Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in a metrology lab. This block conforms to ASME B89.1.9 Grade AS-1, one of the highest accuracy tiers in the standard, making it appropriate for laboratory-grade calibration work. A Certificate of Inspection is included, providing traceable documentation of the block's dimensional accuracy at the time of manufacture.\u003c\/p\u003e\n\u003cp\u003eThis gage block is suited for use in tool rooms, metrology labs, and quality control environments where precise length references are required. Typical applications include setting dial indicators and electronic gages, calibrating micrometers and vernier instruments, and establishing datum references for surface plate inspection setups. The 0.115-inch nominal size fits into standard gage block sets and wringing stacks. It is used by quality technicians, metrologists, machinists, and precision measurement professionals across manufacturing and inspection operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade AS-1 accuracy per ASME B89.1.9 — suitable for laboratory and calibration-grade metrology work\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and stable dimensional characteristics over time\u003c\/li\u003e\n  \u003cli\u003e0.115-inch nominal size for use as a single reference block or within a wringing stack\u003c\/li\u003e\n  \u003cli\u003eCertificate of Inspection included for traceable dimensional documentation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME standards, supporting compliance with calibration program requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style rectangular gage block compatible with standard gage block sets, wringing accessories, and holders designed for single-piece rectangular blocks of comparable size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are handled and stored by metrology technicians following established laboratory procedures. Blocks should be stored in their protective case when not in use to prevent corrosion and surface damage. Before use, clean block surfaces with an appropriate gage block cleaner and lint-free cloth. When wringing blocks together, apply light pressure and a sliding motion — never force or slam blocks, as this can damage the lapped surfaces and affect accuracy.\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\u003eNominal Size\u003c\/strong\u003e: 0.115 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\u003eStandards\u003c\/strong\u003e: ASME\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: 611155-541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51560796291378,"sku":"611155-541","price":35.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f958dfe3b3121bdc49c85c87f43c1349_61cdddfe-d681-444c-9d2e-75f2e7f7e9ee.jpg?v=1786457740","url":"https:\/\/voomisupply.com\/products\/mitutoyo-611155-541-steel-gage-block-0-115-in-grade-as-1","provider":"Voomi Supply","version":"1.0","type":"link"}
