Designated as a No Go gage, it checks that an internally threaded hole does not exceed its maximum material condition, ensuring threads are not cut oversized or otherwise out of tolerance. The gage is manufactured from steel and conforms to ANSI and NIST standards, with a traceability certification included for documentation in quality systems. Licensed machinists, tool-and-die technicians, quality control inspectors, and precision manufacturing professionals use this type of gage as part of standard thread inspection protocol.\u003c\/p\u003e\n\u003cp\u003eThis gage is designed for use with 0-80 internal threads, a fine-pitch unified thread specification common in miniature fastener applications found in instrument assembly, electronics, medical devices, and small precision components. The 2B classification indicates a standard tolerance class for general-purpose unified internal threads. The gage accepts a Size 0 handle, which is sold separately. It is suited for both production floor inspection and incoming quality verification tasks where NIST-traceable documentation is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go function checks rejection boundary of internal thread tolerance per ANSI standards\u003c\/li\u003e\n  \u003cli\u003eCertified to NIST traceability standards with documentation included\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and NIST thread gage specifications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production inspection environments\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for straightforward No Go inspection workflow\u003c\/li\u003e\n  \u003cli\u003eFits Size 0 handle (handle not included, sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 0-80 unified internal threads, 2B tolerance class.

Before use, ensure the gage and the threaded workpiece are clean and free of chips, cutting fluid, or debris that could affect measurement accuracy. The No Go gage member should not pass through a conforming thread; if it does, the threaded feature is out of tolerance and should be rejected. Store the gage in its protective case when not in use to prevent damage to the thread form.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0-80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Size\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 34-194-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722213523762,"sku":"34-194-1","price":85.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fb04de0ce0e65c52b3e940ddb76f210.jpg?v=1788587515","url":"https:\/\/voomisupply.com\/products\/spi-34-194-1-plug-thread-gage-0-80-2b-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
