Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in machining and inspection environments. This block meets ASME standards and ships with a Certificate of Inspection, confirming it has been checked against traceable standards before leaving the factory. Grade 0 tolerance is tighter than Grade 1 and Grade AS-1, making this block suitable for inspection-room and toolroom applications where close dimensional control is required.\u003c\/p\u003e\n\u003cp\u003eThis gage block is used in metrology labs, tool cribs, and quality control departments across manufacturing, aerospace, automotive, and general machining facilities. A single 0.137-inch block covers setups requiring that specific decimal dimension or contributes to a combination stack. Machinists, metrologists, and quality technicians are the primary users. It is appropriate for both standalone reference use and as part of a larger gage block set being filled out or replaced piece by piece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy per ASME standards for tight tolerance inspection work\u003c\/li\u003e\n  \u003cli\u003e0.137-inch nominal size, precision-ground steel construction\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Inspection for traceability documentation\u003c\/li\u003e\n  \u003cli\u003eRectangular form for stable stacking and wringing with other gage blocks\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-block replacement or set supplementation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental piece for rectangular steel gage block sets requiring a 0.137-inch Grade 0 block conforming to ASME standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled by metrology technicians and quality control personnel, not installed in the field sense. Store blocks in a clean, dry environment and allow thermal stabilization before use. Clean contact faces with an appropriate gage block cleaning solution and lint-free cloth before wringing. Never drop or stack blocks carelessly, as nicked or corroded faces will compromise accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: Grade 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 0.137 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Certificate of Inspection\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 611177-531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51557307187506,"sku":"611177-531","price":44.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2be83c22e937cd8573600317c9d3b2a1.jpg?v=1786385621","url":"https:\/\/voomisupply.com\/products\/mitutoyo-611177-531-steel-gage-block-0-137-in-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
