The tool features a 3-inch blade length and a 2.5-inch base length, offering compact geometry suited for close-tolerance checking in confined setups. Parallel accuracy is held to 0.0006 inches and square accuracy to 0.0011 inches, meeting workshop-grade specifications. Machinists, toolmakers, and fabricators use this type of precision square for verifying right angles, setting up vises, and checking workpiece squareness at the bench or on the machine.\u003c\/p\u003e\u003cp\u003eThis square is designed for general workshop and light inspection use in metalworking shops, job shops, and trade environments where reliable angle reference is required. The compact blade-to-base ratio makes it practical for small-part setups and confined layout work. It is appropriate for use on machine tools, surface plates, and fabrication benches where workshop-grade accuracy is acceptable for the task.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch blade length for compact layout and angle checking\u003c\/li\u003e\n\u003cli\u003e2.5-inch base length provides stable seating on workpieces and reference surfaces\u003c\/li\u003e\n\u003cli\u003eParallel accuracy: 0.0006 inches\u003c\/li\u003e\n\u003cli\u003eSquare accuracy: 0.0011 inches\u003c\/li\u003e\n\u003cli\u003eManufactured to workshop-grade specifications\u003c\/li\u003e\n\u003cli\u003eSpring steel construction for durability and resistance to wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose workshop-grade square suitable for standard metalworking layout and inspection applications where 0.0006-inch parallel and 0.0011-inch square accuracy tolerances are appropriate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this hand tool. Clean the reference surface and base seating face before use to ensure accurate readings. Handle precision squares carefully to avoid dropping, which can alter calibration. Periodic verification against a known reference standard 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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParallel Accuracy\u003c\/strong\u003e: 0.0006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Accuracy\u003c\/strong\u003e: 0.0011 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Workshop Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 13-625-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693771751730,"sku":"13-625-9","price":21.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b41e09bda0d5f846a99588d29a6c8199.jpg?v=1788317170","url":"https:\/\/voomisupply.com\/products\/spi-13-625-9-spring-steel-square-3-in-blade-workshop-grade","provider":"Voomi Supply","version":"1.0","type":"link"}
