It measures a nominal diameter of 0.38 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work where tight dimensional control is required. Constructed from steel for durability and wear resistance, this plug gage is a standard hand tool used by machinists, quality technicians, and tool-and-die professionals. Its compact size and light weight make it easy to handle during high-volume inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in shop floor and laboratory environments where bore diameter verification is part of a standard inspection process. It is well suited for checking drilled, reamed, or bored holes in metal and plastic workpieces. Typical applications include incoming inspection, in-process quality checks, and final part verification in manufacturing and fabrication settings. The Class ZZ Plus classification indicates a specific tolerance grade appropriate for general-purpose inspection work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.38 inches for precise bore inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches meets Class ZZ Plus grade requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for comfortable single-hand use\u003c\/li\u003e\n  \u003cli\u003eSuitable for go\/no-go inspection routines in production environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for general-purpose bore and hole diameter inspection at 0.38 inches nominal diameter.

Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the gage into a hole that is undersized, as this can damage the gage surface and affect calibration. Periodic recalibration against a certified reference standard is recommended to maintain measurement traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 29-380-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700964557106,"sku":"29-380-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89e3388865a2b7a2c57fa898533498b4.jpg?v=1788395949","url":"https:\/\/voomisupply.com\/products\/spi-29-380-3-class-zz-plus-plug-gage-0-38-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
