At 0.571 inches in diameter, this pin gage holds a tolerance of 0.0002 inches, placing it in the Class ZZ range appropriate for general inspection and quality control work. Plug pin gages are go\/no-go inspection tools used to confirm that a drilled, reamed, or bored hole falls within acceptable dimensional limits. Machinists, toolmakers, and quality control technicians use these gages as part of routine dimensional verification on production floors and in inspection rooms.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for dimensional inspection of machined components in manufacturing, fabrication, and toolroom environments. It is used where hole diameter verification is required to confirm conformance to engineering tolerances. The minus designation indicates the gage is ground to the low side of the nominal diameter, which is standard practice for go-gage applications. It is appropriate for use in both light production inspection and bench-level verification work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance classification for general-purpose inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to the low side of nominal diameter for go-gage applications\u003c\/li\u003e\n  \u003cli\u003e0.0002 inches tolerance for reliable dimensional verification\u003c\/li\u003e\n  \u003cli\u003e0.571 inches nominal diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production and toolroom environments\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 suitable for general inspection of bored, drilled, or reamed holes at 0.571 inches nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality control technicians and require no permanent installation. Store pin gages in a protective case away from moisture to prevent corrosion and protect the ground surface. Clean the gage and the workpiece bore before use to ensure accurate measurement readings. Handle with care to avoid dropping, which can alter the ground diameter and compromise gage accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.571 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: Class ZZ Minus\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: 19-571-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721333178674,"sku":"19-571-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36929549af1c8e8fa000bb5818e7a8c2.jpg?v=1788576585","url":"https:\/\/voomisupply.com\/products\/spi-19-571-9-class-zz-minus-plug-pin-gage-0-571-in","provider":"Voomi Supply","version":"1.0","type":"link"}
