Configured as a No Go member, it verifies that an internal thread does not exceed its maximum material condition, confirming the thread is within the specified tolerance. The gage body measures 2.13 inches in height and 1.3 inches in width and length, and weighs 0.441 pounds. Traceability certification is provided to ANSI standards referenced to NIST. A handle is not included with this gage and must be sourced separately. Machinists, quality control inspectors, and precision tool specialists use this gage in production and inspection environments.\u003c\/p\u003e\u003cp\u003eThis plug thread gage is suited for inspecting M33x2 internally threaded components in manufacturing, machining, and precision fabrication settings. It is used wherever metric thread verification is required to 6H tolerance, including work on threaded bores in mechanical assemblies, hydraulic fittings, and industrial equipment. The single-end No Go configuration allows targeted go or no-go inspection without a combined handle gage setup, making it practical for dedicated inspection stations or field verification use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo Go member for M33x2 metric internal thread inspection to 6H tolerance class\u003c\/li\u003e\n\u003cli\u003eSingle-end design for dedicated No Go verification without a double-end setup\u003c\/li\u003e\n\u003cli\u003eANSI traceability certification included, referenced to NIST standards\u003c\/li\u003e\n\u003cli\u003eCompact form: 2.13 inches height, 1.3 inches width and length\u003c\/li\u003e\n\u003cli\u003eHandle not included, compatible with standard plug gage handles sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard plug gage handles compatible with the M33x2 thread size range.

Before use, clean both the gage and the threaded bore to remove chips, cutting fluid, and debris. Apply light gage oil when appropriate to reduce wear during inspection. Thread gaging should be performed by qualified inspection personnel following applicable shop standards and ANSI gaging practices.\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: No Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\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: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.441 pounds\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 Reference\u003c\/strong\u003e: NIST\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: 37-172-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720619983154,"sku":"37-172-4","price":285.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ecc2527acc7debfe911a9267254fec8.jpg?v=1788567037","url":"https:\/\/voomisupply.com\/products\/spi-37-172-4-plug-thread-gage-m33x2-6h-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
