It is a single-ring gage manufactured from tool steel and classified to Class 3A tolerance standards, making it suitable for precision thread inspection in production and quality control environments. The Go ring confirms that a threaded part falls within the acceptable maximum material condition, allowing passage when the thread form, pitch diameter, and lead are within tolerance. Machinists, quality inspectors, and tool room technicians use this gage in manufacturing, maintenance, and assembly operations where UNC thread conformance must be documented.\u003c\/p\u003e\n\u003cp\u003eThis gage is applied wherever 3\/8-16 UNC external threads require dimensional verification against Class 3A tolerance limits. Class 3A represents a close-tolerance fit commonly specified for high-strength fastener applications, aerospace assemblies, and precision mechanical components. The gage is used at incoming inspection stations, on production lines, and during tool and fixture verification. It is suited for both job shop and high-volume manufacturing environments where consistent thread quality is a requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo-type ring gage confirms external thread acceptability at maximum material condition\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for standard unified coarse pitch inspection\u003c\/li\u003e\n  \u003cli\u003eClass 3A classification for close-tolerance thread verification\u003c\/li\u003e\n  \u003cli\u003eSingle-ring configuration for dedicated Go-function gauging\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eManufactured to NIST-traceable standards for calibration compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of external 3\/8-16 UNC Class 3A threaded parts including bolts, screws, studs, and other male-threaded components conforming to the Unified National Coarse thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreaded ring gages are handled and applied by quality control technicians and machinists trained in thread gauging practice. Store the gage in its case when not in use and keep it free of chips, coolant, and debris before and after each use. Gages should be periodically checked against a certified setting plug to confirm calibration status has not drifted due to wear. Never force the gage onto a threaded part; if resistance is encountered beyond normal hand torque, inspect the part for burrs or gross dimensional nonconformance before proceeding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNC (Unified National Coarse)\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 Function\u003c\/strong\u003e: 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\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: 361133020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51735632281906,"sku":"361133020","price":166.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_dd82de28-da34-4975-9326-88864a68c750.jpg?v=1788773378","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361133020-threaded-ring-gage-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
