Gibraltar G10-0033AJ Ball Knob Female Insert Phenolic Black

Product Description

The GIBRALTAR G10-0033AJ is a phenolic ball knob with a female insert mount designed for use on threaded shafts, rods, and machine components. The knob accepts an M10 x 1.50 x 15 threaded insert and measures 1-3/8 inches in diameter with a height of 1-9/32 inches. The smooth grip surface and black phenolic construction make it a standard choice for panel controls, jigs, fixtures, and light industrial equipment where a secure hand-tightened fastening point is needed. Machinists, maintenance technicians, and equipment builders install this type of knob across a wide range of fabrication and assembly applications.

This ball knob is suited for use on machine tool controls, fixture clamps, adjustment levers, and industrial equipment panels in both shop and light manufacturing environments. The female insert style allows the knob to thread directly onto an existing male stud or bolt without requiring a separate stem. It is appropriate for applications where a compact, low-profile hand control is needed on a metric-threaded post or fastener.

Compatibility

Designed as a direct-thread female insert ball knob for use on M10 x 1.50 threaded male studs and bolts in machine tool, fixture, and industrial equipment applications.

Installation Notes

Installation requires no special tools — thread the knob onto a compatible M10 x 1.50 male stud by hand until snug. Ensure the mating stud or bolt does not exceed the 15 mm hole depth to avoid bottoming out the insert. Disengage or power down any associated equipment before replacing or repositioning knobs on control panels or moving machine components. Do not use impact tools or exceed hand-tight torque, as phenolic material can crack under excessive mechanical force.
