One end serves as the Go member to confirm minimum material condition, while the No Go end checks maximum material condition, together confirming conformance to Class 3B tolerance limits. The gage ships with a handle included and comes with NIST traceability certification, making it ready for immediate use in a calibrated quality-control environment. The steel construction provides durability through repeated inspection cycles on the shop floor or in a metrology lab.\u003c\/p\u003e\n\u003cp\u003eThis gage is used wherever precision internal thread verification is required on 5\/16-24 UNF tapped holes. Typical applications include incoming inspection, in-process quality checks on machined components, and final acceptance testing in manufacturing, aerospace, automotive, and general mechanical assembly operations. The double-end design consolidates both Go and No Go functions into a single tool, reducing the number of gages a technician needs to manage at the inspection station.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design combines Go and No Go members in one tool\u003c\/li\u003e\n  \u003cli\u003eVerifies 5\/16-24 UNF internal threads to Class 3B tolerance\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for calibration records\u003c\/li\u003e\n  \u003cli\u003eHandle included — ready to use out of the package\u003c\/li\u003e\n  \u003cli\u003eSteel construction for long service life under repeated use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 5\/16-24 UNF internally threaded components requiring Class 3B thread tolerance verification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread plug gages are used by quality technicians and machinists — no power tools or utilities need to be shut off before use. Apply light hand pressure when threading the Go or No Go end into the part; never force the gage with a wrench or power driver, as this can damage both the gage and the part threads. Store the gage in its protective case when not in use and return it to calibration on the interval required by your quality management system 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\/16-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Classification\u003c\/strong\u003e: 3B\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: 1\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: 34-384-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689931964722,"sku":"34-384-8","price":158.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b369b64f9850f520e0709ecfe53d2908.jpg?v=1788265357","url":"https:\/\/voomisupply.com\/products\/spi-34-384-8-plug-thread-gage-5-16-24-3b-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
