These blocks cover a measurement range of 0.05 to 4 inches across four step increment groups, giving technicians the combination capability to build a wide range of precise reference dimensions. A NIST NVLAP traceability certification is included, making the set suitable for calibration labs, tool rooms, and quality control environments where documented measurement standards are required. Precision machinists, metrology technicians, and QC inspectors are the primary users of this set.\u003c\/p\u003e\n\u003cp\u003eThis gage block set is appropriate for both shop-floor and laboratory use where high-accuracy dimensional reference is needed. The four increment groups include 49 blocks in 0.001-inch steps, 19 blocks in 0.05-inch steps, 9 blocks in 0.0001-inch steps, and 4 blocks in 1.000-inch steps, providing flexible combination coverage across the full range. Typical applications include setting comparators, calibrating micrometers and calipers, and verifying fixture dimensions in manufacturing and metrology settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy per ASME B89.1.9-2002 for high-precision measurement reference\u003c\/li\u003e\n  \u003cli\u003e81-piece set spanning 0.05 to 4 inches across four step increment groups\u003c\/li\u003e\n  \u003cli\u003eIncludes 49 blocks at 0.001-inch increments, 9 at 0.0001-inch increments, 19 at 0.05-inch increments, and 4 at 1.000-inch increments\u003c\/li\u003e\n  \u003cli\u003eRectangular steel construction for durability and long-term dimensional stability\u003c\/li\u003e\n  \u003cli\u003eNIST NVLAP traceability certification included for documented compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Grade 0 gage block set compatible with standard wringing and stacking practices used with rectangular steel gage blocks in tool room, calibration lab, and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks should be handled by metrology or QC personnel trained in proper wringing technique to avoid damage to lapped surfaces. Store blocks in a controlled-temperature environment and allow thermal stabilization before use to ensure measurement accuracy. Clean blocks with an appropriate gage oil or calibration-grade solvent before and after use. Do not drop or strike blocks against hard surfaces, as this will damage the precision lapped faces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eAccuracy Grade\u003c\/strong\u003e: Grade 0\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlock Shape\u003c\/strong\u003e: Rectangular\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\u003c\/strong\u003e: NIST NVLAP Traceability Certification included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14 pounds\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 92913\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541718827314,"sku":"92913","price":3804.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/595f9cca24135f9a552733cceb2dcc34.jpg?v=1785882960","url":"https:\/\/voomisupply.com\/products\/starrett-92913-steel-gage-block-set-grade-0-81-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
