It checks both Go and No Go conditions in a single tool, confirming that a threaded feature accepts a conforming fastener and rejects an out-of-tolerance one. The gage is manufactured from steel and conforms to NIST standards, making it suitable for calibrated inspection environments. A handle is included. Licensed machinists, quality control inspectors, and precision fabricators use this type of gage as part of standard thread verification workflows in manufacturing and maintenance settings.\u003c\/p\u003e\n\u003cp\u003eThis gage is used wherever 6-40 internal threads require dimensional verification, including precision machined components, instrument enclosures, and small-fastener assemblies. The 2B classification designates a standard commercial tolerance class for inch-series unified threads, covering the majority of general-purpose internal thread applications. The double-end design places the Go member on one end and the No Go member on the other, eliminating the need for two separate gages on the same inspection station.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVerifies 6-40 internal threads to 2B tolerance class per NIST standards\u003c\/li\u003e\n  \u003cli\u003eDouble-end design with Go and No Go members on a single tool\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production inspection environments\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for calibrated measurement programs\u003c\/li\u003e\n  \u003cli\u003eHandle included — no separate handle purchase required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 6-40 unified inch-series internal threads classified to 2B tolerance, as found in general-purpose threaded components across manufacturing and assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug thread gages are used by quality control technicians and precision machinists — no power tools or utilities need to be shut down before use. Thread the Go end into the inspected hole using hand pressure only; forced insertion can damage the gage and produce false readings. Store gages in a protective case away from contaminants and other metal tooling to preserve calibration. Re-certification intervals should follow your facility's calibration management program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40\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 Standard\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: 34-361-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710288920882,"sku":"34-361-6","price":185.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8edf439280c6b30b247d2ead0eb6e8c4.jpg?v=1788465237","url":"https:\/\/voomisupply.com\/products\/spi-34-361-6-plug-thread-gage-6-40-2b-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
