Designed to verify hole sizes and bore diameters, this pin gage checks whether a feature meets its specified lower-limit tolerance. At 0.658 inches in diameter with a tolerance of 0.000200 inches, it provides the accuracy needed for go\/no-go inspection routines in production and maintenance environments. Machinists, quality technicians, and tool-and-die professionals rely on Class ZZ pin gages as an economical standard for general-purpose hole checking.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for use in manufacturing facilities, machine shops, and maintenance departments where frequent hole inspection is required. It applies to ferrous and non-ferrous workpieces where bore size verification is part of an inspection process. The minus designation means the gage is ground to the lower boundary of the nominal diameter, making it appropriate for checking minimum acceptable hole size in standard go\/no-go gage setups. Single-pin packaging makes it straightforward to replace or supplement an existing gage set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general-purpose dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to the lower boundary of the nominal diameter\u003c\/li\u003e\n  \u003cli\u003e0.000200 inch tolerance for reliable go\/no-go measurement\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003e0.658 inch nominal diameter for precise bore verification\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 use with conventional pin gage handles and gage blocks in general-purpose hole inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are handled and used by quality technicians and machinists following standard metrology practices. Clean the gage and the workpiece bore before use to prevent debris from affecting measurement accuracy. Store pin gages in a protective case away from other tools to avoid surface damage that could compromise tolerance accuracy. Do not force a pin gage into a bore; light hand pressure is the correct technique for go\/no-go checks.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.658 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.000200 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\u003eTolerance 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  \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: 19-658-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698023072050,"sku":"19-658-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4874d456dbff19511598071869a9a56.jpg?v=1788356857","url":"https:\/\/voomisupply.com\/products\/spi-19-658-4-class-zz-minus-plug-pin-gage-0-658-in","provider":"Voomi Supply","version":"1.0","type":"link"}
