The set covers a range of 0.05 to 4 inches using four step-increment series: 49 blocks at 0.001-inch increments, 19 blocks at 0.05-inch increments, 9 blocks at 0.0001-inch increments, and 4 blocks at 1.000-inch increments. NIST NVLAP traceability certification is included with the set. Precision metrology technicians, tool-and-die makers, machinists, and quality control inspectors use this set to calibrate measuring instruments, set comparators, and verify dimensional tolerances on machined components.\u003c\/p\u003e\u003cp\u003eThis gage block set is suited for dimensional inspection and calibration work in machine shops, tool rooms, and quality laboratories. The broad increment range — from fine 0.0001-inch steps to full 1-inch blocks — allows technicians to build virtually any reference dimension within the set's range. The Grade 0 classification indicates a high level of flatness, parallelism, and length accuracy appropriate for production and inspection applications where measurement traceability to national standards is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e81 total pieces covering 0.05 to 4 inches in four increment series\u003c\/li\u003e\n\u003cli\u003eGrade 0 accuracy per ASME B89.1.9-2002\u003c\/li\u003e\n\u003cli\u003eFine 0.0001-inch increment blocks for high-resolution reference stacking\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and consistent dimensional stability\u003c\/li\u003e\n\u003cli\u003eNIST NVLAP traceability certification included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose reference standard compatible with standard gage block accessories and holders used in dimensional metrology and calibration applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGage blocks should be handled only by trained metrology or machining personnel using clean, lint-free gloves or finger cots to prevent contamination and corrosion. Before wringing blocks together, clean each mating surface thoroughly with an approved instrument-grade solvent and a lint-free cloth. Store blocks in the provided case in a temperature-stable environment and allow thermal soak time when moving between environments with different temperatures. Never drop or strike blocks against hard surfaces, as this will damage the lapped faces and invalidate calibration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 81\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRange\u003c\/strong\u003e: 0.05 to 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: (49) 0.001 inch; (19) 0.05 inch; (9) 0.0001 inch; (4) 1.000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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, NIST NVLAP Traceability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 92845\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544132813106,"sku":"92845","price":7990.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c79e2d823d968788caba6fa5632771e7.jpg?v=1785924614","url":"https:\/\/voomisupply.com\/products\/starrett-92845-grade-0-steel-gage-block-set-81-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
