Gage blocks serve as primary length reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in precision machining and inspection environments. This block ships with NIST certification, confirming its dimensional accuracy has been verified against national measurement standards. Grade 0 represents a high-accuracy classification suitable for tool room and metrology lab applications. Inspection technicians, machinists, and quality control professionals rely on certified gage blocks as the foundation of dimensional traceability in any shop or lab environment.\u003c\/p\u003e\n\u003cp\u003eThis gage block is suited for use in tool rooms, quality inspection labs, and precision manufacturing environments where traceable dimensional standards are required. The NIST certification included with this block supports ISO 9001 and other quality management programs that require documented measurement traceability. It is appropriate for setting dial indicators, height gages, snap gages, and similar instruments requiring a known reference dimension. Both industrial and calibration lab settings benefit from Grade 0 certified blocks as master reference standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy classification for high-precision tool room and metrology applications\u003c\/li\u003e\n  \u003cli\u003eNominal size of 1.00000 inches with tight dimensional tolerances consistent with Grade 0 specification\u003c\/li\u003e\n  \u003cli\u003eNIST certification included, supporting measurement traceability requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under normal shop conditions\u003c\/li\u003e\n  \u003cli\u003eRectangular block geometry compatible with standard gage block accessories and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style reference standard compatible with standard rectangular gage block sets and accessories used in precision measurement and calibration applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled and stored by metrology technicians and precision inspection personnel following established gauge care procedures. Blocks should be cleaned with an appropriate solvent and lint-free cloth before and after use to prevent corrosion and surface contamination. Store blocks in their protective case away from temperature extremes, humidity, and vibration sources to maintain dimensional stability. Never drop or stack blocks on hard surfaces without protective interleaving, as surface damage directly affects accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\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: 1.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification Standard\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 611201-531CAL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558186058034,"sku":"611201-531CAL","price":76.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/081cbc78f9dd76e7cb58bc428ad19cd2.jpg?v=1786405684","url":"https:\/\/voomisupply.com\/products\/mitutoyo-611201-531cal-steel-gage-block-1-inch-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
