Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy on the shop floor or in the calibration lab. This block ships with NIST certification documentation, confirming traceability to national measurement standards. The steel construction provides long-term dimensional stability under normal workshop conditions. Grade 0 designation indicates a high level of flatness, parallelism, and length accuracy, making it appropriate for calibration and inspection tasks that demand reliable, repeatable measurements.\u003c\/p\u003e\n\u003cp\u003eThis gage block is suited for use in machine shops, tool rooms, quality control labs, and metrology environments. It serves as a reference standard for setting up surface plates, calibrating micrometers, dial indicators, and height gages, and verifying part dimensions against a known standard. The 0.3-inch size fills a specific slot in a gage block set or functions as a standalone reference for setups requiring that precise dimension. Machinists, quality technicians, and metrologists are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy for high-precision calibration and inspection work\u003c\/li\u003e\n  \u003cli\u003eSteel construction for dimensional stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eNominal size of 0.3 inches (0.30000 inches to five decimal places)\u003c\/li\u003e\n  \u003cli\u003eIncludes NIST certification for measurement traceability\u003c\/li\u003e\n  \u003cli\u003eSquare geometry allows consistent wringing and stable surface contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone Grade 0 steel gage block suitable for use with standard gage block accessories and holders in calibration and dimensional inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Before use, inspect the measuring faces for burrs or surface damage and clean with an appropriate gage block cleaning solution. Store the block in its protective case when not in use to prevent thermal variation and surface wear. Gage block calibration intervals should follow the requirements of the applicable quality management system or metrology program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize (Decimal Inch)\u003c\/strong\u003e: 0.30000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: Grade 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST Certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGeometry\u003c\/strong\u003e: Square\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 630-73306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709404119346,"sku":"630-73306","price":52.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/286b7b459fa3968a4f823865b8136585.jpg?v=1788455934","url":"https:\/\/voomisupply.com\/products\/value-collection-630-73306-square-steel-gage-block-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
