One end carries the Go member and the other carries the No Go member, allowing a technician to verify both the minimum and maximum thread tolerance limits in a single tool. The gage ships with a size 3 handle included, so no separate handle purchase is required before use. A NIST-traceable calibration certificate is included, supporting quality documentation requirements in production and inspection environments. Machinists, quality control inspectors, and toolroom technicians use this gage to accept or reject threaded holes and nuts during incoming inspection, in-process checks, or final verification.\u003c\/p\u003e\n\u003cp\u003eThe 34-411-9 is suited for production floor and inspection room use wherever 5\/8-11 internally threaded parts must be verified against ASME or ANSI thread standards. Typical applications include fabrication shops, machine shops, and assembly operations that require documented thread inspection with traceable tooling. The double-end design keeps both Go and No Go members on one gage body, reducing the number of tools a technician needs to manage during an inspection run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end configuration with Go and No Go members on a single gage\u003c\/li\u003e\n  \u003cli\u003eInspects 5\/8-11 UN internal threads to 2B tolerance class\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable calibration certificate included for quality documentation\u003c\/li\u003e\n  \u003cli\u003eSize 3 handle included — no separate handle purchase required\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 5\/8-11 UN internally threaded components classified to the 2B tolerance class.

Store the gage in its case when not in use to protect the thread members from damage and contamination. Do not force the Go member through a thread; if it does not pass with light hand pressure, the thread is out of tolerance. Recalibrate or replace the gage per your facility calibration interval schedule to maintain NIST traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Class\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go \/ No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Standard\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: 34-411-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695314010418,"sku":"34-411-9","price":226.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/412d403a32991ada9808fd50ce872a96.jpg?v=1788333807","url":"https:\/\/voomisupply.com\/products\/spi-34-411-9-plug-thread-gage-5-8-11-2b-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
