Each piece is 12 inches long and measures 4 mm x 4 mm in cross-section, conforming to DIN 6880 material specifications. Manufactured from low-carbon steel with a gold dichromate finish, this key stock resists corrosion while maintaining the ductility needed for standard keyed shaft applications. Machinists, millwrights, and maintenance technicians use this stock to cut custom-length keys on the job or in the shop.\u003c\/p\u003e\n\u003cp\u003eThis key stock is suited for general industrial and mechanical maintenance applications where a 4 mm square profile is required. Common uses include fitting keys in motor shafts, conveyor drive components, pump couplings, and similar rotating power-transmission assemblies. The 12-inch length provides flexibility for cutting multiple keys from a single piece. The gold dichromate finish offers a degree of corrosion resistance for storage and moderate service environments. Each pack contains 6 pieces, making it practical for shops that service multiple machines at once.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare profile at 4 mm x 4 mm cross-section per DIN 6880 specification\u003c\/li\u003e\n  \u003cli\u003e12-inch length per piece allows on-site cutting to required key length\u003c\/li\u003e\n  \u003cli\u003eLow-carbon steel construction provides ductility suitable for standard keyed connections\u003c\/li\u003e\n  \u003cli\u003eGold dichromate finish adds corrosion resistance for storage and general service\u003c\/li\u003e\n  \u003cli\u003ePack of 6 pieces supports multi-machine maintenance tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose key stock for rotating power-transmission assemblies requiring a 4 mm square keyway profile per DIN 6880.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or millwrights using a bandsaw, hacksaw, or cold saw to cut the stock to the required length. De-burr all cut edges before fitting to prevent shaft or hub damage. Ensure the shaft and equipment are fully de-energized and locked out before removing or installing any keys. Verify keyway dimensions with calipers before installation to confirm proper fit and avoid interference.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Stock Type\u003c\/strong\u003e: Square Key Stock\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: DIN 6880\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Gold Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Height\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Width\u003c\/strong\u003e: 4 mm\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: 0.51 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Not Rated\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: 04010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51542512042290,"sku":"04010","price":29.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3b8af59e51f82733ffa08878009e2f3_07c0663e-08d9-4033-9bbf-82033ce7c2bf.jpg?v=1785902431","url":"https:\/\/voomisupply.com\/products\/precision-brand-04010-square-key-stock-12-in-6-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
