Each parallel is 6 inches long and 1\/8 inch thick, covering a height range of 1\/2 inch to 1-5\/8 inch in 1\/8-inch increments. The set is manufactured from alloy steel hardened to 50-54 RC, delivering the durability and rigidity required for accurate milling, grinding, and inspection work. Parallelism tolerance is held to 0.0008 inches and overall accuracy is 0.0010 inches, making this set suitable for close-tolerance setups where consistent part seating is critical. The ten matched pairs are stored in a fitted plastic case for organized storage and protection between uses.\u003c\/p\u003e\n\u003cp\u003eThis parallel set is used by machinists and toolroom professionals in manual and CNC milling operations, surface grinding setups, and layout or inspection tasks. The thin 1\/8-inch profile allows it to fit in vises and fixtures where standard-width parallels would be obstructed. The incremental height range covers a broad span of common workpiece elevations, reducing the need to swap between multiple sets during a job. Typical users include production machinists, tool and die makers, and apprentices building out a precision workholding kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-piece set organized as 10 matched pairs for consistent, repeatable workholding\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction hardened to 50-54 RC for wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eThin 1\/8-inch profile fits tight vise and fixture clearances where wider parallels cannot\u003c\/li\u003e\n  \u003cli\u003eHeight range of 1\/2 inch to 1-5\/8 inch in 1\/8-inch increments covers common workpiece elevations\u003c\/li\u003e\n  \u003cli\u003eParallelism held to 0.0008 inches with 0.0010-inch overall accuracy\u003c\/li\u003e\n  \u003cli\u003eIncludes fitted plastic case for organized storage and protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose thin parallel set compatible with standard milling vises, surface grinders, and inspection fixtures that accept 1\/8-inch-thick parallels in the 1\/2-inch to 1-5\/8-inch height range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists during machine setup without the need for special tools. Clean mating surfaces of the vise and workpiece before placing parallels to prevent debris from affecting seating accuracy. Never use parallels as a striking surface or pry tool, as this can compromise hardness and flatness. Store the set in the provided plastic case when not in use to protect ground surfaces from 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: 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 (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Height\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Height\u003c\/strong\u003e: 1-5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Increments\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0008 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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 50-54 RC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Plastic case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.26 pounds\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: 637-7030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721484206386,"sku":"637-7030","price":141.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d880bc1d0070c6c0bab394fe6caa1f7.jpg?v=1788577960","url":"https:\/\/voomisupply.com\/products\/value-collection-637-7030-thin-parallel-set-20-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
