Each parallel features four precision-ground faces, giving technicians multiple reference surfaces for consistent, accurate positioning of workpieces on mills, grinders, and surface plates. At 6 inches long, 7\/8 inch high, and 1\/8 inch thick, these are slender, stackable parallels well suited for low-clearance setups. Hardness is rated at 50 Rc, and squareness is held to 0.0005 inches per 1 inch, making them appropriate for close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThese parallels are used in metalworking environments where accurate part elevation and alignment are required. Common applications include vise setup on vertical mills, surface grinding fixture support, and layout work on granite or cast-iron surface plates. They are sold as a matched pair and are appropriate for use by machinists, toolmakers, and precision grinding technicians in both job-shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFour precision-ground faces provide multiple usable reference surfaces per parallel\u003c\/li\u003e\n  \u003cli\u003eHardness of 50 Rc resists wear and deformation during repeated use\u003c\/li\u003e\n  \u003cli\u003eSquareness tolerance of 0.0005 inches per 1 inch for close-tolerance setups\u003c\/li\u003e\n  \u003cli\u003eHigh-grade hardened tool steel construction for long service life\u003c\/li\u003e\n  \u003cli\u003eSlender 1\/8 inch thickness suits low-clearance vise and fixture applications\u003c\/li\u003e\n  \u003cli\u003eSold as a matched pair for balanced workpiece support\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose precision parallel for use with standard machinist vises, surface grinders, and mill setups requiring a 6-inch parallel in 1\/8 inch thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThese parallels are placed by machinists or toolmakers during workpiece setup; no power tools or mechanical fastening is required. Surfaces should be clean and free of chips or burrs before placing parallels to avoid false seating. Handle with care to avoid impact damage that could affect ground surfaces. Inspect periodically for nicks or corrosion that may compromise accuracy.\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: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-grade hardened tool steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallel Type\u003c\/strong\u003e: Four face\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Precision-Ground Sides\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 50 Rc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.0005 inches per 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Matched pair\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 98-454-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722939466034,"sku":"98-454-2","price":48.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eacf9be0091baf9deee08d9b2d9e8942.jpg?v=1788598198","url":"https:\/\/voomisupply.com\/products\/spi-98-454-2-steel-parallel-set-6x7-8x1-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
