Machined from steel, this gage is used to confirm that a tapped hole falls within the acceptable maximum material condition limit, ensuring mating parts will assemble correctly. It ships without a handle — a Size 0 handle is required for use and must be ordered separately. Calibration traceability is provided to NIST standards, making it suitable for quality-controlled production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in precision machining, manufacturing, and assembly inspection applications where 3-48 internal threads must be verified before parts move to the next stage. It is appropriate for incoming inspection, in-process quality control, and final acceptance checks. The 6H classification aligns with standard commercial and industrial thread tolerances. Machinists, quality technicians, and tool-and-die professionals are the primary users in both job-shop and production-floor settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo-type gage checks that 3-48 internal threads meet the minimum material condition for proper mating\u003c\/li\u003e\n  \u003cli\u003e6H tolerance class conforms to ANSI unified thread standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable calibration certificate included for documentation and audit requirements\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; accepts a Size 0 handle (handle not included)\u003c\/li\u003e\n  \u003cli\u003eComplies with ANSI and NIST standards for thread gage inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Size 0 plug thread gage handles sold separately. Suitable for inspecting 3-48 unified inch internal threads to the 6H tolerance class per ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage must be mounted in a compatible Size 0 handle before use — do not attempt to use the gage member without a properly fitted handle. Apply light, consistent hand pressure when threading the gage into the part; forcing the gage can damage both the gage and the workpiece threads. Store the gage in a clean, dry environment and inspect it periodically for wear, as a worn Go gage may pass non-conforming parts. Calibration should be verified at intervals consistent with your facility's quality management system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\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: 0 (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  \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: 34-208-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690782654770,"sku":"34-208-9","price":100.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae4fc6678c29ddb9e289f18a91ae538f.jpg?v=1788275555","url":"https:\/\/voomisupply.com\/products\/spi-34-208-9-plug-thread-gage-3-48-6h-single-end-go","provider":"Voomi Supply","version":"1.0","type":"link"}
