Cut from cold drawn steel with a plain finish, this key stock measures 7\/16 inches high by 7\/16 inches wide by 12 inches long. The undersized designation means the cross-section is machined slightly below nominal, allowing a controlled slip fit into standard keyways during assembly. Machinists, millwrights, and maintenance technicians working on industrial drive trains, pumps, and conveyor systems rely on key stock of this profile for accurate power transmission and repeatable positioning.\u003c\/p\u003e\u003cp\u003eThis key stock is suited for light to medium-duty mechanical assemblies in both industrial and commercial maintenance settings. It is commonly cut to length on-site using a hacksaw, cold saw, or mill and fitted into standard 7\/16-inch keyways on shafts and hubs. Typical applications include pump and motor coupling assemblies, fan shaft retention, and general-purpose machine repair where a replaceable key is required. The 12-inch bar length provides enough stock for multiple short keys from a single piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUndersized cross-section for a controlled slip fit in standard 7\/16-inch keyways\u003c\/li\u003e\n\u003cli\u003eCold drawn steel construction provides consistent dimensional tolerances and good surface hardness\u003c\/li\u003e\n\u003cli\u003ePlain finish — no coating to interfere with close-tolerance fits\u003c\/li\u003e\n\u003cli\u003e12-inch bar length yields multiple cut-to-length keys per piece\u003c\/li\u003e\n\u003cli\u003eSquare 7\/16 inches x 7\/16 inches profile suits common shaft and hub keyway combinations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard undersized key stock replacement for mechanical drive assemblies using 7\/16-inch square keyways on shafts and hubs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or millwright. De-energize and lock out the drive system before removing or fitting any shaft keys. Key stock should be cut to length with a cold saw or mill; avoid grinding cuts that can harden the ends and complicate fitting. Verify keyway dimensions and shaft tolerances before installation to ensure proper seating and engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Stock Type\u003c\/strong\u003e: Undersized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cold Drawn Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163208\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 33965\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694430814514,"sku":"33965","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7a6deb3465bddbac930d81affdefa52.jpg?v=1788324424","url":"https:\/\/voomisupply.com\/products\/value-collection-33965-undersized-key-stock-7-16x7-16x12-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
