One end carries the Go member and the other carries the No Go member, allowing a technician to verify both minimum and maximum thread acceptance in a single tool. The gage is made from steel and ships with a size 0 handle included. A NIST-traceable certification is included with each unit, supporting quality documentation requirements in precision manufacturing and inspection environments. This tool is used by machinists, quality control inspectors, and toolroom technicians working with fine-pitch fastener threads.\u003c\/p\u003e\n\u003cp\u003eThe 34-337-6 is suited for incoming inspection, in-process verification, and final inspection of tapped holes and threaded components using #0-80 thread form. The 2B classification covers the standard commercial tolerance range for inch-series internal threads, making this gage applicable across general-purpose machined parts, instrument assemblies, and small mechanical components where thread fit and function must be confirmed before assembly.\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 for efficient thread inspection\u003c\/li\u003e\n  \u003cli\u003eInspects #0-80 thread size to 2B tolerance class per NIST standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSize 0 handle included — no separate handle purchase required\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable traceability certification included for quality system compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of internal #0-80 UNC threads in machined components, instrument housings, and assemblies requiring 2B class thread verification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread gages are inspection tools and do not require installation, but proper handling practice applies. Store the gage in its case when not in use to protect the go and no go members from contact damage. Clean threads and the gage members before inspection to prevent debris from causing false rejects. Calibration intervals should follow the quality system requirements of your facility; the included NIST-traceable certification supports initial traceability documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: #0-80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End (Go \/ No Go)\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: 0\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\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: 34-337-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696444768562,"sku":"34-337-6","price":187.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48021cb830a8c56c0e629c9d657498db.jpg?v=1788342743","url":"https:\/\/voomisupply.com\/products\/spi-34-337-6-plug-thread-gage-0-80-2b-double-end-go-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
