Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional accuracy on the shop floor or in the metrology lab. This block includes NIST certification, providing traceability to national measurement standards. Grade AS-1 denotes a high level of dimensional accuracy and surface flatness, making it suitable for demanding inspection and calibration work in industrial and trade environments.\u003c\/p\u003e\n\u003cp\u003eThis gage block is used in precision measurement applications across manufacturing, machining, tool-and-die, and mechanical inspection settings. Machinists, quality control technicians, and calibration specialists use blocks like this one to verify instrument accuracy, establish reference datums, and perform direct comparison measurements. The 0.40000-inch nominal size makes it a practical addition to an incremental gage block set or a standalone reference standard for specific dimensional checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade AS-1 accuracy for high-precision calibration and inspection use\u003c\/li\u003e\n  \u003cli\u003eNominal size of 0.40000 inches with five-decimal inch designation\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and long-term dimensional stability\u003c\/li\u003e\n  \u003cli\u003eIncludes NIST certification providing traceable measurement standards\u003c\/li\u003e\n  \u003cli\u003eRectangular form for easy wringing and stacking with other gage blocks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision reference standard compatible with standard rectangular gage block sets used in general metrology and dimensional inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks should be handled by calibration technicians or qualified metrology personnel using appropriate lint-free gloves to prevent contamination and corrosion. Clean block surfaces thoroughly before and after use using approved solvents and store in a protective case to maintain surface integrity. Do not drop or impact the block, as even minor surface damage can compromise accuracy. Follow your facility calibration procedures and applicable ASME B89.1.9 standards when using gage blocks in a measurement traceability program.\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\u003eSize (Decimal Inch)\u003c\/strong\u003e: 0.40000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: AS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST Certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 630-33406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715982360882,"sku":"630-33406","price":37.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd6f0012382fc2902709ea41b7d0245f.jpg?v=1788520554","url":"https:\/\/voomisupply.com\/products\/value-collection-630-33406-steel-gage-block-0-4-in-grade-as-1","provider":"Voomi Supply","version":"1.0","type":"link"}
