One end carries the Go member and the opposite end carries the No Go member, allowing a technician to verify both the minimum and maximum thread limits in a single tool. The gage ships with a handle included and comes with ANSI traceability certification traceable to NIST standards. It is the standard tool used in machine shops, manufacturing facilities, and quality-control environments where metric thread conformance must be documented.\u003c\/p\u003e\u003cp\u003eThis gage is suited for verifying M18x1.5 threads in precision machined components, hydraulic fittings, automotive parts, and any application where 6H class thread tolerance must be confirmed before assembly. The double-end configuration speeds inspection workflow by eliminating the need to swap gage members between Go and No Go checks. Quality inspectors, machinists, and manufacturing engineers are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design with Go and No Go members on a single tool\u003c\/li\u003e\n\u003cli\u003eM18x1.5 thread size with 6H tolerance class\u003c\/li\u003e\n\u003cli\u003eHandle included for comfortable single-hand operation\u003c\/li\u003e\n\u003cli\u003eANSI traceability certification included, standards traceable to NIST\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.22 pounds for easy bench and floor use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of M18x1.5 internal threads conforming to 6H tolerance class per applicable ANSI and metric thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread gages are inspection instruments, not installation components. Always store the gage in its protective case when not in use to prevent damage to the thread members. Do not force the Go end through a thread — drag or resistance indicates an out-of-tolerance condition. Periodic recalibration against NIST-traceable standards is recommended 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: M18x1.5\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 \/ No Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\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\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\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: 37-200-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696348365106,"sku":"37-200-3","price":190.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce46db682c22b56756a4beeebfeaa55c.jpg?v=1788341749","url":"https:\/\/voomisupply.com\/products\/spi-37-200-3-plug-thread-gage-m18x1-5-6h-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
