Machined from steel, this go\/no-go style gage checks whether a bore falls within acceptable tolerance limits. It is designed for workshop and production-floor inspection where fast, repeatable measurement is required. The nominal diameter is 0.572 inches with a bilateral tolerance of 0.0002 inches, placing it in the Class ZZ Plus accuracy tier appropriate for general-purpose dimensional inspection. Machinists, toolmakers, and quality-control technicians use plug gages as part of standard in-process and final inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in manufacturing, machine shops, and precision fabrication environments. It is applied during inspection of drilled, reamed, or bored holes where dimensional conformance must be confirmed before assembly. The 0.572-inch nominal size fits applications requiring close-tolerance hole verification in steel, aluminum, and similar materials. A single unit is supplied per package, making it practical for individual inspection station use or as a replacement gage in an existing set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.572 inches for targeted 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 durability and wear resistance under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand handling\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual station or replacement use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision measurement tool for use in any inspection application requiring a 0.572-inch nominal diameter Class ZZ Plus plug gage.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by quality-control technicians and machinists and require no power source or special tools to operate. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the gage into a bore, as this can damage the gage surface or produce false readings. Handle with care and store separately from other tooling to avoid nicks or wear that would affect measurement reliability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.572 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy 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: 29-572-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692783436082,"sku":"29-572-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a191bbf85acff631baae8a75f547c576.jpg?v=1788302826","url":"https:\/\/voomisupply.com\/products\/spi-29-572-5-class-zz-plus-plug-gage-0-572-in","provider":"Voomi Supply","version":"1.0","type":"link"}
