Built with a reamed bore for precise shaft fit, this handle measures 3.25 inches in overall height with a center-to-center distance of 3.125 inches. The hub diameter and hub height each measure 0.6875 inches, and the knob diameter is 1.25 inches. The steel construction provides durability in industrial and light commercial service environments. Licensed trade professionals and maintenance technicians install this type of hardware on machine tools, conveyor systems, and industrial equipment controls.\u003c\/p\u003e\n\u003cp\u003eThis crank handle suits applications where manual rotational input is needed on shafts up to 0.375 inches in diameter. The reamed bore ensures a close-tolerance fit to a round shaft, making it appropriate for machine tool setups, industrial valves, and mechanical assemblies found in manufacturing, HVAC equipment panels, and maintenance environments. The solid steel body handles repeated use in settings where plastic or composite handles would not hold up.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid steel construction for durability in demanding service conditions\u003c\/li\u003e\n  \u003cli\u003eReamed bore at 0.375 inches for close-tolerance shaft engagement\u003c\/li\u003e\n  \u003cli\u003eHub diameter and hub height each at 0.6875 inches for a compact profile\u003c\/li\u003e\n  \u003cli\u003e1.25-inch knob diameter provides comfortable grip during actuation\u003c\/li\u003e\n  \u003cli\u003e3.125-inch center-to-center dimension suits standard manual crank applications\u003c\/li\u003e\n  \u003cli\u003eOverall height of 3.25 inches fits common equipment panel clearances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit crank handle for manual-actuated equipment and machinery using a 0.375-inch reamed bore shaft.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians or millwrights. Power down or de-energize any connected equipment before removing or installing the crank handle.
