The knob measures 1.88 inches in diameter and 1.75 inches in height, offering a comfortable grip profile for hand-tightening tasks. The female insert accepts a 3\/8-16 thread and provides a hole depth of 0.55 inches, making it suitable for standard fastener engagement. The black thermoplastic construction resists corrosion and handles routine shop and field conditions without degradation.\u003c\/p\u003e\n\u003cp\u003eThis ball knob is well suited for use on machinery guards, equipment enclosures, panel latches, jigs, fixtures, and adjustment handles found in HVAC, electrical, plumbing, and general mechanical service environments.
