Key stock is a precision-cut bar used to mechanically lock rotating components — such as gears, pulleys, and sprockets — to shafts in power transmission assemblies. Machined from open hearth steel, this key stock provides the shear strength and dimensional consistency required for reliable shaft-to-hub engagement. It is a standard component stocked and installed by millwrights, maintenance mechanics, and industrial service technicians across commercial and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis key stock is suited for use in general power transmission systems where a 0.375-inch key width is specified. Common install scenarios include pump shafts, fan assemblies, conveyor drives, and motor couplings. It is sold individually and cut to a 12-inch length, allowing the technician to trim the key to the required finished length on site using standard metalworking tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOpen hearth steel construction provides consistent hardness and shear resistance\u003c\/li\u003e\n  \u003cli\u003e0.375-inch width by 12-inch length suits a wide range of standard keyway dimensions\u003c\/li\u003e\n  \u003cli\u003e12-inch length allows field trimming to application-specific finished length\u003c\/li\u003e\n  \u003cli\u003eSold as a single piece for targeted replacement or repair use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or new-installation key stock for shaft-and-hub assemblies requiring a 0.375-inch key width in industrial and commercial power transmission systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified millwright or maintenance mechanic. De-energize and lock out the drive system before removing or installing any shaft components. Key stock should be cut to length and deburred before fitting into the keyway. Ensure proper fit within the keyway tolerances — a loose fit can cause fretting and premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Open hearth steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.484 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613180192\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: NATIONAL MARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N180190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51344710336818,"sku":"N180190","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550220.jpg?v=1782041187","url":"https:\/\/voomisupply.com\/products\/national-marker-n180190-steel-key-stock-0-375x12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
