Class ZZ is the standard tolerance class for plug gages used in inspection-room and production floor applications where consistent, repeatable measurement is required. The gage is machined from steel and held to a tolerance of 0.0002 inches, making it suitable for verifying hole acceptance criteria on machined components. Licensed machinists, quality control technicians, and toolroom professionals use this type of gage as part of routine dimensional verification.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in manufacturing, toolroom, and quality inspection environments where hole diameter conformance must be verified against a fixed tolerance. Typical applications include incoming inspection of machined parts, in-process checking on production lines, and final acceptance testing for fabricated assemblies. The 0.229-inch nominal diameter covers a specific range of drilled or reamed hole sizes common in light mechanical and precision machined components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class for standard production and inspection use\u003c\/li\u003e\n  \u003cli\u003e0.229-inch nominal measurement diameter for precise hole verification\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for consistent go\/no-go acceptance decisions\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production floor and inspection room environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suitable for individual toolroom or bench stock use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition to Class ZZ plug gage sets used in standard machining and inspection applications at 0.229-inch nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists; no power tools or utilities need to be shut down before use. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel contact surfaces. Do not force the gage into an undersized hole, as this can damage the gage or scratch the bore. Store separately from other tooling to avoid contact damage to the precision-ground surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.229 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\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  \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: 29-229-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689697083698,"sku":"29-229-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccf68be264e212bf095518ca0ebc2b31.jpg?v=1788263167","url":"https:\/\/voomisupply.com\/products\/spi-29-229-2-class-zz-plus-plug-gage-0-229-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
