One end carries the Go member and the opposite end carries the No Go member, allowing a technician to confirm both minimum material condition and maximum material condition in a single tool. The gage ships with a handle included. A NIST-traceable calibration certificate is included, making this gage suitable for documented quality control processes on the shop floor or in a metrology lab. The tool weighs 1 pound and is constructed of steel for dimensional stability under repeated use.\u003c\/p\u003e\n\u003cp\u003eThis gage is intended for use in precision machining, manufacturing inspection, and quality assurance environments where threaded fastener holes must be verified against ANSI or ASME thread standards. The 3-48 designation indicates a Number 3 nominal diameter with 48 threads per inch, a fine-pitch unified thread commonly found in small instrument components, electronics hardware, and precision mechanical assemblies. Licensed metrology technicians, quality inspectors, and precision machinists are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design with Go and No Go members on a single gage body for efficient pass-fail inspection\u003c\/li\u003e\n  \u003cli\u003e3-48 thread size with 2B tolerance class conformance\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable traceability certification included for documented quality systems\u003c\/li\u003e\n  \u003cli\u003eHandle included — no separate handle purchase required\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread inspection gage for internal 3-48 UNC\/UNF threaded features inspected to 2B class tolerance requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread plug gages are hand-operated inspection tools requiring no power source or permanent installation. The Go member should pass fully through a conforming threaded hole under finger pressure only — do not force the gage. The No Go member should not enter more than two turns of a conforming threaded hole. Follow your facility gauge management program and applicable ASME B1.2 or ASME B47.1 standards for gage calibration intervals and handling procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance 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 Included\u003c\/strong\u003e: Yes\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  \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: 34-347-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696221946162,"sku":"34-347-5","price":211.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e6068da0023bbdecd2981ae56bed084.jpg?v=1788340518","url":"https:\/\/voomisupply.com\/products\/spi-34-347-5-plug-thread-gage-3-48-2b-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
