Plug pin gages are single-end or double-end hardened steel gauging tools used to verify that a hole or bore falls within a specified dimensional range. The Class ZZ designation indicates a standard commercial-grade tolerance class commonly used for inspection of production parts where close-tolerance metrology is required. The minus configuration means the gage is manufactured at the lower boundary of the tolerance band, allowing technicians to verify minimum acceptable hole size. This gage is constructed from steel for durability and dimensional stability under repeated use.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in manufacturing, machining, and inspection environments where hole size must be confirmed to print specifications. Typical applications include incoming inspection, in-process quality control, and final inspection of drilled, reamed, or bored holes. Machinists, quality technicians, and tool-and-die professionals use Class ZZ gages for general production inspection work where gage-maker tolerance classes such as X or XX are not required. The 0.945-inch diameter makes this gage suitable for medium-bore inspection tasks across a range of metal, plastic, and composite workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.945 inches for medium-bore hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance class rated for general production inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus plug configuration checks minimum acceptable hole boundary\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for reliable dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and long service life under repeated gauging cycles\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 any inspection application requiring verification of a 0.945-inch nominal bore diameter in general production and quality control settings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by quality technicians and machinists following standard metrology practices. Store gages in a protective case away from temperature extremes and contaminants to preserve dimensional accuracy. Clean the gage and the bore being checked before use to prevent debris from affecting readings. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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: 19-945-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700726071602,"sku":"19-945-5","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b90066484fb316b42af96afbf9824c02.jpg?v=1788394423","url":"https:\/\/voomisupply.com\/products\/spi-19-945-5-class-zz-minus-plug-pin-gage-0-945-in","provider":"Voomi Supply","version":"1.0","type":"link"}
