Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in the metrology lab. This block ships with NIST certification documentation, confirming traceability to national measurement standards. Grade AS-1 meets the tolerance requirements for inspection-grade work, making it suitable for use in quality control environments where instrument calibration and dimensional verification demand tight accuracy.\u003c\/p\u003e\n\u003cp\u003eThis gage block is used in manufacturing, machining, and metrology environments wherever a traceable dimensional reference standard is required. Typical applications include calibrating micrometers, dial indicators, and height gages, as well as setting up fixtures and inspection routines. It is appropriate for both shop-floor use and controlled metrology lab environments. The block is sold individually, allowing technicians and calibration specialists to replace a single worn or damaged block within an existing set without purchasing a full set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal size of 0.123 inches ground to Grade AS-1 accuracy tolerances\u003c\/li\u003e\n  \u003cli\u003eIncludes NIST certification for full traceability to national standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and wear resistance under repeated use\u003c\/li\u003e\n  \u003cli\u003eRectangular form compatible with standard gage block accessories and holders\u003c\/li\u003e\n  \u003cli\u003eSold as a single block for individual replacement or standalone calibration use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standalone reference standard compatible with rectangular gage block sets and accessories that accept 0.123-inch nominal blocks conforming to Grade AS-1 tolerances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled and stored by metrology technicians and calibration specialists. Always clean block surfaces with an appropriate solvent and lint-free cloth before use to prevent debris from affecting accuracy readings. Store blocks in a protective case away from humidity and temperature extremes to prevent corrosion and dimensional drift. Do not drop or wring blocks forcefully, as steel gage blocks are precision ground and susceptible to surface damage that compromises accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 0.123 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: AS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 15-037-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51727480160562,"sku":"15-037-5","price":23.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e8eeb5c483d34d44db317910304f5a3_57a7c1f1-ca54-4bee-a6b9-fdc5590d5f88.jpg?v=1788678376","url":"https:\/\/voomisupply.com\/products\/spi-15-037-5-steel-gage-block-0-123-in-grade-as-1","provider":"Voomi Supply","version":"1.0","type":"link"}
