Key stock is used to transmit torque between a shaft and a hub, such as a pulley, sprocket, gear, or coupling. This piece measures 1\/8 inch wide by 1\/8 inch tall by 12 inches long with a plain finish. Hardness is rated at Rockwell B80-90, providing reliable shear strength for light-duty power transmission applications. Each package contains 6 pieces. Machinists, millwrights, and maintenance technicians typically cut and fit this stock to length on the job.\u003c\/p\u003e\n\u003cp\u003eMill stock key stock is used across a wide range of industrial, commercial, and facility maintenance applications. It is suited for keyed shaft assemblies found in pumps, fans, conveyor drives, and general machinery. The 1\/8 by 1\/8 inch cross section fits standard keyways of the same dimension. The 12-inch length allows the installer to cut pieces to the required length using a bandsaw, angle grinder, or cut-off wheel. This product ships in a 6-piece pack, making it practical for shops and service vehicles that stock common key stock sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-carbon steel construction per ASTM A108 material specification\u003c\/li\u003e\n  \u003cli\u003eRockwell B80-90 hardness for consistent shear performance in keyed joints\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch x 1\/8 inch cross section fits standard keyways of the same size\u003c\/li\u003e\n  \u003cli\u003e12-inch length can be cut to fit during installation\u003c\/li\u003e\n  \u003cli\u003ePlain finish for direct use or further machining\u003c\/li\u003e\n  \u003cli\u003ePackaged as 6 pieces per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard mill stock key stock replacement for any keyed shaft and hub assembly requiring a 1\/8 inch x 1\/8 inch keyway cross section.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or millwright.
