Built from steel, it measures a nominal diameter of 0.879 inches with a tolerance of 0.0002 inches, making it suited for go\/no-go dimensional verification tasks on the shop floor or in a quality control environment. This type of single-end pin gage is a standard tool for machinists, toolmakers, and quality technicians who need a reliable, consistent reference for checking hole size conformance to print specifications.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are the most common grade used in production inspection where high-precision laboratory-grade gages are not required. The 19-879-6 fits typical applications in manufacturing, fabrication, and machine shop environments where verifying a 0.879-inch nominal bore is part of routine part acceptance. It is appropriate for use on machined components, castings, and fabricated assemblies requiring dimensional verification at this diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance designation for production-grade go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003e0.879-inch nominal diameter for precise bore verification\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for consistent and repeatable measurement\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop-floor environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design compatible with standard pin gage handle sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use pin gage for standard handle-style plug gage sets accepting 0.879-inch diameter pins in production and inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages should be handled with clean cotton gloves or lint-free cloths to prevent corrosion from skin oils. Store in a protective case away from temperature extremes to maintain dimensional stability. When using in a handle-style gage set, confirm the collet or chuck is clean and secure before gauging. Follow your facility quality procedures and applicable ASME B89 standards for gage calibration and use intervals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.879 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  \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: 19-879-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695041577266,"sku":"19-879-6","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51152890d35235bb42513fdf09d2f6ef.jpg?v=1788330769","url":"https:\/\/voomisupply.com\/products\/spi-19-879-6-class-zz-minus-plug-pin-gage-0-879-in","provider":"Voomi Supply","version":"1.0","type":"link"}
