It is configured as a No Go member, meaning it verifies that a threaded hole has not been cut oversized or out of tolerance. The gage body is machined from steel for dimensional stability and wear resistance. A size 2 handle is required for use but is not included with this gage. Traceability documentation conforming to NIST standards is included, supporting quality-control and calibration recordkeeping requirements in production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in machine shops, manufacturing facilities, and field inspection settings where 1\/2-20 UNF threaded components must meet ANSI thread tolerance specifications. It is suited for incoming inspection, in-process quality checks, and final verification of tapped holes in metal parts. The single-end No Go design is typically paired with a separate Go gage to complete a full thread acceptance check per standard gaging practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go plug member for 1\/2-20 UNF internal thread inspection\u003c\/li\u003e\n  \u003cli\u003e6H tolerance class per ANSI thread standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for calibration recordkeeping\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and NIST standards\u003c\/li\u003e\n  \u003cli\u003eSize 2 handle interface — handle sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with a standard size 2 gage handle (not included) and intended to inspect 1\/2-20 UNF internal threads to 6H classification per ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread gages are installed and used by quality-control technicians and machinists — no power tools or shutoff procedures are required. Handle should be properly seated before use to ensure accurate and repeatable readings. Do not force the No Go gage into a thread; resistance at entry indicates the thread is within acceptable tolerance. Store the gage in a protective case away from contaminants to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\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: 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: 2 (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 included\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: 34-290-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720881242418,"sku":"34-290-7","price":86.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcc23d8054032c26e7fbe248daab3995.jpg?v=1788570422","url":"https:\/\/voomisupply.com\/products\/spi-34-290-7-plug-thread-gage-1-2-20-6h-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
