Cut from open hearth steel, this key stock provides reliable shear strength and dimensional consistency for both original installation and maintenance repair work. At 0.25 inches wide by 12 inches long, it fits standard keyway slots commonly found in motors, pumps, and power transmission assemblies. Machinists, millwrights, and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis key stock is suited for general industrial and mechanical maintenance applications where a standard square or rectangular key is required to transmit torque between a shaft and a hub. The 12-inch length allows the piece to be cut to a custom fit on-site using a hacksaw or angle grinder. It is sold individually, making it a practical single-piece replacement option for a worn or missing key in light to medium duty drive assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOpen hearth steel construction provides consistent hardness and machinability\u003c\/li\u003e\n\u003cli\u003e0.25 inches x 12 inches dimensions suit standard keyway slots\u003c\/li\u003e\n\u003cli\u003eFull 12-inch length can be cut to custom fit on-site\u003c\/li\u003e\n\u003cli\u003eSold individually for single-piece repair or replacement\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.221 pounds for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement key stock for mechanical drive assemblies requiring a 0.25-inch wide keyway slot on motors, pumps, gearboxes, or similar rotating equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or maintenance mechanic.
