It features a 1.75-inch head diameter and a 0.99-inch overall height, making it a compact, lightweight fastening component suited for hand-adjustment applications. The knob accepts a 3\/8-inch stem and delivers a comfortable grip surface across all five points. Weighing 0.4 pounds, it is designed for repeated manual operation in equipment panels, enclosures, jigs, fixtures, and other industrial or mechanical assemblies. Technicians and tradespeople use this type of knob anywhere tool-free adjustment or clamping is required.\u003c\/p\u003e\u003cp\u003eThis star knob is appropriate for use in light-duty to medium-duty hand-tightening applications across HVAC equipment panels, electrical enclosures, machine guards, and shop fixtures. The polypropylene construction resists corrosion and is suitable for dry and mildly humid environments. Its 3\/8-inch hole size fits standard threaded inserts and bolts commonly found in fabricated steel and aluminum assemblies, making it a practical replacement or upgrade for worn or missing knobs on existing equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-point star profile provides secure grip for hand tightening without tools\u003c\/li\u003e\n\u003cli\u003e1.75-inch head diameter for comfortable thumb-and-finger operation\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hole size fits standard threaded fasteners\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction resists corrosion in dry and mildly humid environments\u003c\/li\u003e\n\u003cli\u003eMatte black finish reduces glare and conceals surface wear\u003c\/li\u003e\n\u003cli\u003eCompact 0.99-inch overall height suits low-clearance panel and fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand knob replacement for equipment panels, enclosures, jigs, and fixtures using 3\/8-inch threaded fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis knob is installed by a technician or mechanical assembler by threading it onto an existing 3\/8-inch stud or bolt by hand.
