It is built to Accuracy Grade 00, the highest grade defined under ASME B89.1.9-2002, making it suitable for laboratory-grade dimensional reference and precision calibration work. Each block is individually serialized and ships with an inspection certificate, supporting traceability requirements in quality and metrology environments. The set is housed in a wooden storage case. Tolerances are 3 micro-inches for blocks in the 0.05 to 1 inch range, 4 micro-inches for 2-inch blocks, and 6 micro-inches for the 4-inch block. Machinists, metrologists, and quality technicians are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis set is designed for precision measurement applications in manufacturing, tool-and-die, inspection, and calibration lab environments. The 81-piece configuration provides a complete working set for building a wide range of stack dimensions. Step increments include 49 blocks at 0.001-inch steps, 9 blocks at 0.0001-inch steps, 19 blocks at 0.05-inch steps, and 4 blocks at 1.000-inch steps. This combination supports virtually any dimensional reference requirement within the 0.101 to 4 inch range. The set is appropriate for both shop floor and controlled-environment use, particularly where Grade 00 traceability is required by quality management systems or customer specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccuracy Grade 00 per ASME B89.1.9-2002 — highest classification for gage block precision\u003c\/li\u003e\n\u003cli\u003e81-piece set covering 0.101 to 4 inches with four step increment series\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n\u003cli\u003eEach block individually serialized for traceability\u003c\/li\u003e\n\u003cli\u003eIncludes inspection certificate for quality system documentation\u003c\/li\u003e\n\u003cli\u003eWooden case included for organized storage and protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose Grade 00 steel gage block set for use with standard gage block accessories and holders conforming to ASME B89.1.9-2002 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGage blocks should be handled by metrology technicians or qualified quality personnel following proper wringing technique to avoid surface damage. Blocks must be stored clean and dry; contact with abrasive surfaces, corrosive chemicals, or unprotected metal can affect calibrated surfaces. Allow blocks to thermally stabilize to the measurement environment before use. Periodic recalibration intervals should comply with the applicable quality management system requirements and ASME standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: 00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Size\u003c\/strong\u003e: 0.101 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Size\u003c\/strong\u003e: 4.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 81\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 3 micro-inches (0.05 to 1 inch range); 4 micro-inches (2 inch); 6 micro-inches (4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: (49) 0.001 inch; (9) 0.0001 inch; (19) 0.05 inch; (4) 1.000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1.9-2002\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndividually Serialized\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Inspection certificate, wooden case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 516-901-26\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51557778850098,"sku":"516-901-26","price":5311.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d246935bfdbf75c163cf2e9fc6edbc9.jpg?v=1786394956","url":"https:\/\/voomisupply.com\/products\/mitutoyo-516-901-26-gage-block-set-81-pc-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
