A double square functions as both a try square and a miter square, allowing the user to verify 90-degree and 45-degree angles from a single tool. The blade is 5\/32 inch wide and seats into a hardened steel head that locks at the centerline of the stock. Layout techs, pipefitters, millwrights, and precision machinists rely on this tool for transferring measurements, scribing lines, and checking squareness on finished surfaces.\u003c\/p\u003e\n\u003cp\u003eThe 50117 suits precision layout and inspection work in machine shops, fabrication facilities, and light construction environments. Its compact 2.5-inch blade makes it practical for close-tolerance work in confined areas where a larger combination square would be unwieldy. The English graduation system covers standard fractional increments, making the tool directly readable against inch-based drawings and tolerances without conversion.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5-inch blade length for compact, close-tolerance layout work\u003c\/li\u003e\n  \u003cli\u003eDual English graduations: 1\/32 inch and 1\/64 inch for fine measurement resolution\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch blade width provides a stable scribing edge\u003c\/li\u003e\n  \u003cli\u003eSteel blade and head construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003eChecks both 90-degree and 45-degree angles from a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose precision layout square suitable for use in machine shop, fabrication, and trade inspection applications requiring English-graduated measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand tool. Before use, verify the blade locks securely in the head with no lateral play, as a loose blade will produce inaccurate readings. Clean mating surfaces of the workpiece before seating the head to prevent debris from introducing squareness error. Store the square in a protective case or pouch to prevent blade nicks that would compromise measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 5\/32 inch (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: English\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduations\u003c\/strong\u003e: 1\/32 inch and 1\/64 inch\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: 0.125 pounds\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: 50117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539498762546,"sku":"50117","price":173.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10f08e7826d27a63e87dbba1e12a1eb7.jpg?v=1785841833","url":"https:\/\/voomisupply.com\/products\/starrett-50117-double-square-2-5-inch-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
