Classified to 2B tolerance, it checks that a tapped hole accepts a mating fastener within the accepted limits for standard fit. Manufactured from steel for dimensional stability under shop conditions, this gage is an essential inspection tool for machinists, toolroom technicians, and quality control personnel working with miniature fastener threads. NIST traceability certification is included, supporting documented inspection processes and calibration records. A size 000 handle is required for use but is sold separately.\u003c\/p\u003e\u003cp\u003eThe 34-193-3 is suited for incoming inspection, in-process verification, and final inspection of 0-80 threaded features in precision components. Typical applications include aerospace hardware, optical instrument assemblies, electronics enclosures, and any manufactured part using miniature unified threaded fasteners. The Go member confirms the hole will accept a conforming mating thread without interference.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo member checks that 0-80 2B tapped holes fall within acceptable minimum material limits\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability and dimensional stability for repeated use\u003c\/li\u003e\n\u003cli\u003eNIST traceability certification included for calibration documentation and quality compliance\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NIST standards for thread gage classification\u003c\/li\u003e\n\u003cli\u003eSingle-end design for dedicated Go inspection — pair with a No-Go gage for full limit checking\u003c\/li\u003e\n\u003cli\u003eCompatible with size 000 gage handles (handle not included)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with size 000 plug thread gage handles to inspect 0-80 UNF internal threads classified to 2B tolerance.

Keep the gage clean and lightly oiled when stored to prevent corrosion and protect thread form accuracy. Do not force the Go member into a hole that resists entry, as this can damage the gage or the workpiece. Follow your facility calibration schedule and reference the included NIST traceability certificate 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: 0-80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Classification\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo\/No-Go\u003c\/strong\u003e: Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\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: 000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 34-193-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698120294706,"sku":"34-193-3","price":84.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7ae28285648473a667b9e6cee3a0885.jpg?v=1788357997","url":"https:\/\/voomisupply.com\/products\/spi-34-193-3-plug-thread-gage-0-80-2b-class-go","provider":"Voomi Supply","version":"1.0","type":"link"}
