One end carries the Go member and the opposite end carries the No Go member, allowing technicians to verify both the minimum and maximum thread tolerance limits in a single tool. A handle is included. At 0.11 pounds and measuring 2.42 inches in length with a 0.31-inch diameter profile, this is a compact, precision inspection instrument suited for quality control work on small-diameter threaded fasteners and components. Traceability certification to ANSI standards with NIST traceability is included with the gage.\u003c\/p\u003e\u003cp\u003eThis gage is used in manufacturing, machining, and assembly environments where M1.6x0.35 internal threads must be verified for conformance before parts advance to the next production stage. It is appropriate for inspection of tapped holes in small precision components such as instrument housings, electronics hardware, and miniature mechanical assemblies. The 6H tolerance class corresponds to a medium-fit internal thread, the most common classification for general-purpose metric fastener applications. Quality technicians, machinists, and metrologists are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design: Go member on one end, No Go member on the other for single-tool tolerance verification\u003c\/li\u003e\n\u003cli\u003eM1.6x0.35 thread size with 6H tolerance class for medium-fit internal thread inspection\u003c\/li\u003e\n\u003cli\u003eANSI traceability certification with NIST reference included\u003c\/li\u003e\n\u003cli\u003eHandle included — no separate purchase required\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 2.42 inches length and 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of M1.6x0.35 internal threads classified to 6H tolerance per applicable ANSI and ISO metric thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug thread gages are used by quality control technicians and machinists and require no installation in the traditional sense. Before gauging, ensure the threaded hole is clean and free of chips, cutting fluid residue, or debris that could give a false reading. Apply light, consistent hand pressure when inserting the Go and No Go members — never force the gage. Store the gage in its case when not in use to protect the precision ground threads from damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M1.6x0.35\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: Double End Go No Go Plug Thread Gage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.42 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Profile\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Reference\u003c\/strong\u003e: NIST\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: 37-178-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51718345851186,"sku":"37-178-1","price":398.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8aacaa2d7eb7823373f2b78db1eea6eb.jpg?v=1788552322","url":"https:\/\/voomisupply.com\/products\/spi-37-178-1-plug-thread-gage-m1-6x0-35-6h-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
