The knob measures 1-5\/8 inches in diameter and 1-1\/2 inches in height, with a 1\/2-inch hole depth sized to accept a 3\/8-16 threaded stud or fastener. The smooth grip surface and black thermoplastic construction provide a durable, functional interface for machine guards, jigs, fixtures, and similar equipment. Technicians and maintenance professionals install this type of knob wherever a tool-free hand adjustment point is needed.\u003c\/p\u003e\n\u003cp\u003eThis ball knob is suited for light to medium-duty industrial and trade applications including machine tooling setups, enclosure hardware, clamp assemblies, and panel controls.
