This gage checks whether a 0.897-inch diameter hole meets specified tolerances by passing or rejecting the workpiece at the go end. Built from steel, it holds a tolerance of 0.0002 inches, consistent with Class ZZ standards for general-purpose inspection. Machinists, quality control technicians, and toolroom personnel use this gage as a fast, reliable method for dimensional verification without the need for complex measuring equipment.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are widely used in manufacturing, job shops, and inspection departments where hole size conformance must be confirmed quickly and repeatedly. The 19-897-8 is suited for checking bored, drilled, or reamed holes in metal, plastic, or composite workpieces where a 0.897-inch nominal diameter is specified. It is appropriate for both production floor use and bench inspection tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance classification for general-purpose go or no-go hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.897-inch nominal diameter for direct size verification\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for consistent, repeatable measurement results\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and inspection environments\u003c\/li\u003e\n  \u003cli\u003eCompact, single-unit design for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard inspection tool for applications requiring Class ZZ minus plug pin gages at 0.897-inch nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by machinists and quality technicians without power tools or energy sources, so no lockout or shutoff procedures apply. Handle the gage carefully to avoid dropping or striking it, as impact can alter the ground surface and affect accuracy. Clean the gage and the workpiece bore before use to prevent debris from causing false rejections. Store the gage in a protective case away from other metal tooling to prevent nicks and corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.897 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 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\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: 19-897-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717421695282,"sku":"19-897-8","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72fdc47a623f7c4a8c4ca86f81d5c2b6.jpg?v=1788540152","url":"https:\/\/voomisupply.com\/products\/spi-19-897-8-class-zz-minus-plug-pin-gage-0-897-in","provider":"Voomi Supply","version":"1.0","type":"link"}
