid cracking the insert.
