Manufactured from steel, this go-no-go style gage is designed for dimensional verification where consistent, repeatable measurement is required. The 0.898-inch nominal diameter and a minus tolerance of 0.000200 inches (0.0002 mm) place it within Class ZZ specifications, the standard for general-purpose inspection gages used in tool rooms, machine shops, and quality control environments. Machinists, quality technicians, and tool-and-die professionals use pin gages like this to confirm that machined holes fall within acceptable dimensional limits before assembly or final inspection.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for use in manufacturing facilities, machine shops, and quality assurance departments handling parts that require close-tolerance bore verification. The 0.898-inch diameter makes it appropriate for inspecting medium-range bore sizes in components produced on CNC equipment, conventional lathes, or boring mills. It is commonly used as part of a gage pin set or as a standalone replacement pin when a single diameter needs to be verified in a recurring inspection process.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general-purpose hole and bore inspection\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance designation: 0.000200 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e0.898-inch nominal diameter for medium-range bore verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repeated-use inspection environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual replacement or standalone use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage for use in standard tool room and production inspection applications requiring a 0.898-inch nominal bore diameter check.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are handled and used by quality technicians and machinists during inspection, not installation into a mechanical system. Clean the gage and the bore to be checked before use to prevent debris from affecting measurement accuracy. Never force a plug gage into a hole; if resistance is felt, the bore may be undersize or contain burrs that require attention. Store pin gages in a protective case away from other metal tools to prevent surface damage that could compromise measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.898 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 (Decimal Inch)\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\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: 19-898-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689886220594,"sku":"19-898-6","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c144455a788e4942494e737ad53c7f4.jpg?v=1788265162","url":"https:\/\/voomisupply.com\/products\/spi-19-898-6-class-zz-minus-plug-pin-gage-0-898-in","provider":"Voomi Supply","version":"1.0","type":"link"}
