Classified as a No Go gage to the Class 2A tolerance standard, it checks 5\/8-11 UNC threads for out-of-tolerance conditions. When a properly produced thread refuses entry of the No Go gage, the part passes. Machined from tool steel, this gage delivers the hardness and dimensional stability required for repeatable inspection work in a shop or receiving environment. NIST-traceable standards govern its calibration and manufacture.\u003c\/p\u003e\u003cp\u003eThis gage is used in manufacturing, machine shops, and quality control environments where 5\/8-11 UNC external threads must be inspected for conformance to Class 2A fit requirements. It is a standard tool for incoming inspection, in-process quality checks, and final inspection of fasteners, fittings, and machined components with 5\/8-11 UNC threads. Machinists, quality technicians, and metrology professionals use this gage as part of a go\/no-go inspection pair or as a standalone no-go check.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo Go classification checks that external threads do not exceed maximum material condition for Class 2A fit\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC thread form for standard unified coarse thread inspection\u003c\/li\u003e\n\u003cli\u003eSingle ring design for straightforward, dedicated no-go inspection\u003c\/li\u003e\n\u003cli\u003eTool steel construction provides hardness and dimensional stability for long service life\u003c\/li\u003e\n\u003cli\u003eManufactured to NIST-traceable standards for reliable, documented accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of external 5\/8-11 UNC Class 2A threaded parts, including fasteners, fittings, and machined components.

Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage onto a thread under inspection — No Go gages must not pass, and applying torque to force entry will damage the gage and invalidate the inspection result. Periodic recalibration against NIST-traceable masters is required to maintain measurement integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: No Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Configuration\u003c\/strong\u003e: Single Ring\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 361147030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51750616662322,"sku":"361147030","price":200.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_608d8b91-77a9-4cf2-97b4-543a8955180b.jpg?v=1788917424","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361147030-threaded-ring-gage-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
