At 24 inches in length, it delivers a verified edge flatness of 0.0004 inches and parallelism of 0.0008 inches, making it suitable for applications where a reliable, repeatable reference surface is required. The beveled edge reduces contact area to a defined line, improving accuracy when scribing or checking for gaps. Machinists, toolmakers, and precision measurement technicians are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThe 51457 is suited for use on machine tables, surface plates, and fabrication benches in job shops, maintenance departments, and manufacturing environments. Its 24-inch length covers a practical range for checking larger workpieces, sheet stock, or machine ways. The single beveled edge makes it straightforward to position and index against a workpiece without ambiguity about which edge is the reference surface. The steel construction provides durability for repeated shop use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEdge flatness of 0.0004 inches for reliable precision reference work\u003c\/li\u003e\n\u003cli\u003eParallelism held to 0.0008 inches across the full length\u003c\/li\u003e\n\u003cli\u003eSingle beveled edge reduces contact to a defined line for scribing and gap checking\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n\u003cli\u003e24-inch overall length suits larger workpieces and machine surface checks\u003c\/li\u003e\n\u003cli\u003eCompact profile at 1-13\/32 inches wide and 11\/64 inches thick for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision straight edge for use on surface plates, machine tables, and fabrication setups where a beveled steel reference tool is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this tool. Handle with clean, dry hands or lint-free gloves to avoid corrosion on the precision ground surfaces. Store flat or in a protective case to prevent warping or edge damage. Periodically verify the edge flatness against a calibrated surface plate per your shop calibration schedule.\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: 11\/64 inches (4.37 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: 0.0008 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\u003eEdge Type\u003c\/strong\u003e: Beveled\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: 1.813 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 51457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542881141042,"sku":"51457","price":250.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33040d0df99dd25f4d36e0b9cb3a5721.jpg?v=1785909797","url":"https:\/\/voomisupply.com\/products\/starrett-51457-beveled-straight-edge-24-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
