With a measurement diameter of 0.02 inches and a tolerance of 0.0002 inches, this gage provides precise go\/no-go inspection capability for tight-tolerance machined components. Constructed from steel for durability and dimensional stability, it is a standard tool in quality control environments, machine shops, and precision manufacturing facilities. Metrologists, machinists, and quality technicians use plug gages like this one to confirm that drilled, reamed, or bored features meet specification without relying on indirect measurement tools.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for inspection of small-bore features in precision machined parts across industries such as aerospace, automotive, and general manufacturing. Class ZZ Plus gages are typically used in production-level inspection where consistent, repeatable go\/no-go verification is required. The 0.02-inch diameter makes this gage appropriate for very fine bores that cannot be checked reliably with standard handheld instruments. It is commonly used at incoming inspection stations, on the shop floor, or in quality labs where rapid, accurate hole verification is part of standard workflow.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement diameter of 0.02 inches for very small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for production-level accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eGo\/no-go design enables fast, repeatable pass-fail inspection\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suited for tight-access bore locations\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 go\/no-go inspection of 0.02-inch diameter bores in precision machined components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists and do not require installation in the traditional sense. Before use, clean the gage and the bore being inspected to remove chips, coolant, or debris that could affect measurement accuracy. Handle the gage with care to avoid dropping or scoring the gage surface, as damage to a precision ground surface will affect dimensional accuracy. Store in a protective case away from temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.02 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\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: 29-020-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691512856882,"sku":"29-020-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f902723b5eddf7ab9951fa0aed917d07.jpg?v=1788286297","url":"https:\/\/voomisupply.com\/products\/spi-29-020-5-class-zz-plus-plug-gage-0-02-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
