Gage blocks are precision reference standards used to calibrate measuring instruments and set comparators to a known dimension. This block is machined from steel and includes a Certificate of Inspection, verifying that it meets the dimensional tolerances required for Grade AS-1 classification. Metrology technicians, quality control inspectors, and tool room machinists rely on gage blocks like this one for high-accuracy measurement verification in production and laboratory environments.\u003c\/p\u003e\n\u003cp\u003eThis gage block is suited for use in dimensional calibration labs, machine shops, and quality assurance departments where traceable measurement standards are required. It functions as a length reference for setting micrometers, height gauges, and other precision instruments. Its compact 0.143-inch size makes it a practical addition to a gage block set or a standalone reference standard for specific inspection routines. The included Certificate of Inspection supports documentation requirements in ISO-compliant quality systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade AS-1 accuracy per ASME standards, suitable for calibration and inspection use\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.143-inch nominal length with 5-decimal precision specification\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Inspection for traceability documentation\u003c\/li\u003e\n  \u003cli\u003eRectangular block geometry compatible with standard wringing techniques\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision reference standard for use with standard rectangular gage block accessories including holders, jaws, and scribing blocks commonly used in dimensional metrology applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks should be handled by metrology technicians or qualified inspection personnel following established calibration procedures. Clean and degrease all mating surfaces before wringing blocks together to avoid measurement error and surface damage. Store blocks in their protective case when not in use to prevent corrosion and surface wear. Periodic recalibration against a national standard is recommended to maintain traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: AS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.143 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 611183-541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51564319211826,"sku":"611183-541","price":35.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35c421855cd0ce7cbe04b9cce510b902.jpg?v=1786517210","url":"https:\/\/voomisupply.com\/products\/mitutoyo-611183-541-steel-gage-block-0-143-in-grade-as-1","provider":"Voomi Supply","version":"1.0","type":"link"}
