Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in the metrology lab. This block conforms to ASME standards and ships with a Certificate of Inspection, confirming that it has been measured and documented to Grade 0 tolerances. Grade 0 blocks are suited for laboratory and toolroom calibration work where tighter uncertainty budgets are required. Machinists, quality technicians, and metrologists are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis gage block is used in dimensional metrology applications across manufacturing, toolroom, and inspection environments. It is appropriate for setting height gages, bore gages, and snap gages, as well as for checking surface plate setups. The 0.21-inch size makes it a standard increment block for wringing into stacks to build up target dimensions. It is suitable for both incoming inspection and process control environments where traceability to a documented standard is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy per ASME standards for tight-tolerance calibration work\u003c\/li\u003e\n  \u003cli\u003eRectangular steel construction for durability and wringing compatibility\u003c\/li\u003e\n  \u003cli\u003e0.21-inch nominal length for use as a stack increment block\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Inspection for traceability documentation\u003c\/li\u003e\n  \u003cli\u003eASME-compliant for use in regulated inspection and quality environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision reference standard suitable for use with standard gage block accessory sets and wringing fixtures compatible with rectangular-style steel gage blocks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled and used by quality technicians and metrologists and require no mechanical installation. Clean measuring faces with a lint-free cloth and appropriate solvent before wringing to remove oils and debris. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Do not drop or stack blocks carelessly, as surface damage will affect accuracy and render calibration documentation invalid.\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\u003eOverall Length\u003c\/strong\u003e: 0.21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\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\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: 611221-531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559097139506,"sku":"611221-531","price":52.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f958dfe3b3121bdc49c85c87f43c1349_afa6a8e3-a8bd-4923-9966-53a62ae4defe.jpg?v=1786427449","url":"https:\/\/voomisupply.com\/products\/mitutoyo-611221-531-steel-gage-block-0-21-in-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
