Gage blocks of this grade serve as dimensional reference standards used to calibrate measuring instruments, set comparators, and verify part dimensions to tight tolerances. Each block ships with a Certificate of Inspection, confirming it has been measured and documented at the factory. Grade 0 blocks are suited for metrology labs, quality departments, and precision machining environments where traceable dimensional standards are required. Installation and handling are performed by metrologists, quality technicians, and precision machining professionals.\u003c\/p\u003e\u003cp\u003eThis 0.128-inch gage block is used in dimensional metrology applications across manufacturing, tool and die, aerospace, and general precision machining environments. It functions as a standalone reference standard or as part of a set used to build up specific dimensions by wringing blocks together. Typical use cases include calibrating micrometers, calipers, and height gages, as well as setting dial indicator comparators on surface plates. The steel construction provides the durability and stability required for repeated use in workshop and laboratory settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNominal length of 0.128 inches for precise dimensional reference\u003c\/li\u003e\n\u003cli\u003eGrade 0 accuracy per ASME standards, suitable for lab and quality-control use\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and long-term dimensional stability\u003c\/li\u003e\n\u003cli\u003eIncludes a Certificate of Inspection for traceability documentation\u003c\/li\u003e\n\u003cli\u003eSquare geometry allows wringing with other gage blocks to build up compound dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style dimensional reference standard compatible with standard gage block sets and accessories used in ASME-compliant metrology applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGage blocks should be handled by metrology technicians or quality professionals using lint-free gloves to prevent surface contamination and corrosion from skin oils. Before use, clean block surfaces with an appropriate solvent and inspect for burrs or wear that could affect accuracy. Store blocks in their protective case when not in use to prevent damage to lapped surfaces. Follow ASME B89.1.9 handling and care guidelines to maintain grade-level accuracy over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Length\u003c\/strong\u003e: 0.128 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: ASME\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Certificate of Inspection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 614168-531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51564209176882,"sku":"614168-531","price":51.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a41db2f375a4d1c3f7e120b5effc0c20.jpg?v=1786514304","url":"https:\/\/voomisupply.com\/products\/mitutoyo-614168-531-square-steel-gage-block-0-128-in-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
