Key stock is a precision-machined bar stock material used to transmit torque between a shaft and a hub, pulley, sprocket, or gear by seating in a mating keyway. This piece measures 5\/8 inch wide by 5\/16 inch thick and meets ASTM A108 material specification. The zinc finish provides basic corrosion resistance for storage and light-duty service environments. Hardness is rated Rockwell B80-90, giving the stock enough toughness to resist shear under normal drive loads while remaining machinable for field fitting. Machinists, millwrights, and maintenance technicians typically work with this product.\u003c\/p\u003e\n\u003cp\u003eThis key stock is suited for general industrial maintenance and mechanical drive system repair. Common applications include electric motor and pump shaft assemblies, conveyor drive components, and power transmission equipment found in commercial and light industrial facilities. Technicians use it when an OEM-length key is unavailable or when a custom length must be cut and fitted to an existing keyway. The six-piece pack supports shop stock replenishment or multi-shaft jobs requiring consistent material on hand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-carbon steel construction per ASTM A108 for consistent machinability and reliable torque transmission\u003c\/li\u003e\n  \u003cli\u003eRockwell B80-90 hardness balances toughness with ease of cutting, filing, and fitting\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides baseline corrosion protection during storage and installation\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch width by 5\/16 inch height cross-section fits standard square and rectangular keyway configurations\u003c\/li\u003e\n  \u003cli\u003e12-inch length allows field cutting to exact shaft and hub requirements\u003c\/li\u003e\n  \u003cli\u003eSix-piece pack supports shop stock or multi-shaft repair jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement key stock for general power transmission shafts and hubs requiring a 5\/8 inch wide by 5\/16 inch key profile in industrial and commercial mechanical drive applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a millwright or qualified maintenance mechanic. Disconnect and lock out all power to the drive system before removing or installing any shaft keys. Key stock should be cut to length using an appropriate metal saw and deburred before seating to prevent keyway damage. Verify keyway and key dimensions with calipers before final assembly to ensure proper fit and avoid stress concentrations on the shaft.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: ASTM A108\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight (Thickness)\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Rockwell B80-90\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.98 pounds (package)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163208\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 15425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51539439878450,"sku":"15425","price":77.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dbaaae3d5b03d565ba8ec6db438f0c8_a4d1b1b5-4886-43c5-988b-a902761736d3.jpg?v=1785840308","url":"https:\/\/voomisupply.com\/products\/precision-brand-15425-key-stock-5-8-x-5-16-x-12-in-6-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
