It is designed for go\/no-go gauging applications where bore diameter verification is required. The minus tolerance configuration holds the gage undersized relative to nominal, conforming to Class ZZ tolerance standards for general-purpose inspection work. With a tolerance of 0.0002 inches, it delivers the dimensional accuracy needed for production floor checks and incoming inspection. Machinists, quality control technicians, and tool room personnel are the primary users of this gage type.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is suited for verifying drilled, reamed, or bored holes in machined components across manufacturing and fabrication environments. It is applicable in both job shop and production settings where consistent bore qualification is required. The 0.557-inch diameter positions it for medium-range bore inspection tasks common in general machining, tooling, and assembly operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance class for general-purpose go\/no-go bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.557-inch nominal diameter for medium-range bore verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for reliable dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and shop durability\u003c\/li\u003e\n  \u003cli\u003eSingle-piece gage format for straightforward handheld use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for use with any go\/no-go gage handle or holder accepting 0.557-inch diameter pin gages in production and inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality technicians without specialized tooling for the gage itself. Clean the gage and the bore being checked before use to prevent debris from affecting the measurement. Store the gage in a protective case away from other metal tools to prevent nicks or surface damage that could affect tolerances. Follow ASME B89.1.5 or applicable shop standards for gage handling, calibration intervals, and acceptance criteria.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.557 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: Class ZZ Minus\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\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: 19-557-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722657759538,"sku":"19-557-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/049d98c81199877d94e0cb3fd8ed953e.jpg?v=1788594156","url":"https:\/\/voomisupply.com\/products\/spi-19-557-8-class-zz-minus-plug-pin-gage-0-557-in","provider":"Voomi Supply","version":"1.0","type":"link"}
