One end carries the Go member to confirm minimum material condition and full thread engagement; the opposite end carries the No Go member to detect oversize or out-of-tolerance conditions. A handle is included, making the gage ready for immediate bench use. Traceability certification to ANSI standards referenced to NIST is provided with the gage. This tool is used by machinists, quality inspectors, and precision metrology technicians in manufacturing and production environments.\u003c\/p\u003e\u003cp\u003eThis gage is suited for incoming inspection, in-process verification, and final inspection of tapped holes and internally threaded components machined to M33x2 metric coarse thread specifications. The 6H classification reflects the standard tolerance class for general-purpose metric internal threads, making this gage applicable across a wide range of production machining, fabrication, and assembly operations where controlled thread fit is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design combines Go and No Go members in a single tool for efficient thread verification\u003c\/li\u003e\n\u003cli\u003eM33x2 thread specification with 6H tolerance class for general-purpose metric internal threads\u003c\/li\u003e\n\u003cli\u003eHandle included — no separate handle purchase required\u003c\/li\u003e\n\u003cli\u003eANSI traceability certification referenced to NIST standards included\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 6.5 inches length, 1.3 inches width, 1.3 inches height\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of internally threaded components machined to M33x2 metric thread form at 6H tolerance class.

Ensure threaded components are clean and free of chips or coolant before gaging to avoid false readings or gage wear. Apply light, consistent hand pressure when inserting the Go and No Go members; never force or torque the gage into a threaded hole. 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: M33x2\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 Plug Thread Gage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo \/ No Go\u003c\/strong\u003e: Go and No Go\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, referenced to NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.11 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: 37-211-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711594037554,"sku":"37-211-0","price":670.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1fdaf039a54e1844c9f9749abbc530c.jpg?v=1788477354","url":"https:\/\/voomisupply.com\/products\/spi-37-211-0-plug-thread-gage-m33x2-6h-go-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
