It checks that a 3\/8-24 UNF threaded hole meets the minimum material condition for proper fit. Classified to the 6H tolerance standard under ANSI, this gage provides a pass\/fail check when thread accuracy is critical to assembly integrity. It is used by machinists, quality control inspectors, and tool-room technicians in manufacturing, fabrication, and precision assembly environments. A Size 2 handle is required for use but is not included with this gage.\u003c\/p\u003e\n\u003cp\u003eThis plug thread gage is suited for inspection of 3\/8-24 UNF internal threads in production and quality assurance settings. Typical applications include verifying threaded bores in machined components, fastener assemblies, and precision mechanical parts where thread class conformance must be documented. The Go member confirms that a threaded hole will accept a mating fastener within tolerance. NIST traceability certification is included, making this gage appropriate for use in calibration-documented inspection programs and ISO-compliant quality systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo member only — confirms minimum material condition on 3\/8-24 UNF internal threads\u003c\/li\u003e\n  \u003cli\u003e6H classification per ANSI standards for close-tolerance thread inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production inspection use\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for calibration-documented workflows\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; accepts a Size 2 handle (handle sold separately)\u003c\/li\u003e\n  \u003cli\u003eComplies with ANSI and NIST standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 3\/8-24 UNF internal threaded features classified to the 6H tolerance standard.

Secure the gage in a compatible Size 2 handle before use. Keep the gage clean and lightly oiled when stored to prevent corrosion and protect calibrated surfaces. Do not force the Go member through a threaded hole — hand-tight engagement under light torque is the correct method.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single 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: 2 (not included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST included\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: 34-271-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720551858482,"sku":"34-271-7","price":78.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff03c4b2dd8caf218548b537879069e6.jpg?v=1788565983","url":"https:\/\/voomisupply.com\/products\/spi-34-271-7-plug-thread-gage-3-8-24-6h-single-end-go","provider":"Voomi Supply","version":"1.0","type":"link"}
