Measuring 6 inches long by 1-3\/4 inches high by 1\/2 inches thick, this parallel delivers a parallelism tolerance of 0.0003 inches, making it well suited for applications where consistent part elevation and accurate workholding are critical. Hardness ranges from 55 to 62 Rc, ensuring the ground faces resist wear over repeated use. Machinists, tool and die makers, and quality technicians rely on parallels like this for vise setup, surface plate layout, and part inspection tasks.\u003c\/p\u003e\n\u003cp\u003eThis parallel is used in manual and CNC machine shop environments for elevating workpieces in vises, supporting parts on surface plates, and establishing reference planes during layout and inspection. It is sold as an individual piece, suitable for use alone or paired with other parallels of matching dimensions. Typical applications include milling machine vise setup, grinding fixture support, and CMM workholding preparation in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallelism of 0.0003 inches for precise, repeatable workpiece elevation\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.001 inches for reliable dimensional reference\u003c\/li\u003e\n  \u003cli\u003eSquareness of 0.0003 inches per 6 inches ensures consistent angular reference\u003c\/li\u003e\n  \u003cli\u003eHardness of 55-62 Rc for long-term wear resistance on ground faces\u003c\/li\u003e\n  \u003cli\u003eTool steel construction withstands demanding shop floor conditions\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/2-inch thickness fits standard milling vise jaw setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose precision parallel for use in standard milling vises, surface plate setups, and toolroom inspection fixtures where 6-inch parallel stock is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eParallels are placed by machinists or toolroom technicians and require no fasteners or permanent installation. Before use, clean all mating surfaces with a lint-free cloth to remove chips, oil, and debris that could affect seating accuracy. Always ensure the machine or vise is de-energized and the spindle is stopped before adjusting workpiece setup. Store parallels on a flat surface or in a dedicated rack to protect ground faces from nicks and corrosion.\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: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/2 inches\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\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: 637-7503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709625008434,"sku":"637-7503","price":96.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71310b86817cae63eca8daf852879564.jpg?v=1788458575","url":"https:\/\/voomisupply.com\/products\/value-collection-637-7503-tool-steel-two-face-parallel","provider":"Voomi Supply","version":"1.0","type":"link"}
