Each piece measures 0.75 inches wide by 0.5 inches tall by 12 inches long and meets ASTM A108 material specification. Hardness is rated at Rockwell B80-90, providing the strength needed for standard power transmission applications without being overly brittle. This package contains six pieces, making it suitable for stocking a shop or completing multiple repairs in a single order. Machinists, millwrights, and maintenance mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis key stock is used in industrial, commercial, and light manufacturing settings wherever keyed shaft connections are required. Typical applications include motor-to-pump couplings, conveyor drive assemblies, fan shaft connections, and gearbox installations. The 12-inch length allows the stock to be cut to the required keyway length on-site using standard cutting tools. The zinc finish provides a measure of corrosion resistance for use in moderately humid environments such as mechanical rooms, pump stations, and plant floors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-carbon steel construction meets ASTM A108 specification for consistent mechanical properties\u003c\/li\u003e\n  \u003cli\u003eRockwell B80-90 hardness suitable for standard power transmission shaft connections\u003c\/li\u003e\n  \u003cli\u003eZinc finish adds corrosion resistance for use in damp or humid service environments\u003c\/li\u003e\n  \u003cli\u003e12-inch length can be cut to fit a wide range of keyway depths and shaft sizes\u003c\/li\u003e\n  \u003cli\u003ePackage of 6 pieces supports shop stocking and multi-unit repair jobs\u003c\/li\u003e\n  \u003cli\u003e0.75 inch width by 0.5 inch height profile fits correspondingly sized keyways\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard key stock replacement for keyed shaft assemblies requiring a 0.75 inch wide by 0.5 inch tall profile in accordance with ANSI and ASTM A108 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or millwright. Shut down and lock out the drive system before removing or installing any shaft hardware, following OSHA lockout-tagout procedures. Cut the key stock to the correct length using a bandsaw, cold saw, or angle grinder, and deburr all cut edges before fitting. Do not force the key into the keyway with a hammer strike that could damage the shaft or keyway walls.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight (Thickness)\u003c\/strong\u003e: 0.5 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\u003ePackage Weight\u003c\/strong\u003e: 7.65 pounds\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: 15550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51543437148466,"sku":"15550","price":177.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dbaaae3d5b03d565ba8ec6db438f0c8_430f462a-f0bb-4f06-ae5a-4e011deb1203.jpg?v=1785918601","url":"https:\/\/voomisupply.com\/products\/precision-brand-15550-key-stock-0-75x0-5x12-in-zinc-6pc","provider":"Voomi Supply","version":"1.0","type":"link"}
