Gibraltar G10-3045-G 3 Arm Knob 2.5in 5/16-18 Black

Product Description

The GIBRALTAR G10-3045-G is a three-arm control knob manufactured from textured coated thermoplastic for a firm, non-slip grip in hand-tightening applications. The knob measures 2.5 inches in head diameter and 1.25 inches in height, with a hub diameter of 0.8125 inches. It uses a through-hole female insert style with a 5/16-18 threaded hole and a 0.5 inch hole depth. The black textured finish provides consistent appearance and grip across mechanical assemblies, panel controls, and equipment enclosures. Technicians and assemblers in HVAC, electrical, and general industrial settings use this type of knob wherever a tool-free adjustment or fastening point is needed.

This knob is suited for use on control panels, equipment enclosures, jigs, fixtures, and machinery requiring frequent manual adjustment. The 5/16-18 thread size is a standard inch-series coarse thread, making it compatible with a wide range of threaded inserts, studs, and bolts used in light-duty industrial and trade equipment assemblies. The textured thermoplastic construction handles typical indoor service environments without corrosion concern.

Installation Notes

Installation requires no special tools — thread the knob onto a 5/16-18 stud or bolt by hand until snug. Verify the mating stud length does not exceed the 0.5 inch hole depth to avoid bottoming out before the assembly is secure. Thermoplastic knobs are not rated for high-torque power-tool installation; apply hand force only to avoid cracking the insert or hub.
