Each parallel measures 6 inches in length and 1\/8 inch in thickness, with a maximum height of 1-5\/8 inches. The set is hardened to 52-58 HRC for long-term wear resistance and dimensional stability. Parallelism and accuracy are held to 0.0002 inches, making these parallels suitable for tight-tolerance work on mills, surface grinders, and inspection fixtures. Machinists and toolroom technicians are the primary users of this type of precision ground tooling.\u003c\/p\u003e\u003cp\u003eThis parallel set is used in machine shop environments for supporting and leveling workpieces in vises, on surface plates, and under clamps during milling and grinding operations. The thin 1\/8-inch profile allows use in setups where standard-width parallels cannot fit. The set ships as 10 matched pairs, ensuring consistent height pairing across each parallel pair for repeatable setup work. The 20-piece count provides coverage across a range of setup heights within the 1-5\/8 inch maximum range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20 pieces sold as 10 matched pairs for consistent setup heights\u003c\/li\u003e\n\u003cli\u003eThin 1\/8-inch thickness for tight-clearance workholding applications\u003c\/li\u003e\n\u003cli\u003e6-inch length accommodates standard milling vise and fixture setups\u003c\/li\u003e\n\u003cli\u003e52-58 HRC hardness for wear resistance and long service life\u003c\/li\u003e\n\u003cli\u003eParallelism and accuracy held to 0.0002 inches for precision work\u003c\/li\u003e\n\u003cli\u003eMaximum height of 1-5\/8 inches with 1\/8-inch height increments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose thin parallel set for use in machine shop vises, surface grinders, and inspection fixtures requiring a 1\/8-inch thick profile parallel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eParallels should be cleaned and inspected for burrs or debris before each use to maintain accuracy. Handle with care to avoid dropping, which can alter ground surfaces and compromise parallelism. No power source or code compliance is required for parallel sets, but proper storage in a case or protective holder is recommended to prevent damage to precision ground surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: 10 matched pairs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Height\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight Increments\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 52-58 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.22 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1\/8\" SPI 10 PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689034809650,"sku":"1\/8\" SPI 10 PR","price":220.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b984e95f66cfdbaf60b425fcffb65e7.jpg?v=1788254104","url":"https:\/\/voomisupply.com\/products\/spi-1-8-spi-10-pr-thin-parallel-set-20-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
