One end is the Go member and the opposite end is the No Go member, allowing a technician to confirm both the minimum and maximum thread limits in a single tool. The handle is included. Traceability certification meets ANSI standards with NIST traceability, making this gage suitable for quality-control environments where documented calibration records are required. Machinists, tooling engineers, and quality inspectors use this gage on the shop floor or in inspection departments to accept or reject threaded bores before assembly.\u003c\/p\u003e\u003cp\u003eThis gage is appropriate for production inspection of large-diameter internally threaded components such as flanges, housings, and structural weldments that call out M36x4 threads at the 6H fit class. The double-end configuration speeds inspection by eliminating the need to handle two separate gages. It is well suited for industries including heavy equipment manufacturing, oil and gas, structural fabrication, and aerospace where metric thread conformance must be verified against international standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo and No Go members on a single double-end gage for complete 6H thread verification\u003c\/li\u003e\n\u003cli\u003eThread size M36x4 for large-diameter metric internal thread inspection\u003c\/li\u003e\n\u003cli\u003e6H tolerance class per standard metric thread fits\u003c\/li\u003e\n\u003cli\u003eANSI traceability certification with NIST-traceable calibration included\u003c\/li\u003e\n\u003cli\u003eHandle included — ready to use out of the box\u003c\/li\u003e\n\u003cli\u003eCompact overall dimensions support bench or floor use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of M36x4 internal threads classified to the 6H tolerance class.

Ensure the workpiece is secure and free of chips or coolant before gaging. Gages should be stored in their case and periodically re-calibrated according to your facility quality plan to maintain NIST-traceable accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M36x4\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\u003eHeight\u003c\/strong\u003e: 6.75 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: 0.882 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\u003c\/strong\u003e: NIST\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: 37-214-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51716003070258,"sku":"37-214-4","price":947.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afa3702087a4e01b25f3fc2b8142f766.jpg?v=1788520865","url":"https:\/\/voomisupply.com\/products\/spi-37-214-4-plug-thread-gage-m36x4-6h-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
