Cast from iron with a zinc finish, it delivers durable grip and reliable torque transfer in demanding shop, factory, and mechanical service environments. The knob features a 2.5-inch head diameter and a 1\/2-13 threaded stem hole, making it compatible with standard 1\/2-13 threaded shafts and control stems. Licensed trades and maintenance technicians install this type of hardware on equipment requiring frequent manual adjustment without tools.\u003c\/p\u003e\n\u003cp\u003eThis spoked knob is suited for use on industrial machinery, valve actuators, jigs, fixtures, and mechanical assemblies where a positive hand grip is needed. The 4-spoke design distributes hand force evenly across the knob head, allowing controlled tightening and loosening. At 2.5 inches in head diameter and 1.5 inches in overall height, it fits compact control panel layouts and inline valve stems in both light and heavy-duty applications. Maintenance technicians and machinists are the typical installers in manufacturing, HVAC mechanical rooms, and general industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-point spoked design provides firm grip and even torque distribution during manual operation\u003c\/li\u003e\n  \u003cli\u003eCast iron construction offers high strength and resistance to mechanical wear\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides corrosion resistance for light industrial environments\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 threaded stem hole accepts standard 1\/2-13 threaded shafts\u003c\/li\u003e\n  \u003cli\u003eCompact 1.5-inch overall height suits confined panel and valve stem installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket fit for equipment and assemblies using 1\/2-13 threaded control stems, including valve actuators, machine tool controls, and industrial fixtures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools beyond basic hand tools to thread the knob onto the mating stem.
