Gage blocks at this grade deliver tight dimensional tolerances suitable for calibration work, tool room inspection, and precision layout tasks. Each block includes NIST certification documentation, providing traceable measurement accuracy required in regulated manufacturing and metrology environments. Licensed machinists, tool and die makers, and quality control technicians rely on this type of precision reference standard for setting comparators, calibrating measuring instruments, and verifying part dimensions on the shop floor or in the inspection lab.\u003c\/p\u003e\n\u003cp\u003eThis gage block is suited for use in tool rooms, calibration labs, and quality inspection stations where traceable measurement references are required. Its 2-inch nominal size makes it a practical reference block for medium-range dimensional verification. The included NIST certification supports use in facilities subject to ISO, AS9100, or similar quality management standards that require documented measurement traceability. It is appropriate for both production-floor spot checks and formal calibration procedures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy for demanding calibration and precision inspection applications\u003c\/li\u003e\n  \u003cli\u003eNominal size of 2.00000 inches for medium-range dimensional reference\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability over time\u003c\/li\u003e\n  \u003cli\u003eIncludes NIST certification for traceable measurement documentation\u003c\/li\u003e\n  \u003cli\u003eRectangular form allows wringing to other gage blocks for combination setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision reference block compatible with standard gage block sets and wring-compatible rectangular block accessories used in tool room and metrology applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled and stored by calibration technicians and precision machinists following standard metrology practices. Blocks should be cleaned of oils and debris before wringing or use, and stored in a protective case away from humidity to prevent corrosion of the steel surface. Do not drop or stack blocks in ways that risk edge damage, as surface integrity directly affects measurement accuracy. Periodic recertification intervals should follow the requirements of the applicable quality management system.\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: 2.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: Grade 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification Standard\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12-718-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714235728178,"sku":"12-718-3","price":61.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19a3122876d9b1ab039f06330e870e06.jpg?v=1788498023","url":"https:\/\/voomisupply.com\/products\/spi-12-718-3-steel-gage-block-2-inches-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
