Gage blocks at this grade are used as dimensional reference standards in metrology labs, tool rooms, and quality control departments where verified, traceable measurement is required. Each block ships with a Certificate of Inspection confirming conformance to the stated grade. This part is handled by machinists, metrologists, and QC technicians who require reliable, calibration-grade reference artifacts for setting instruments, verifying part dimensions, and qualifying fixtures.\u003c\/p\u003e\n\u003cp\u003eGrade AS-1 gage blocks are suited for general inspection and tool-room work where tighter laboratory-grade tolerances are not required. This block is appropriate for use in setting comparative measuring instruments such as dial indicators, height gages, and snap gages. It is also used for machine setup and fixture verification in both job-shop and production environments. The 0.125-inch size is a common increment in imperial gage block sets and is frequently used as a standalone reference block or combined with other blocks in a wringing stack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade AS-1 accuracy per ASME standards, with Certificate of Inspection included\u003c\/li\u003e\n  \u003cli\u003eNominal length of 0.125 inches (0.12500 decimal inch) for precise dimensional reference\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear in tool-room use\u003c\/li\u003e\n  \u003cli\u003eRectangular form compatible with standard gage block accessories and wringing fixtures\u003c\/li\u003e\n  \u003cli\u003eIndividual block sold as a single unit, suitable for supplementing or replacing a block in an existing set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style individual replacement or supplemental block for use in imperial rectangular gage block sets conforming to ASME standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks should be handled by metrology technicians or qualified tool-room personnel following established dimensional metrology procedures. Blocks must be cleaned and dried thoroughly before wringing or use to prevent corrosion and ensure accurate contact. Store in a controlled environment away from temperature extremes, vibration, and contaminants to maintain calibration integrity. Do not drop, stack unsupported, or use as a structural spacer outside of their intended measurement application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Length\u003c\/strong\u003e: 0.125 inches (0.12500 decimal inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: AS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME\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\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertificate of Inspection\u003c\/strong\u003e: Included\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: 611165-541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51557437342002,"sku":"611165-541","price":35.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8cddc77baf03dc3c9ce80805f4a4c2e3.jpg?v=1786388137","url":"https:\/\/voomisupply.com\/products\/mitutoyo-611165-541-steel-gage-block-0-125-in-grade-as-1","provider":"Voomi Supply","version":"1.0","type":"link"}
