Each parallel measures 6 inches long, 1-1\/4 inches high, and 1\/2 inch thick, with a parallelism tolerance of 0.0003 inches across the full length. Hardness is rated at 55-62 Rc, providing the durability and resistance to wear that production and toolroom environments demand. These parallels are used to support and position workpieces accurately in vises, fixtures, and on surface plates during milling, grinding, and inspection operations.\u003c\/p\u003e\n\u003cp\u003eThis matched pair is suited to machine shops, tool and die operations, and general metalworking setups where consistent, repeatable workpiece elevation is required. The 6-inch length and 1-1\/4-inch height make them practical for a wide range of vise sizes commonly found in vertical milling and surface grinding applications. Squareness is held to 0.0003 inches per 6 inches, supporting use in close-tolerance layout and inspection work as well as standard fixturing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallelism tolerance of 0.0003 inches for high-precision workpiece positioning\u003c\/li\u003e\n  \u003cli\u003eSquareness of 0.0003 inches per 6 inches\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated to 0.001 inches\u003c\/li\u003e\n  \u003cli\u003eTool steel construction hardened to 55-62 Rc for long service life\u003c\/li\u003e\n  \u003cli\u003eSold as a matched pair for consistent setup repeatability\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/2-inch thickness fits standard vise configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style replacement or direct-use matched parallel set suitable for standard machinist vises, surface plates, and fixturing applications in milling and grinding operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eParallels are typically positioned by machinists or toolmakers inside a milling or grinding vise beneath the workpiece before clamping. Clean all mating surfaces before placement to prevent measurement error caused by chips or debris. Handle with care to avoid nicks or burrs on the precision ground faces, as surface damage will affect accuracy. Store in a protective case or wrapped when not in use to maintain the ground surfaces.\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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\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\u003eHardness\u003c\/strong\u003e: 55-62 Rc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Matched Pair\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: 637-7501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701547434290,"sku":"637-7501","price":90.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6cdc81a3a84bb35deeb1618fa2d5a2b.jpg?v=1788401134","url":"https:\/\/voomisupply.com\/products\/value-collection-637-7501-tool-steel-two-face-parallel","provider":"Voomi Supply","version":"1.0","type":"link"}
