The gage checks that a threaded hole falls within the allowable tolerance on the tight side, confirming the thread will accept a mating fastener without interference. Built to 6H classification, it conforms to ANSI standards and is traceable to NIST, making it suitable for quality inspection environments where documentation matters. The handle is not included and must be sourced separately. At 0.22 pounds, the gage is compact and easy to use at the bench or on the floor.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in machining, fabrication, assembly, and quality control applications where M12x1.75 metric threads must be verified before parts move to the next stage of production. It is appropriate for inspection of threaded holes in equipment housings, brackets, structural components, and mechanical assemblies across industrial and manufacturing settings. Machinists, quality technicians, and inspection personnel are the typical users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo gage confirms the threaded hole accepts a mating fastener — catches undersize or misformed threads\u003c\/li\u003e\n  \u003cli\u003eM12x1.75 metric thread size, 6H tolerance classification\u003c\/li\u003e\n  \u003cli\u003eANSI standard compliance with NIST traceability for documented inspection programs\u003c\/li\u003e\n  \u003cli\u003eSingle-end design — handle sold separately for flexible setup with existing handle stock\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 1.75 inches in length, 0.47 inches in width and height\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.22 pounds for easy bench or in-line use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any standard gage handle accepting plugs of this form factor.

Secure the gage in an appropriate handle before use. Keep the gage clean and lightly oiled when stored to prevent corrosion and maintain dimensional accuracy. Periodic re-certification against NIST-traceable masters is recommended to ensure continued inspection reliability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111619\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 37-117-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690566877490,"sku":"37-117-9","price":80.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/962699c336b9df36d73c9d8fbeedd003.jpg?v=1788271813","url":"https:\/\/voomisupply.com\/products\/spi-37-117-9-plug-thread-gage-m12x1-75-6h-go","provider":"Voomi Supply","version":"1.0","type":"link"}
