Constructed from spring steel, it measures 12 inches in overall length, 1-13\/32 inches wide, and 5\/16 inches thick. The beveled edge delivers a flatness tolerance of 0.0005 inches (12 micrometers) and a parallelism tolerance of 0.0009 inches (24 micrometers), making it a reliable reference tool for close-tolerance work. Machinists, tool and die makers, and quality control technicians rely on straight edges like this for scribing, checking flatness, and transferring layout lines accurately across a workpiece.\u003c\/p\u003e\u003cp\u003eThis straight edge is suited for general precision layout and inspection tasks in job shops, production machining environments, and toolrooms. The spring steel construction provides durability and resistance to deformation under typical shop conditions. Its compact 12-inch length makes it practical for benchtop use and for verifying surfaces on medium-sized workpieces or machine components. It ships individually and is sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle beveled edge for accurate scribing and surface reference work\u003c\/li\u003e\n\u003cli\u003eEdge flatness of 0.0005 inches (12 micrometers) for close-tolerance inspection\u003c\/li\u003e\n\u003cli\u003eParallelism of 0.0009 inches (24 micrometers) across the length\u003c\/li\u003e\n\u003cli\u003eSpring steel construction for rigidity and long service life\u003c\/li\u003e\n\u003cli\u003e12-inch overall length suitable for benchtop and medium-scale layout tasks\u003c\/li\u003e\n\u003cli\u003eCompact profile at 1-13\/32 inches wide and 5\/16 inches thick for easy handling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision straight edge compatible with standard layout and inspection workflows in machine shops, toolrooms, and fabrication facilities where close-tolerance surface verification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eStraight edges are hand tools requiring no installation. Handle with clean, dry hands or cotton gloves to prevent corrosion from skin oils on the spring steel surface. Store flat or in a protective case to maintain edge flatness over time. Do not use as a cutting guide with rotary tools, as edge contact with cutting forces can compromise the reference surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-13\/32 inches (35.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 5\/16 inches (7.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Flatness\u003c\/strong\u003e: 0.0005 inches (12 micrometers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0009 inches (24 micrometers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Beveled Edges\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 77-630-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689669230898,"sku":"77-630-2","price":76.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b3893c1fc0fdda99eba16abac7dcfa2.jpg?v=1788262700","url":"https:\/\/voomisupply.com\/products\/spi-77-630-2-beveled-straight-edge-12-inches-spring-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
