It measures 72 inches in length, 3-5\/32 inches in width, and 9\/32 inches in thickness, with a certified edge flatness of 0.0004 inches and parallelism of 0.0024 inches. The beveled edge provides a precise reference line for scribing, checking surface flatness, or verifying straightness across long workpieces. Machinists, toolmakers, pipefitters, and fabricators rely on this tool when accurate alignment or layout is required over extended spans. Its steel construction offers the rigidity and dimensional stability needed for demanding shop and field conditions.\u003c\/p\u003e\n\u003cp\u003eThis straight edge is suited for use in machine shops, fabrication facilities, and precision layout applications where a long, reliable reference surface is required. It is commonly used to check flatness on large machine beds, verify alignment of structural members, and perform scribing operations on plate stock. The 72-inch length makes it appropriate for applications that shorter rules or shorter straight edges cannot effectively span.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEdge flatness of 0.0004 inches for precision layout and inspection work\u003c\/li\u003e\n  \u003cli\u003eParallelism of 0.0024 inches across the full length\u003c\/li\u003e\n  \u003cli\u003eSingle beveled edge for accurate scribing and alignment reference\u003c\/li\u003e\n  \u003cli\u003e72-inch length spans large workpieces and machine surfaces\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and long-term dimensional stability\u003c\/li\u003e\n  \u003cli\u003e9\/32-inch thickness provides resistance to flex during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose precision straight edge for use in machine shop, fabrication, and industrial layout applications requiring a 72-inch reference tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHandle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils on the precision ground surface. Store horizontally or vertically in a protected location to prevent warping or edge damage. Inspect the reference edge for nicks or burrs before each use, as contact damage can affect accuracy. Cleaning and light oiling after use will extend the service life of the steel surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 72 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3-5\/32 inches (80.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 9\/32 inches (7.14 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEdge Flatness\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0024 inches\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.625 pounds\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51461\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539118850354,"sku":"51461","price":1076.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/749b930ddebe8a3803be82b783964788.jpg?v=1785834938","url":"https:\/\/voomisupply.com\/products\/starrett-51461-beveled-straight-edge-72-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
