This gage measures 0.19 inches in diameter and holds a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work where dimensional accuracy is critical. Constructed from steel, it delivers the wear resistance and dimensional stability required for repeated use in shop-floor environments. Machinists, toolroom technicians, and quality control inspectors use this type of gage to confirm that drilled, reamed, or bored holes meet print specifications before parts move to the next operation.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is designed for use in manufacturing, machining, and inspection settings where hole size verification is part of the standard quality process. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection of production parts. The minus designation means the gage is ground to the low side of the nominal diameter, which is the standard configuration for a go gage application. It is suited for use with standard gage blocks, pin gage sets, and handle accessories in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general-purpose production inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to the low side of nominal for go gage use\u003c\/li\u003e\n  \u003cli\u003e0.19 inch nominal diameter for direct hole verification at that size\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for repeatable and accurate measurement results\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under shop conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use Class ZZ minus plug pin gage for 0.19 inch diameter hole inspection applications in standard machining and quality control environments.\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 following standard metrology practices. Clean the gage and the hole being inspected before use to prevent measurement errors caused by debris or burrs. Store the gage in a protective case away from other tools to avoid surface damage that could affect accuracy. Handle with care and avoid dropping, as impact can alter the ground diameter and invalidate the gage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (Decimal Inch)\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\u003eGage Class\u003c\/strong\u003e: Class ZZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Minus Plug Pin Gage\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: 19-190-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721323741490,"sku":"19-190-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c62c9121c0e40e2cebd70f70be193e93.jpg?v=1788576460","url":"https:\/\/voomisupply.com\/products\/spi-19-190-8-class-zz-minus-plug-pin-gage-0-19-in","provider":"Voomi Supply","version":"1.0","type":"link"}
