Each parallel measures 9 inches long, 1-1\/2 inches high, and 3\/4 inches thick. The pair holds a parallelism tolerance of 0.0002 inches, making it suitable for precision setups where consistent height reference is critical. Hardened to 58 Rc, the steel resists wear and maintains dimensional stability through repeated use in machine shop environments. Machinists, toolmakers, and setup techs rely on parallels like these to establish flat, repeatable datum surfaces before clamping or indicating a part.\u003c\/p\u003e\n\u003cp\u003eThese parallels are suited for general-purpose and precision machining applications in job shops, toolrooms, and manufacturing cells. They function as workholding support under vise jaws, on surface plates for inspection setups, or on magnetic chucks for grinding operations. The matched-pair format ensures both pieces share the same verified height, which is essential when supporting a single workpiece across two contact points. Sold as a set of two, they are a standard addition to any machinist setup kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallelism tolerance of 0.0002 inches for precision workholding and inspection setups\u003c\/li\u003e\n  \u003cli\u003eHardened to 58 Rc for wear resistance and long-term dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTool steel construction provides strength and resistance to deformation under clamping load\u003c\/li\u003e\n  \u003cli\u003eSold as a matched pair with verified equal height between both pieces\u003c\/li\u003e\n  \u003cli\u003eCompact 3\/4 inch thickness fits standard vise jaw clearances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard matched-pair tool steel parallel suitable for use with milling vises, surface plates, magnetic chucks, and similar workholding setups in general machining and toolroom applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eParallels are placed by machinists and toolmakers during workpiece setup — no permanent installation is required. Clean contact surfaces on both the parallel and the vise jaw or chuck before placing to prevent false seating from chips or debris. Verify seating by lightly tapping the workpiece and listening for a solid tone with no rocking. Store parallels as a matched pair to preserve the verified tolerance relationship between the two pieces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0002 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: 58 Rc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.03 pounds\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: 637-7624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715313172786,"sku":"637-7624","price":120.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ce1ea734a6caefb9a9bbbff372cf2f1.jpg?v=1788511911","url":"https:\/\/voomisupply.com\/products\/value-collection-637-7624-tool-steel-parallel-9x1-5x0-75in-pair","provider":"Voomi Supply","version":"1.0","type":"link"}
