Manufactured from spring steel, this straight edge measures 24 inches in overall length, 1-13\/32 inches wide, and 5\/16 inches thick. The beveled working edge delivers 0.0007 inches of edge flatness and 0.0013 inches of parallelism, making it suitable for applications where close tolerances matter. Machinists, tool and die makers, and metrology technicians reach for tools like this when checking surface flatness, scribing layout lines, or verifying part geometry on surface plates and workbenches.\u003c\/p\u003e\u003cp\u003eThis straight edge is sized for general-purpose precision work in machine shops, fabrication shops, and quality control environments. The 24-inch length covers a practical range of workpiece sizes without being unwieldy on a bench. Spring steel construction resists flex and provides the stiffness needed to hold a true edge under normal shop conditions. It is appropriate for both production inspection routines and one-off layout tasks where a reliable reference edge is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle beveled edge for accurate line scribing and surface checking\u003c\/li\u003e\n\u003cli\u003eEdge flatness of 0.0007 inches for close-tolerance inspection work\u003c\/li\u003e\n\u003cli\u003eParallelism of 0.0013 inches across the working faces\u003c\/li\u003e\n\u003cli\u003eSpring steel construction for stiffness and durability\u003c\/li\u003e\n\u003cli\u003e24-inch length suits a wide range of workpiece and surface plate applications\u003c\/li\u003e\n\u003cli\u003e5\/16-inch thickness provides rigidity without excessive weight\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision straight edge suitable for use on surface plates, machine tables, and flat reference surfaces in machining and inspection applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHandle the beveled edge with care to avoid nicking or burring the reference surface, as even minor damage will compromise measurement accuracy. Store the straight edge flat or suspended to prevent warping over time. Clean the working edge and reference surface before use to remove chips, oils, or debris that could introduce error. No special tools are required for use, but proper storage and handling practices should follow standard metrology shop procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 24 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: 0.0007 inches (15.00 micrometers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0013 inches (33.00 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: 77-632-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51701082620210,"sku":"77-632-8","price":146.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f89e7d2cadf4895d7827d7af84429b86.jpg?v=1788397987","url":"https:\/\/voomisupply.com\/products\/spi-77-632-8-beveled-straight-edge-24-inches-spring-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
