At 4.00000 inches in nominal size, this block delivers the tight dimensional tolerances required for calibrating measuring instruments, setting comparators, and verifying part dimensions on the shop floor or in a quality lab. A Certificate of Inspection is included, documenting traceable accuracy to ASME standards. This type of gage block is handled by metrology technicians, quality engineers, and precision machinists.\u003c\/p\u003e\n\u003cp\u003eGrade 0 gage blocks are suited for toolroom and laboratory applications where higher accuracy is required compared to working-grade blocks. The 4-inch size is commonly used as a reference standard for large-span measurements, height gage setup, and surface plate work. This block is appropriate for both incoming inspection stations and in-process gauging in precision manufacturing environments where dimensional traceability to ASME standards is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy per ASME standards, suitable for toolroom and laboratory reference use\u003c\/li\u003e\n  \u003cli\u003eNominal size of 4.00000 inches for large-span measurement setup and verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability under normal shop conditions\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Inspection for traceable calibration documentation\u003c\/li\u003e\n  \u003cli\u003eASME-compliant for use in regulated quality management and inspection programs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision reference standard compatible with standard gage block accessories including holders, jaws, and scribers conforming to ASME B89.1.9 gage block system requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled by metrology technicians and quality personnel, not installed in mechanical systems. Before use, allow the block to stabilize at ambient temperature, typically 68 degrees F, to minimize thermal expansion error. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in the provided case when not in use to protect lapped surfaces from damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: Grade 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Certificate of Inspection\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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 614204-531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558440862002,"sku":"614204-531","price":183.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e4422718b291e2f0445e21599e3909d.jpg?v=1786412414","url":"https:\/\/voomisupply.com\/products\/mitutoyo-614204-531-square-steel-gage-block-4-in-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
