It features a 6-inch blade length and a 4-5\/16-inch base length, with beveled edges on both sides for accurate scribing with marking tools. The square is machined to an accuracy of 0.0002 inches, making it suitable for close-tolerance layout work. Constructed from steel, it is built to withstand regular shop use. Machinists, toolmakers, and fabricators rely on this type of square for verifying 90-degree relationships and transferring reference lines on workpieces.\u003c\/p\u003e\u003cp\u003eThis square is suited for bench-top layout work in machine shops, fabrication shops, and maintenance environments. It is used alongside scribers, height gauges, and surface plates when marking out stock or checking squareness on machined parts. The beveled edges on both sides allow the square to seat cleanly against a reference surface while a scriber traces the blade edge. It is appropriate for both production and one-off toolroom applications where consistent angular reference is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBlade length of 6 inches for versatile layout reach\u003c\/li\u003e\n\u003cli\u003eBase length of 4-5\/16 inches provides a stable reference footing\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.0002 inches for close-tolerance inspection and scribing\u003c\/li\u003e\n\u003cli\u003eBeveled on both edges for clean contact with marking tools\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n\u003cli\u003eCompatible with standard marking tools for layout work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with marking tools in general layout and inspection applications.

Keep the reference surfaces clean and free of burrs before use to maintain accuracy. Store the square protected from impact and corrosion to preserve its calibrated edges. Periodic verification against a known reference surface is recommended to confirm ongoing accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 4-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBevel Edge\u003c\/strong\u003e: Yes, beveled on both edges\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: 0.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With\u003c\/strong\u003e: Marking tools\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: 50283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543116644658,"sku":"50283","price":515.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b8f2cbcf1ca9da7db6a04da278f834c.jpg?v=1785915845","url":"https:\/\/voomisupply.com\/products\/starrett-50283-steel-square-6-in-blade-4-5-16-in-base","provider":"Voomi Supply","version":"1.0","type":"link"}
