Plug gages of this class are go\/no-go inspection tools used to confirm that machined features fall within specified dimensional limits. The steel construction provides durability under repeated use in shop-floor and toolroom inspection environments. Machinists, quality control technicians, and tool-and-die professionals rely on this type of gage for fast, reliable attribute inspection without requiring a measuring instrument readout.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for dimensional inspection of drilled, reamed, or bored holes in production and toolroom settings. It is appropriate for both light-manufacturing and precision-machining environments where hole-size conformance must be verified quickly against a fixed tolerance. The 0.578-inch nominal diameter makes it a direct-fit inspection tool for that specific bore specification. It is typically used as part of a go\/no-go gage set or as a standalone check gage at an inspection station.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.578 inches for direct bore inspection at that dimension\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for precise attribute gauging\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for bench-top and in-process inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual replacement or targeted inspection use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inspection gage for any application requiring attribute gauging of a 0.578-inch nominal bore diameter to Class ZZ Plus standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are hand-held inspection tools and do not require installation in the traditional sense. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store in a protective case or pouch when not in use to protect the precision-ground surface from damage. Calibration and periodic certification should be performed in accordance with applicable metrology standards and quality system requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.578 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage 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\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: 29-578-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691962663218,"sku":"29-578-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a60cf5d96cd2f9948c762a0f148f0af0.jpg?v=1788291469","url":"https:\/\/voomisupply.com\/products\/spi-29-578-2-class-zz-plus-plug-gage-0-578-in","provider":"Voomi Supply","version":"1.0","type":"link"}
