The blade measures 4 inches in length and the base measures 3 inches, providing a compact and rigid inspection tool suited for workbench and machine-side use. A beveled edge on the blade allows the square to seat cleanly against a workpiece for precise line scribe and gap-light checking. Accuracy is rated at 0.0001 inches, making this square appropriate for close-tolerance fitting and inspection tasks. The matte finish reduces glare under shop lighting. Machinists, tool-and-die technicians, and precision fabricators are the primary users of this type of square.\u003c\/p\u003e\n\u003cp\u003eThis square is built for layout and measurement applications across machine shops, fabrication environments, and tool rooms. The compact 4-inch blade and 3-inch base combination suits part inspection, setup verification, and scribing tasks on smaller workpieces. The tool steel construction holds calibration under repeated shop use and resists wear against metal workpiece edges. It is appropriate for both bench-level quality checks and setup tasks at mills, lathes, and surface plates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 inch blade length for compact right-angle reference on smaller workpieces\u003c\/li\u003e\n  \u003cli\u003e3 inch base length provides stable footing against workpiece edges\u003c\/li\u003e\n  \u003cli\u003e0.0001 inch accuracy rating for close-tolerance layout and inspection\u003c\/li\u003e\n  \u003cli\u003eBeveled blade edge allows clean seating and gap-light inspection technique\u003c\/li\u003e\n  \u003cli\u003eTool steel construction resists wear and holds calibration in shop conditions\u003c\/li\u003e\n  \u003cli\u003eMatte finish reduces glare for accurate visual alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard precision square for layout and measurement work across general machining, fabrication, and inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachinists and precision layout technicians handle this tool as part of setup and inspection routines. No power source or fasteners are required. Keep the blade and base surfaces clean and free of chips or burrs before referencing against a workpiece to avoid false readings. Store the square in a protected case or dedicated slot to prevent damage to the ground surfaces and maintain accuracy between uses.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBevel Edge\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Matte\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Layout and Measurement Work\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111803\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: FOWLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52-426-004-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67908111335730,"sku":"52-426-004-0","price":112.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecfae1b34df0be92467402d2421e08b8_1a95c17c-b52c-42e4-8777-f82d1f7449ac.jpg?v=1791182511","url":"https:\/\/voomisupply.com\/products\/fowler-52-426-004-0-tool-steel-square-4-inch-blade","provider":"Voomi Supply","version":"1.0","type":"link"}
