Constructed from cast iron with a zinc finish, this knob provides a firm, durable grip for operators adjusting equipment by hand. The head measures 2 inches in diameter, making it easy to grip and turn under normal working conditions. The 3\/8-16 threaded stem allows straightforward mounting to compatible shafts and threaded fasteners. Machinists, maintenance technicians, and equipment assemblers typically install this type of knob during machine setup or component replacement.\u003c\/p\u003e\u003cp\u003eThis spoked knob is suited for use on machine controls, jigs, fixtures, and industrial equipment where a sturdy hand-adjustable control point is required. The cast iron construction holds up in shop environments subject to oil, grit, and repeated handling. The 4-spoke design distributes grip load evenly and provides multiple contact points for turning leverage. It is appropriate for both original equipment assembly and field replacement on industrial machinery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast iron construction with zinc finish for durability in shop environments\u003c\/li\u003e\n\u003cli\u003e2 inch head diameter for comfortable hand grip\u003c\/li\u003e\n\u003cli\u003e4-point spoked design provides even grip distribution and turning leverage\u003c\/li\u003e\n\u003cli\u003e3\/8-16 threaded stem for standard threaded shaft mounting\u003c\/li\u003e\n\u003cli\u003e3\/4 inch hub diameter for solid engagement at the mounting interface\u003c\/li\u003e\n\u003cli\u003e1-1\/8 inch overall height for a low-profile control footprint\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install spoked knob for industrial machinery, fixtures, and equipment using a 3\/8-16 threaded stem interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by maintenance technicians or machine assemblers.
