Plug pin gages are precision measurement tools used to verify the diameter of bored holes, machined ports, and other cylindrical features. The Class ZZ designation indicates a working-grade gage appropriate for production inspection and shop-floor dimensional verification. Constructed from steel, this gage provides the rigidity and wear resistance required for repeated use in industrial and manufacturing environments. It is handled by machinists, quality control inspectors, and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for production floor and inspection room applications where hole diameter must be confirmed to close tolerances. It is used to check machined components, castings, and fabricated parts during in-process and final inspection. The minus designation means the gage is ground to the lower boundary of the nominal size, making it appropriate for go-gage applications where confirming minimum acceptable hole size is required. It is a standard single-piece pin gage compatible with common pin gage handle sets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.859-inch nominal diameter for precise hole verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ working-grade tolerance of 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003eMinus designation for go-gage lower-limit inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard pin gage handle sets\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 for use with common pin gage handle sets in production inspection and shop-floor dimensional verification applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are installed and used by machinists and quality control inspectors. Before use, clean both the gage and the part bore with a lint-free cloth to remove oil, chips, and debris that could affect measurement accuracy. Handle the gage with care to avoid dropping, as impact can alter the ground diameter. Store pin gages in a protective case away from other tools to prevent surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.859 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\u003eClass\u003c\/strong\u003e: 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: 19-859-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51708467347762,"sku":"19-859-8","price":16.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8aaa4b753d032d357191e486f16f908.jpg?v=1788446434","url":"https:\/\/voomisupply.com\/products\/spi-19-859-8-class-zz-minus-plug-pin-gage-0-859-in","provider":"Voomi Supply","version":"1.0","type":"link"}
