Built to a 6H tolerance class for 3\/4-20 thread forms, this gage checks that a threaded bore will accept a mating fastener at the low limit of the tolerance range. The gage body is machined from steel for dimensional stability and wear resistance. It is designed for use with a Size 3 handle, which is sold separately. Machinists, quality technicians, and manufacturing inspectors use Go plug gages as a standard go\/no-go verification step during production and incoming inspection.\u003c\/p\u003e\u003cp\u003eThis gage is appropriate for inspecting 3\/4-20 internally threaded components in precision manufacturing, aerospace, automotive, and general industrial applications. The single-end Go configuration is used when a matching No-Go gage is already on hand or when only minimum-limit verification is required. Traceability documentation to NIST standards is included with the gage, supporting quality management system requirements where documented calibration traceability is mandatory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo configuration checks that threaded bores meet minimum material condition for 3\/4-20 thread\u003c\/li\u003e\n\u003cli\u003e6H tolerance class per ANSI standards for precise thread verification\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability and dimensional stability under repeated use\u003c\/li\u003e\n\u003cli\u003eNIST traceability certification included for QMS and calibration record compliance\u003c\/li\u003e\n\u003cli\u003eSingle-end design for use alongside a separately sourced No-Go gage\u003c\/li\u003e\n\u003cli\u003eAccepts Size 3 handle (handle not included)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of internal 3\/4-20 threaded bores.

Do not force the gage into a bore; the Go member should pass under hand pressure only. Store the gage in its protective case when not in use to prevent damage to the thread form. Periodic recalibration is recommended to maintain traceable accuracy, especially in high-volume inspection environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 6H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Size\u003c\/strong\u003e: Size 3 (not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 34-319-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697523523890,"sku":"34-319-4","price":166.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22d8ee0c2176c2f96b33f404ed21ef15.jpg?v=1788352466","url":"https:\/\/voomisupply.com\/products\/spi-34-319-4-plug-thread-gage-3-4-20-6h-single-end-go","provider":"Voomi Supply","version":"1.0","type":"link"}
