Plug gages in this class are used for go\/no-go dimensional inspection of bored, drilled, and reamed holes in machined components. The steel construction provides durability for repeated use in shop-floor and quality-control environments. Machinists, tool-and-die makers, and quality technicians use this type of gage to verify conformance to tight dimensional tolerances without relying on calipers or micrometers alone.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for production inspection and incoming quality control in manufacturing and fabrication settings. It is used wherever a 0.525-inch nominal hole diameter must be verified against a specified tolerance. Typical applications include inspection of machined housings, fixtures, and precision mechanical assemblies. The Class ZZ Plus designation indicates a higher accuracy tolerance class appropriate for general-purpose production gaging where reliable go\/no-go verification is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.525 inches for direct hole-size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for accurate go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging for individual replacement or kit supplementation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard go\/no-go plug gage for use with any handle or gage holder that accepts a 0.525-inch diameter gage member, consistent with general-purpose Class ZZ plug gage applications in production inspection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control technicians — no installation in the traditional sense is required. Before use, ensure the gage and the workpiece bore are clean and free of chips, coolant, and debris to prevent false readings or damage to the gage surface. Do not force the gage member into an undersized hole, as this can damage the gage or the workpiece. Store the gage in a protective case away from other metal tools to prevent surface damage that would affect calibration accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.525 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class 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: 29-525-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689870623026,"sku":"29-525-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7c568cfabf39dc13988131c5a360741.jpg?v=1788265007","url":"https:\/\/voomisupply.com\/products\/spi-29-525-3-class-zz-plus-plug-gage-0-525-in","provider":"Voomi Supply","version":"1.0","type":"link"}
