Gibraltar G10-0025 Ball Knob Threaded Hole 1.25in Phenolic

Product Description

The GIBRALTAR G10-0025 is a phenolic ball knob with a threaded hole mount, designed for manual adjustment and control applications across industrial, mechanical, and equipment assembly environments. The knob measures 1.25 inches in diameter and 1.25 inches in height, with a 1/4-20 threaded hole and a hole depth of 0.625 inches. Phenolic construction provides durability and resistance to moderate heat and solvents, making this knob suitable for repeated hand-tightening use. A smooth grip surface and compact hub diameter of 0.531 inches make it a reliable choice for tight-clearance installations. HVAC technicians, equipment assemblers, and maintenance professionals commonly install this type of hardware.

This ball knob is used wherever a threaded hand-adjustment point is needed on machinery, panel assemblies, HVAC equipment housings, plumbing fixtures, or general mechanical assemblies. The 1/4-20 stem engagement and 0.625-inch hole depth provide secure thread engagement for standard 1/4-20 fastener applications. Its black phenolic finish blends with most equipment aesthetics and withstands typical shop and field environments. It is sold individually but carries a minimum order quantity of 10 units, making it appropriate for service stock, small batch production, or equipment refurbishment projects.

Compatibility

Designed as a standard threaded-hole ball knob for equipment and assemblies using 1/4-20 threaded fastener interfaces. Suitable for use in HVAC, mechanical, and general industrial applications where a 1/4-20 threaded hand-control knob is required.

Installation Notes

Installation requires no special tools — thread the knob onto a compatible 1/4-20 stud or bolt by hand to the appropriate engagement depth within the 0.625-inch hole depth limit. Avoid over-torquing, as phenolic material can crack under excessive force. Ensure the mating threaded fastener is clean and free of debris before installation. Power down or de-energize any equipment before servicing panels or assemblies where this knob is being installed or replaced.
