Gage blocks of this type serve as primary length reference standards used to calibrate measuring instruments, verify machine setups, and establish precise dimensional benchmarks in metrology labs and production environments. Grade 0 blocks meet ASME standards and are intended for applications requiring tight tolerance verification. The block ships with a Certificate of Inspection, confirming traceability to recognized dimensional standards. Weight is approximately 1 pound.\u003c\/p\u003e\n\u003cp\u003eThis gage block is suited for calibration laboratories, tool rooms, and precision manufacturing facilities where dimensional reference accuracy is critical. Metrologists, quality technicians, and toolroom machinists use Grade 0 blocks for instrument calibration and inspection setups. The 12-inch nominal length makes this block appropriate for longer-range setups such as height gauge calibration, linear standard verification, and machine tool alignment checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy per ASME standards for high-precision metrology work\u003c\/li\u003e\n  \u003cli\u003e12.00000-inch nominal length for long-range dimensional reference\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Inspection for traceability documentation\u003c\/li\u003e\n  \u003cli\u003eRectangular form 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 rectangular gage block for use with standard gage block sets, holders, and accessories conforming to ASME B89.1.9 rectangular block geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled and stored by metrology technicians and toolroom personnel. Before use, blocks should be cleaned with an appropriate solvent to remove storage oil and allowed to thermally stabilize at the reference temperature of 68 degrees F (20 degrees C) per ASME standards. Avoid contact with abrasive surfaces and do not stack or wring blocks without proper technique, as surface damage will affect accuracy. Store in the supplied case to protect lapped faces from contamination and corrosion.\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 Length\u003c\/strong\u003e: 12.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 611223-531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559204880690,"sku":"611223-531","price":850.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f958dfe3b3121bdc49c85c87f43c1349_1a06d63a-7912-4ae1-8232-c688bafffce7.jpg?v=1786429818","url":"https:\/\/voomisupply.com\/products\/mitutoyo-611223-531-steel-gage-block-12-in-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
