It includes both a Go and No Go member, allowing technicians to confirm that a tapped hole falls within the acceptable tolerance range in a single tool set. The gage is machined from tool steel for dimensional stability and wear resistance under repeated use. A 2-inch taperlock handle is included. This type of gage is standard equipment for machinists, quality inspectors, and precision manufacturing tradespeople working to UNEF thread standards.\u003c\/p\u003e\u003cp\u003eThis gage is suited for inspection of 7\/16-28 UNEF internal threads in production, maintenance, and quality-assurance environments. It is appropriate for both shop-floor use and receiving inspection where Class 2A thread conformance must be verified. The truncated form reduces contact area on the thread flanks, which can extend gage service life in high-volume inspection applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo and No Go members included for complete Class 2A tolerance verification\u003c\/li\u003e\n\u003cli\u003eThread specification: 7\/16-28 UNEF\u003c\/li\u003e\n\u003cli\u003eTruncated taperlock design reduces flank wear in repetitive use\u003c\/li\u003e\n\u003cli\u003eTool steel construction for dimensional stability and durability\u003c\/li\u003e\n\u003cli\u003e2-inch taperlock handle included\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 5.75 inches for easy handling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of 7\/16-28 UNEF internal threads conforming to Class 2A tolerance requirements.

Before use, clean the gage and the threaded hole being inspected to remove chips, oil, and debris that could produce false readings. Do not force the No Go member into a thread — if it enters more than two turns under finger pressure, the thread is out of tolerance. Store the gage in a protective case away from impact and temperature extremes to preserve calibration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNEF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: Go and No Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Truncated Taperlock Thread Plug Gage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.553 pounds\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: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 23-174-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715284271410,"sku":"23-174-6","price":469.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f68b6da40c1a8362157c439430d49626.jpg?v=1788511570","url":"https:\/\/voomisupply.com\/products\/spi-23-174-6-thread-plug-gage-7-16-28-unef-go-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
