The set includes three beveled squares and a triangular straight edge, all constructed from hardened and ground steel for long-term dimensional accuracy. Base lengths in the set measure 3\/4 inches, 1-1\/8 inches, and 1-15\/16 inches. Corresponding blade lengths are 1 inch, 1-1\/2 inches, 1-9\/16 inches, and 2-15\/16 inches. The hardened and ground finish on all straight-edge sides ensures consistent reference surfaces for scribing and squaring work across a range of part sizes.\u003c\/p\u003e\u003cp\u003eThis square set is suited for machinists, tool-and-die workers, pipefitters, and precision fabricators who require reliable small-scale reference tools at the bench or in the field. The range of base and blade lengths makes the set versatile for checking squareness on small components, layout work on flat stock, and verifying angles during fitting and assembly operations. The included case keeps all four pieces organized and protected during storage and transport.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHardened and ground steel construction for accurate, repeatable reference surfaces\u003c\/li\u003e\n\u003cli\u003eStraight-edge sides on all pieces for clean scribing and squaring\u003c\/li\u003e\n\u003cli\u003eIncludes 3 beveled squares covering multiple base and blade length combinations\u003c\/li\u003e\n\u003cli\u003eTriangular straight edge included as a fourth layout reference tool\u003c\/li\u003e\n\u003cli\u003eProtective case included for organized storage of all 4 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision layout and inspection square set suitable for bench use in machining, fabrication, and mechanical trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo power source or mechanical installation is required for this hand tool set. Keep reference surfaces clean and free of burrs or debris before use to maintain measurement accuracy. Store pieces in the provided case when not in use to protect ground surfaces from damage. Calibration should be verified periodically against a known reference standard in critical inspection applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiece Count\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Lengths\u003c\/strong\u003e: 3\/4 inches, 1-1\/8 inches, 1-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Lengths\u003c\/strong\u003e: 1 inch, 1-1\/2 inches, 1-9\/16 inches, 2-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hardened and Ground Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 3 Beveled Squares, 1 Triangular Straight Edge, Protective Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6 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: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12-497-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51702481912114,"sku":"12-497-4","price":167.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28f5126d9e2c10ab3d628f75fd98ddcc.jpg?v=1788411288","url":"https:\/\/voomisupply.com\/products\/spi-12-497-4-square-set-4-piece-hardened-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
