Classified to the 6H tolerance class per ANSI and NIST standards, this gage confirms that a tapped hole will accept a mating fastener without interference. It is designed for use with a Size 2 handle, sold separately. Machinists, quality technicians, and inspection personnel use this tool on the shop floor or in receiving inspection to validate threaded holes during production or incoming part verification.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for precision inspection of 7\/16-28 Unified National Fine (UNF) internal threads in manufacturing, aerospace, automotive, and general mechanical assembly environments. The Go member checks that the thread form, pitch diameter, and lead fall within the acceptable lower limit, ensuring proper fit with a corresponding external thread. It is commonly used alongside a No-Go gage to complete a full pass\/fail thread inspection routine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo member verifies minimum material condition on 7\/16-28 internal threads\u003c\/li\u003e\n  \u003cli\u003e6H tolerance classification per ANSI and NIST standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production inspection environments\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for straightforward Go-only inspection tasks\u003c\/li\u003e\n  \u003cli\u003eCompatible with Size 2 thread gage handles (handle not included)\u003c\/li\u003e\n  \u003cli\u003eTraceability certification to NIST standards included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Size 2 plug thread gage handles.

Ensure the threaded workpiece is clean and free of chips, burrs, or coolant before gaging to avoid false readings or gage wear. Store the gage in its protective case when not in use to preserve calibration and surface finish. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Classification\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  \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: 34-283-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693144998194,"sku":"34-283-2","price":153.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/547a389ac8761796ed460ed13530cf17.jpg?v=1788307931","url":"https:\/\/voomisupply.com\/products\/spi-34-283-2-plug-thread-gage-7-16-28-6h-single-end-go","provider":"Voomi Supply","version":"1.0","type":"link"}
