Manufactured from tool steel, this single-ring gage is designed for 7\/16-20 UNF thread and is classified to Class 3A tolerance — the tightest standard fit class for inch unified external threads. Machinists, quality control technicians, and tool crib personnel use this gage during incoming inspection, in-process gauging, and final acceptance to confirm that a threaded part will assemble correctly with its mating component.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for production and inspection environments where 7\/16-20 UNF Class 3A external threads must be verified against NIST-traceable standards. Class 3A threads are common in aerospace, automotive, and precision mechanical assemblies where close tolerances and reliable fit are required. The Go ring gage is threaded onto the work piece; a conforming part passes fully through. It is used alongside a No-Go ring gage to bracket the full tolerance range, though this listing covers the Go member only.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo-class member for verifying maximum material condition on 7\/16-20 UNF external threads\u003c\/li\u003e\n  \u003cli\u003eClass 3A tolerance classification for high-precision thread inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability and wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003eSingle-ring configuration for straightforward pass\/fail gauging workflow\u003c\/li\u003e\n  \u003cli\u003eManufactured to NIST-referenced standards for traceability and consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of externally threaded parts with a 7\/16-20 UNF Class 3A thread form.

Handle the gage with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store the gage in its protective case when not in use and recalibrate periodically per your facility quality program to maintain traceability. Never force the gage onto a work piece; smooth, finger-tight engagement is the correct technique for Go-class inspection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Configuration\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST\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: VERMONT GAGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 361137520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51730157928754,"sku":"361137520","price":165.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_02442880-6c9f-4d3d-88c3-d5952d84b03f.jpg?v=1788712729","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361137520-threaded-ring-gage-7-16-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
