Gibraltar G10-0033AC Ball Knob Female Insert 1-3/8 in

Product Description

The GIBRALTAR G10-0033AC is a smooth-grip ball knob with a female insert mount designed for use on threaded shafts and fasteners in light mechanical, industrial, and equipment applications. The knob body is molded from phenolic, a durable thermoset material that resists moderate heat and common shop chemicals. It measures 1-3/8 inches in diameter and 1-9/32 inches in height, with a 7/16-20 threaded female insert and a hole depth of 3/4 inches. The red color aids visual identification in multi-knob panel or machine setups. Technicians and maintenance professionals use this style of knob wherever a tool-free hand-tightened grip point is needed.

This ball knob is suited for use on machine tools, control panels, jigs, fixtures, and general equipment requiring a hand-adjusted knob on a threaded stud or shaft. The female insert design threads directly onto an existing male stud. Typical applications include industrial machinery, HVAC equipment access panels, and mechanical control assemblies where a compact, smooth-grip knob is appropriate. The 5/8-inch hub diameter provides a defined seating surface against the mounting face.

Compatibility

Designed as an OEM-style replacement or aftermarket addition for any threaded application using a 7/16-20 male stud that requires a hand-tightened ball knob with a female insert mount.

Installation Notes

Installation requires no special tools — thread the knob onto the existing male stud by hand until seated firmly against the mounting surface. Ensure the mating stud thread is 7/16-20 and that the engaged thread length does not exceed the 3/4 inch hole depth. Disconnect or de-energize any associated equipment before replacing knobs on live control panels or powered machinery. Do not apply excessive torque, as phenolic bodies can crack under over-tightening.
