Each parallel measures 6 inches in length and 3\/16 inch thick, with height increments of 1\/4 inch across the set. The steel is stress relieved to resist distortion, then precision ground and hardened to 55-62 HRC for consistent dimensional stability. Holes machined through each parallel allow for easier handling and faster fixture setups. The set ships in a fitted wooden case for organized storage and transport.\u003c\/p\u003e\n\u003cp\u003eThis parallel set is suited for use on surface plates, in milling vises, and on magnetic chucks where precise, repeatable workpiece elevation is required. The four pairs span heights from 1 inch to 1-3\/4 inches, covering a range of common setup requirements. Machinists, tool and die makers, and precision metalworking shops will find this set practical for layout inspection, height gauging, and vise setup applications where parallelism tolerances must be held tight.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision ground tool steel holds parallelism to 0.0003 inches and accuracy to 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003eHardness rated at 55-62 HRC for resistance to wear and deformation under load\u003c\/li\u003e\n  \u003cli\u003eStress-relieved material minimizes dimensional drift over time\u003c\/li\u003e\n  \u003cli\u003eThrough-holes in each parallel improve handling and reduce setup time\u003c\/li\u003e\n  \u003cli\u003eSet includes four matched pairs covering 1 inch, 1-1\/4 inch, 1-1\/2 inch, and 1-3\/4 inch heights\u003c\/li\u003e\n  \u003cli\u003eFitted wooden storage case included to protect ground surfaces between uses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-use parallel set suitable for general precision machining and layout applications in shops using milling machines, surface grinders, and inspection equipment requiring parallel workholding support.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eParallels should be cleaned and inspected for burrs before each use to avoid seating errors. When placing parallels in a vise or on a surface plate, ensure mating surfaces are free of chips and coolant residue. Dropping or striking hardened parallels against hard surfaces can cause chipping or cracking; handle with care. Store in the provided wooden case to protect ground surfaces from corrosion and contact damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: 4 Pair\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Height\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Increments\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0010 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\u003eIncludes\u003c\/strong\u003e: Wooden Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePair Dimensions\u003c\/strong\u003e: (1) Pair 3\/16 in x 1 in, (1) Pair 3\/16 in x 1-1\/4 in, (1) Pair 3\/16 in x 1-1\/2 in, (1) Pair 3\/16 in x 1-3\/4 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111800\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: 637-7532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694821540146,"sku":"637-7532","price":245.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/787c060912a68109ddad6bb4db61c684.jpg?v=1788328726","url":"https:\/\/voomisupply.com\/products\/value-collection-637-7532-precision-parallel-set-8-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
