It measures a nominal diameter of 0.369 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go gauging applications where tight dimensional control is required. Machined from steel, this plug gage delivers consistent performance in tool rooms, machine shops, and quality control settings. Machinists, toolmakers, and quality inspectors rely on plug gages like this one to confirm bore size compliance with engineering specifications before and during assembly.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in both job shop and production floor environments where hole diameter verification is part of the inspection process. It is well suited to checking drilled, reamed, or bored holes in metal components across general manufacturing, aerospace preparation work, and precision machining operations. At 0.369 inches, it addresses a common intermediate bore size encountered in shaft-fit and fastener-clearance applications. The compact, single-piece form allows fast, repeatable checks without complex setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.369 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches ensures high gauging accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability during repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact single-unit form factor supports fast go\/no-go inspection cycles\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for comfortable hand use during extended inspection runs\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 use with any go\/no-go gage handle or fixture that accepts 0.369-inch diameter gage members in production and quality inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, verify the gage is clean and free of burrs or debris that could affect measurement accuracy. Store in a protective case away from abrasive materials and temperature extremes to maintain dimensional integrity. Calibration intervals should follow your facility's quality management plan and applicable metrology standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.369 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (Decimal Inch)\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-369-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699709673778,"sku":"29-369-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9700a2c2f755f113041c44dcc3ce4dee.jpg?v=1788379604","url":"https:\/\/voomisupply.com\/products\/spi-29-369-6-class-zz-plus-plug-gage-0-369-in","provider":"Voomi Supply","version":"1.0","type":"link"}
