Each block is individually serialized and ships with an inspection certificate, supporting traceability requirements in calibration and quality assurance environments. Tolerances are tightly controlled across the range: 18 microinches for blocks from 0.05 to 0.4 inches, 24 microinches from 0.45 to 1 inch, 32 microinches at 2 inches, 40 microinches at 3 inches, and 48 microinches at 4 inches. The set is stored in a fitted wooden case for organization and protection between uses.\u003c\/p\u003e\u003cp\u003eThis set is suited for dimensional inspection, machine setup, calibration of measuring instruments, and surface plate work in manufacturing and metrology environments. The step increments cover four series: 19 blocks at 0.05-inch steps, 4 blocks at 1.000-inch steps, 49 blocks at 0.001-inch steps, and 9 blocks at 0.0001-inch steps, providing broad combination capability. Typical users include machinists, quality control technicians, tool and die makers, and calibration lab personnel working in industrial or production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e81-piece set covering 0.05 to 4 inches with four step-increment series for wide combination range\u003c\/li\u003e\n\u003cli\u003eAS-2 accuracy grade per ASME B89.1.9-2002 standard\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and wringing compatibility\u003c\/li\u003e\n\u003cli\u003eIndividually serialized blocks with included inspection certificate for traceability\u003c\/li\u003e\n\u003cli\u003eTolerances specified per size range: 18 to 48 microinches depending on block length\u003c\/li\u003e\n\u003cli\u003eFitted wooden storage case included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision gage block set for use with standard surface plate and gage block accessories conforming to ASME B89.1.9-2002.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGage blocks are precision metrology tools and do not require mechanical installation, but proper handling procedures apply. Blocks should be wrung together on a clean, flat surface free of burrs and contaminants. Store blocks in the provided wooden case when not in use to prevent corrosion and surface damage. Calibration intervals should follow the requirements of the applicable quality management system or laboratory accreditation standard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: AS-2\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\u003eNumber of Pieces\u003c\/strong\u003e: 81\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.05 to 4 inches\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: 18 microinches (0.05 to 0.4 in), 24 microinches (0.45 to 1 in), 32 microinches (2 in), 40 microinches (3 in), 48 microinches (4 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: (19) 0.05 inch, (4) 1.000 inch, (49) 0.001 inch, (9) 0.0001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Inspection Certificate, Wooden Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndividually Serialized\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10 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: 516-904-26\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563167351090,"sku":"516-904-26","price":2098.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8addaf6bc8e88d4a5829cf7132e83a2.jpg?v=1786492045","url":"https:\/\/voomisupply.com\/products\/mitutoyo-516-904-26-gage-block-set-81-pc-as-2-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
