One end is the Go member and the opposite end is the No Go member, allowing a technician to verify both minimum and maximum thread tolerance in a single tool. A handle is included. The gage is traceable to NIST standards and ships with an ANSI traceability certification, making it suitable for quality-control environments where documentation is required. Machinists, quality inspectors, and tool-room technicians use this type of gage to confirm threaded holes are within specification before parts move to assembly.\u003c\/p\u003e\n\u003cp\u003eThis gage is used wherever M4x0.7 threaded holes must be verified to the 6H tolerance class. Typical applications include incoming inspection of machined components, in-process thread verification on CNC or manually tapped parts, and final inspection in manufacturing environments. The double-end configuration reduces the number of individual gages needed when checking both Go and No Go conditions on the same feature.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo and No Go members on a single double-end gage body\u003c\/li\u003e\n  \u003cli\u003eConforms to M4x0.7 thread size at 6H tolerance class\u003c\/li\u003e\n  \u003cli\u003eIncludes handle for comfortable single-hand use\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable with ANSI traceability certification included\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.044 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of M4x0.7 metric internal threads manufactured to the 6H tolerance class per ANSI and NIST-referenced standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread gages are inspection tools and do not require installation in the traditional sense. Handle the gage with clean, dry hands or lint-free gloves to prevent corrosion and contamination of the thread members. Apply light, consistent hand pressure when gauging — never force the Go member or apply torque tools. Store the gage in its protective case when not in use to preserve thread-form accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.7\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 Plug Thread Gage\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\u003eStandard\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 pounds\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: 37-185-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698870354226,"sku":"37-185-6","price":169.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1e5ce52e88b8aab2e93b7987223d4be.jpg?v=1788369147","url":"https:\/\/voomisupply.com\/products\/spi-37-185-6-plug-thread-gage-m4x0-7-6h-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
