These blocks are used to establish precise dimensional reference points during calibration, inspection, and machine setup work. The set spans a range of 1\/16 to 2 inches and conforms to ASME B89.1.9-2002 dimensional standards. A NIST NVLAP traceability certification is included, making this set suitable for quality-controlled environments where documented measurement traceability is required. Machinists, metrologists, and precision tool calibration technicians are the primary users of this type of tooling.\u003c\/p\u003e\u003cp\u003eThis gage block set is used in manufacturing, maintenance, and inspection settings where tight dimensional tolerances must be verified or set. Typical applications include calibrating measuring instruments, setting up machine tools, and verifying part dimensions against a known reference. The Grade 0 accuracy classification positions this set for general-purpose precision work in both shop floor and calibration lab environments. The rectangular block geometry is the standard form for most bench and gauge calibration tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 0 accuracy per ASME B89.1.9-2002 for reliable dimensional reference\u003c\/li\u003e\n\u003cli\u003e9-piece set covering 1\/16 to 2 inches range\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and long-term dimensional stability\u003c\/li\u003e\n\u003cli\u003eIncludes NIST NVLAP traceability certification for documented calibration compliance\u003c\/li\u003e\n\u003cli\u003eRectangular block geometry compatible with standard gage block accessories and holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision reference set compatible with standard rectangular gage block holders, surface plates, and calibration fixtures used in general metrology and machine shop applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGage blocks should be handled by qualified calibration or metrology technicians using clean, lint-free gloves to prevent surface contamination and corrosion. Store blocks in the provided case when not in use and keep them away from magnetic fields and temperature extremes that could affect accuracy. Wring blocks together using a clean, flat surface and approved wringing technique to achieve proper contact before use. Follow facility calibration procedures and applicable metrology standards when placing these blocks into service as reference standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRange\u003c\/strong\u003e: 1\/16 to 2 inches\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\u003eBlock Geometry\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 Included\u003c\/strong\u003e: NIST NVLAP Traceability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 92939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544177967410,"sku":"92939","price":628.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/460a358777dbf1cf4cfc3636f9943a47.jpg?v=1785925288","url":"https:\/\/voomisupply.com\/products\/starrett-92939-steel-gage-block-set-grade-0-9-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
