It is used to verify that a threaded hole falls within the acceptable maximum material condition limits, confirming the thread will accept a mating fastener. The gage body measures 1.42 inches wide by 2.13 inches tall and weighs 2.11 pounds. Handle is not included and must be sourced separately. Traceability certification is provided to ANSI standards with NIST traceability, making it suitable for quality control environments where documented measurement accuracy is required.\u003c\/p\u003e\n\u003cp\u003eThis gage is applied in manufacturing, machining, and maintenance environments where M36x4 threaded holes must be inspected for conformance before assembly. Typical users include machinists, quality control technicians, and tool-and-die professionals working with large-diameter metric threaded components. The Go gage member confirms minimum thread form and pitch diameter acceptability. It is appropriate for both production floor inspection and incoming inspection of machined parts in industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo member checks M36x4 internal threads to 6H tolerance class\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for straightforward Go inspection workflow\u003c\/li\u003e\n  \u003cli\u003eANSI certification with NIST traceability included for documented quality assurance\u003c\/li\u003e\n  \u003cli\u003eHandle not included, compatible with standard plug gage handles sold separately\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 1.42 inches wide, 2.13 inches tall, 2.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inspection tool for M36x4 internally threaded components held to 6H tolerance class per ANSI and NIST-traceable standards.

Before use, ensure the threaded hole is clean and free of chips, coolant, or debris that could affect the gage reading. The gage should be stored in a controlled environment and periodically recalibrated in accordance with your facility quality system requirements. Do not force the gage into a non-conforming thread, as this can damage the gage member and invalidate its calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M36x4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGo or No Go\u003c\/strong\u003e: Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: No\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: 2.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.11 pounds\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: 37-175-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695073329458,"sku":"37-175-7","price":414.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4bac88b359fc2cd8f1273e382ad8d8d.jpg?v=1788331080","url":"https:\/\/voomisupply.com\/products\/spi-37-175-7-plug-thread-gage-m36x4-6h-class-go","provider":"Voomi Supply","version":"1.0","type":"link"}
