Cut from low-carbon steel with a plain mill finish, it measures 0.75 inches high by 0.75 inches wide by 12 inches long and is sold as a single piece. Machinists, millwrights, and maintenance technicians use this stock when fabricating or replacing keys in pulleys, gears, sprockets, and couplings. The square cross-section profile suits standard keyway configurations that call for 3\/4-inch key stock.\u003c\/p\u003e\u003cp\u003eThis key stock is appropriate for general industrial and commercial maintenance applications where a standard square mill key profile is required. It can be cut to a custom length on a bandsaw or milling machine to fit a specific shaft and hub assembly. Typical uses include OEM fabrication, field repair of rotating equipment, and preventive maintenance on conveyor drives, pump shafts, and fan assemblies. It is stocked as a 12-inch bar to allow multiple keys to be produced from a single piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSquare 0.75-inch by 0.75-inch cross section fits standard 3\/4-inch keyway slots\u003c\/li\u003e\n\u003cli\u003eLow-carbon steel construction provides adequate shear strength for general power-transmission service\u003c\/li\u003e\n\u003cli\u003ePlain mill finish allows for easy marking, cutting, and fitting without surface treatment removal\u003c\/li\u003e\n\u003cli\u003e12-inch length yields multiple finished keys per bar, reducing material waste\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging suits jobsite and shop use without excess inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension mill key stock for use in any 3\/4-inch square keyway application across general industrial, commercial, and maintenance power-transmission assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or millwright. De-energize and lock out the machine before removing or installing any key. Cut the key stock to the required length using a bandsaw, cold saw, or milling machine, then deburr all edges before fitting. Verify keyway and key dimensions with calipers before final assembly to ensure proper fit and torque transmission.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Stock Type\u003c\/strong\u003e: Mill\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Low-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: Low Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163208\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION BRAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51539286360370,"sku":"56509","price":31.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d21571eb4944ce80e1d634662cedb24.jpg?v=1785837818","url":"https:\/\/voomisupply.com\/products\/precision-brand-56509-mill-key-stock-3-4-x-3-4-x-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
