Machined from steel, this gage checks that a threaded hole has not been cut oversized or out of tolerance, rejecting any feature that allows the No Go member to pass. It is used at the point of manufacture or incoming inspection to verify conformance to ANSI thread standards. The gage is supplied with NIST-traceable certification, making it suitable for quality-controlled production environments. A size 4 handle is required for operation and is sold separately.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in precision machining shops, aerospace, automotive, and general manufacturing environments where 7\/8-14 UNF internal thread inspection is required. Inspectors and machinists use it at CNC machining centers, assembly lines, or incoming inspection stations to screen parts before they advance in the production process. Its single-end No Go configuration keeps it dedicated to one function, reducing the risk of operator error during high-volume inspection runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go member rejects oversized or out-of-tolerance 7\/8-14 internal threads\u003c\/li\u003e\n  \u003cli\u003e6H tolerance class conforms to ANSI thread gage standards\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable certification included for quality and audit compliance\u003c\/li\u003e\n  \u003cli\u003eSingle-end design dedicated to No Go inspection function\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production inspection environments\u003c\/li\u003e\n  \u003cli\u003eAccepts size 4 handle (handle not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 7\/8-14 UNF internal threads to 6H class tolerance.

Before use, clean the threaded bore and gage member to remove chips, coolant, and debris that could produce false readings. Do not force the No Go member into a thread — hand pressure only. Store the gage in its case when not in use to protect the precision ground surfaces from damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\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: 4 (not included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34-326-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51702667247922,"sku":"34-326-9","price":124.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7036ffabda5439174687576d1f137a58.jpg?v=1788412642","url":"https:\/\/voomisupply.com\/products\/spi-34-326-9-plug-thread-gage-7-8-14-6h-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
