Measuring 6 inches long by 1-1\/4 inches high by 3\/16 inches thick, it is ground from tool steel hardened to 55-62 HRC for long-term wear resistance. Parallelism is held to 0.0003 inches, making it suitable for precision setups where consistent, repeatable part positioning is critical. Machinists, toolmakers, and setup technicians are the primary users of this type of tooling component.\u003c\/p\u003e\n\u003cp\u003eThis parallel is well suited to manual machine shops, CNC setup environments, and quality-inspection stations. Its 3\/16-inch thickness makes it appropriate for applications where a slimmer profile is needed inside a vise or under a workpiece. The two-face ground design ensures both faces are usable reference surfaces, doubling effective utility. It is sold individually, making it practical for replacing a single worn or damaged parallel from an existing set without purchasing a full set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallelism of 0.0003 inches for repeatable precision setups\u003c\/li\u003e\n  \u003cli\u003eAccuracy to 0.001 inches across the working surfaces\u003c\/li\u003e\n  \u003cli\u003eSquareness held to 0.0003 inches per 6 inches\u003c\/li\u003e\n  \u003cli\u003eTool steel construction hardened to 55-62 HRC for wear resistance\u003c\/li\u003e\n  \u003cli\u003eTwo-face ground design — both faces serve as usable reference surfaces\u003c\/li\u003e\n  \u003cli\u003eCompact 3\/16-inch thickness for use in tight vise and fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-profile precision parallel suitable for use with most manual and CNC milling vises, surface plates, and toolroom fixture setups requiring a 6-inch length and 3\/16-inch thickness profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePrecision parallels are installed and removed by hand or with the aid of a soft mallet — never strike with a steel hammer, as this can damage ground surfaces. Clean the vise and workpiece contact surfaces before placing the parallel to prevent chips or grit from introducing positioning error. Parallels should be stored flat and protected from contact with other hardened tooling to preserve ground surface integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallel Type\u003c\/strong\u003e: Two Face\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.0003 inches per 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 55-62 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 637-7505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710256283954,"sku":"637-7505","price":73.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba814f4b7f8b6d97104ad02b7ace61d1.jpg?v=1788464858","url":"https:\/\/voomisupply.com\/products\/value-collection-637-7505-two-face-parallel-tool-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
