Built to 4-40 UNC 2B class-of-fit specifications, this gage checks that a tapped hole does not exceed the maximum material condition for the thread class. The NoGo member features a 0.2188-inch length and a pitch of 0.0991 inch. Each gage ships marked with nominal size, threads per inch, class of fit, and pitch diameters. A certificate of accuracy is included with every unit.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in manufacturing, machining, and quality-control environments where 4-40 UNC internally threaded components must be verified to print. Typical applications include inspection of tapped holes in electronics enclosures, instrument housings, and precision assemblies requiring fine unified threads. It fits standard Taperlock-style gage handles, which are sold separately, making it compatible with common shop-floor gage setups used by machinists and QC inspectors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNoGo (Minus) member verifies that internal threads do not exceed maximum pitch-diameter tolerance for 4-40 UNC 2B fit\u003c\/li\u003e\n  \u003cli\u003eTaperlock design seats securely in compatible Taperlock gage handles\u003c\/li\u003e\n  \u003cli\u003eMarked with nominal size, threads per inch, class of fit, and pitch diameters for quick identification\u003c\/li\u003e\n  \u003cli\u003eCertificate of accuracy included for traceability and quality documentation\u003c\/li\u003e\n  \u003cli\u003eOptional custom marking available  -  up to 25 additional characters at no extra cost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Taperlock-style gage handles sized for small-diameter thread plug gages.

Insert the Taperlock shank into a compatible handle and secure it before use. The NoGo member should not pass through a conforming threaded hole; if it does, the hole is out of tolerance. Handle and store gages carefully to prevent nicking or corrosion, which can affect measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: NoGo (Minus)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Taperlock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoGo Length\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoGo Pitch\u003c\/strong\u003e: 0.0991 inches\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: VERMONT GAGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 301000000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":68086321840434,"sku":"301110020","price":90.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fa67480212d85f21905247e3e62e0c_da819cae-89e2-4180-a942-09834e56e52d.jpg?v=1793189165","url":"https:\/\/voomisupply.com\/products\/vermont-gage-301000000-thread-plug-gage-4-40-unc-2b-nogo","provider":"Voomi Supply","version":"1.0","type":"link"}
