Each piece measures 5\/16 inch wide by 3\/16 inch high by 12 inches long and meets ASTM A108 material specification. Hardness is rated Rockwell B80-90, providing reliable shear resistance under normal drive loads. This package contains six pieces of identical key stock, giving technicians extra material for multiple repairs or installations in a single job. Licensed millwrights, maintenance mechanics, and industrial service technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis key stock is suited for general-purpose power transmission applications in both light industrial and commercial mechanical systems. It fits standard keyway slots machined to 5\/16 x 3\/16 inch dimensions and is commonly used during motor, pump, fan, and conveyor shaft service. The zinc finish provides basic corrosion resistance for indoor and moderate-environment installations. The 12-inch length allows field cutting to exact fit using a hacksaw or cold chisel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-carbon steel construction meeting ASTM A108 material specification\u003c\/li\u003e\n  \u003cli\u003eRockwell B80-90 hardness rating for reliable drive-load resistance\u003c\/li\u003e\n  \u003cli\u003eZinc finish for basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch width by 3\/16 inch height cross-section for standard keyway fitment\u003c\/li\u003e\n  \u003cli\u003e12-inch length allows field trimming to required size\u003c\/li\u003e\n  \u003cli\u003eSix pieces per package for multi-use or backup stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/16 x 3\/16 inch keyway slots on shafts and hubs in general-purpose mechanical power transmission assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed millwright or qualified maintenance mechanic. De-energize and lock out all power to the drive system before removing or installing key stock. The key stock may be cut to length using a hacksaw and deburred before fitting into the keyway. Ensure the keyway slot dimensions match the key stock cross-section to prevent slippage or shaft damage.\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: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\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: 1.19 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: 15225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51542806888754,"sku":"15225","price":33.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dbaaae3d5b03d565ba8ec6db438f0c8_c793ae20-c2c3-4a2b-b13e-29169e319142.jpg?v=1785907993","url":"https:\/\/voomisupply.com\/products\/precision-brand-15225-key-stock-5-16x3-16x12-in-6pc","provider":"Voomi Supply","version":"1.0","type":"link"}
