It includes both Go and No Go members mounted on a 4-inch taperlock handle, allowing a single tool setup to confirm both minimum and maximum thread acceptance limits. The gage is machined from tool steel for dimensional stability and wear resistance under repeated use. At 1.481 pounds, the assembly is easy to handle during production floor or incoming inspection work. This gage is used by quality technicians and machinists to verify threaded components before assembly.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspecting 7\/8-20 UNEF threaded parts in manufacturing, aerospace, automotive, and general machining environments where Class 2A thread tolerances must be confirmed. The truncated taperlock design allows fast member swaps on a standard taperlock handle, making it practical for high-volume inspection lines. The included 4-inch handle provides a comfortable grip and standard taper engagement for secure member retention during use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInspects 7\/8-20 UNEF threads to Class 2A tolerance with Go and No Go members\u003c\/li\u003e\n  \u003cli\u003eTruncated taperlock design for fast, secure member changes on standard handles\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for dimensional stability and extended service life\u003c\/li\u003e\n  \u003cli\u003e4-inch taperlock handle included in the set\u003c\/li\u003e\n  \u003cli\u003eSingle setup confirms both acceptance and rejection limits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard taperlock handle systems for inspecting 7\/8-20 UNEF Class 2A threaded components.

Ensure the taperlock member is fully seated and locked in the handle before use. Clean threads on the part being inspected and on the gage members before each check to prevent false readings or gage wear. Store gage members in a protective case when not in use to preserve calibration and surface condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-20\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.481 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Handle\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: 23-204-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698473992498,"sku":"23-204-1","price":603.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/124b668e8d8b5fd5df3461cfec847e3a.jpg?v=1788363430","url":"https:\/\/voomisupply.com\/products\/spi-23-204-1-truncated-taperlock-thread-plug-gage-7-8-20-unef","provider":"Voomi Supply","version":"1.0","type":"link"}
