It holds a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work in production and quality control environments. Constructed from steel, the gage provides the wear resistance and dimensional stability required for repetitive use on the shop floor. Licensed machinists, toolmakers, and quality technicians use Class ZZ gages for in-process inspection of drilled, reamed, or bored holes where maintaining consistent bore sizing is critical to part function.\u003c\/p\u003e\u003cp\u003eThis plug gage is used in machine shops, fabrication facilities, and manufacturing environments where bore diameter verification is part of standard quality assurance workflow. It is appropriate for inspecting ferrous and non-ferrous workpieces where a 0.575-inch nominal hole diameter must be confirmed within tight tolerance. The 0.0002-inch tolerance class positions this gage for inspection of medium-precision bores in general production work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNominal measurement diameter of 0.575 inches for direct bore verification\u003c\/li\u003e\n\u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable go\/no-go inspection\u003c\/li\u003e\n\u003cli\u003eSteel construction provides dimensional stability and wear resistance\u003c\/li\u003e\n\u003cli\u003eCompact, single-piece gage suited for hand-held shop-floor use\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.2 pounds for ease of handling during repeated checks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard plug gage for use in any go\/no-go inspection application requiring a 0.575-inch nominal bore check at Class ZZ Plus tolerance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are used by machinists and quality control technicians and require no permanent installation. Before use, ensure the workpiece bore is clean and free of chips, burrs, or coolant residue that could affect the measurement reading. Handle the gage carefully to avoid dropping or scoring the precision ground surface, as any damage to the gage face will compromise measurement accuracy. Store the gage in its protective case or designated holder when not in use to prevent wear and corrosion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.575 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 29-575-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710538154290,"sku":"29-575-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b90a0bd720660eaa8822c471bdbbbc5a.jpg?v=1788467996","url":"https:\/\/voomisupply.com\/products\/spi-29-575-8-class-zz-plus-plug-gage-0-575-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
