Go gages confirm that a threaded hole meets the minimum material condition, allowing a properly formed mating fastener to pass through without force. This tool is a standard instrument used by machinists, quality technicians, and precision metrology professionals during in-process and final inspection of tapped holes. The 34-325-1 ships without a handle; a size 4 handle is required and must be sourced separately before use. Traceability documentation to NIST is included.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in machine shops, manufacturing facilities, and inspection departments wherever 7\/8-14 unified fine threads must be verified against ANSI and NIST standards. Single-end configuration makes it straightforward to deploy in high-volume production inspection or maintenance environments where Go verification is the primary check required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVerifies 7\/8-14 internal threads to 6H tolerance class per ANSI standards\u003c\/li\u003e\n  \u003cli\u003eGo configuration confirms minimum material condition acceptance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production inspection environments\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for quality and calibration records\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for dedicated Go verification\u003c\/li\u003e\n  \u003cli\u003eRequires size 4 handle, sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with a size 4 plug gage handle (not included) to inspect 7\/8-14 unified fine internal threads conforming to 6H class tolerances per ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread gages are installed by qualified machinists or metrology technicians using a compatible size 4 handle. Never force the Go gage into a tapped hole; if resistance is met, the hole should be re-inspected rather than forcing the gage through. Store gages in protective cases when not in use to prevent damage to thread form surfaces. Follow ANSI and NIST gage calibration intervals to maintain measurement traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\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 Required\u003c\/strong\u003e: 4 (not included)\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 included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 34-325-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711760007474,"sku":"34-325-1","price":123.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310a928a01cdc9ac243c7eac051760d0.jpg?v=1788479298","url":"https:\/\/voomisupply.com\/products\/spi-34-325-1-plug-thread-gage-7-8-14-6h-single-end-go","provider":"Voomi Supply","version":"1.0","type":"link"}
