Gibraltar G10-0033AP Ball Knob Female Insert M12x1.75

Product Description

The GIBRALTAR G10-0033AP is a red phenolic ball knob with a female insert mount designed for use on threaded machine components and control assemblies. The knob measures 1-3/8 inches in diameter and 1-9/32 inches in height, with an M12x1.75 female thread insert and a hole depth of 18 millimeters. The smooth grip surface and phenolic construction make it suitable for manual positioning, clamping, and adjustment applications in industrial and mechanical settings. It is installed by maintenance technicians and machine builders working on equipment requiring hand-operable knobs.

This ball knob is used in industrial machinery, jigs, fixtures, and mechanical assemblies where a hand-operated control point is needed. The female insert design allows it to thread directly onto a male-threaded shaft or stud. Its red color supports visual identification of controls or safety-critical adjustment points on equipment. The compact 5/8-inch hub diameter accommodates standard shaft sizes common in machine tool and industrial hardware applications.

Installation Notes

Installation is performed by hand or with standard hand tools. Verify the mating shaft or stud thread is M12x1.75 before installation to ensure proper engagement. Ensure the threaded stud is clean and free of damage before threading the knob on. Do not overtighten, as phenolic material can crack under excessive force.
