Gibraltar KN5C----F7SB-22 Lobed Knob 8-point 2.48 in

Product Description

The GIBRALTAR KN5C----F7SB-22 is an 8-point lobed knob designed for manual adjustment and hand-tightening applications across industrial and mechanical equipment. The knob features a polypropylene inner core with a thermoplastic elastomer overmold, providing a firm grip surface with a matte black finish. The head measures 2.48 inches in diameter and 0.72 inches in height, with an overall height of 1.29 inches. The threaded hole accepts a 5/16-18 fastener with a thread depth of 0.55 inches. This hardware component is commonly installed by maintenance technicians, machine builders, and equipment assemblers.

This lobed knob is suited for use in industrial machinery, mechanical assemblies, and equipment enclosures where a tool-free hand-adjustable fastening point is needed. The 8-lobe profile distributes hand torque evenly, making it appropriate for panel doors, guards, jigs, fixtures, and adjustment mechanisms in both production and service environments. The thermoplastic elastomer overmold offers resistance to light oils and shop-floor contaminants encountered in typical trade settings.

Installation Notes

Installation requires no special tools — the knob is hand-tightened onto a 5/16-18 threaded stud or bolt. Verify the mating thread length does not exceed the 0.55-inch thread depth to avoid bottoming out. Ensure the mating surface is clean and free of debris before seating the knob. Power down or de-energize any equipment before accessing panel-mounted hardware.
