One end serves as the Go member and the other as the No Go member, allowing a technician to confirm both the minimum material condition and the rejection threshold in a single tool. A handle is included. This gage is used in machine shops, manufacturing lines, and quality-control environments where threaded bore acceptance must be documented. Traceability is supported through an included ANSI certification traceable to NIST, satisfying most inspection and audit requirements.\u003c\/p\u003e\u003cp\u003eThe 37-203-7 is suited for incoming inspection, in-process verification, and final acceptance of M20x2.5 6H threaded bores. Common applications include fastener-hole inspection on structural assemblies, hydraulic manifolds, and machined housings where thread fit and engagement length are critical to joint integrity. The double-end configuration keeps both Go and No Go members on one handle, reducing tool changeover time on the inspection bench.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design combines Go and No Go members on a single handle for efficient inspection\u003c\/li\u003e\n\u003cli\u003eM20x2.5 thread form, 6H tolerance class for internal thread verification\u003c\/li\u003e\n\u003cli\u003eHandle included — no separate handle purchase required\u003c\/li\u003e\n\u003cli\u003eANSI traceability certification included, traceable to NIST standards\u003c\/li\u003e\n\u003cli\u003eCompact profile: 0.8 inches wide, 0.8 inches in depth, 3.16 inches in height\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.441 pounds for comfortable bench or floor use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for verifying internal M20x2.5 threaded bores to the 6H tolerance class per ANSI standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread gages are handled by quality-control inspectors or machinists and require no installation in the traditional sense. Always clean and deburr the threaded bore before gaging to prevent false rejects and gage wear. Do not force the No Go member into a bore; hand-torque entry only. Store the gage in its case and calibrate on a schedule consistent with your quality management system requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20x2.5\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, traceable to NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.441 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: 37-203-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711474073906,"sku":"37-203-7","price":215.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9aeec76125c8ca893dafd322edc82163.jpg?v=1788476741","url":"https:\/\/voomisupply.com\/products\/spi-37-203-7-double-end-plug-thread-gage-m20x2-5-6h","provider":"Voomi Supply","version":"1.0","type":"link"}
