It holds a tolerance of 0.000200 inches, meeting Class ZZ specifications for go\/no-go dimensional inspection. Plug pin gages of this type are used in quality control, incoming inspection, and production line verification where accurate hole sizing is critical. Machinists, tool-and-die makers, and quality technicians rely on this style of gage for fast, repeatable pass\/fail checks without the need for indicating instruments.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspecting drilled, reamed, or bored holes in metal and plastic components across manufacturing, fabrication, and machine shop environments. The minus designation indicates the gage is ground to the low side of the nominal diameter, following standard plug gage practice for go-gage applications. It is appropriate for use on production floors and inspection benches where Class ZZ tolerances meet the required accuracy level for the work being inspected.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.949 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.000200 inches for consistent dimensional checking\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and inspection environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual replacement or addition to gage sets\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy bench and floor use\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 in any inspection or quality control application requiring verification of a 0.949-inch nominal hole diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages require no installation in the traditional sense but should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store the gage in a protective case away from other metal tools to avoid contact damage to the precision-ground surface. Verify the gage against a calibrated master ring gage or traceable standard before placing it into service. Follow your shop or facility calibration schedule to maintain measurement traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.949 inches\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\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: 19-949-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51701850603826,"sku":"19-949-7","price":16.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9157e42f15f0808878d99bd9417efde.jpg?v=1788405989","url":"https:\/\/voomisupply.com\/products\/spi-19-949-7-class-zz-minus-plug-pin-gage-0-949-in","provider":"Voomi Supply","version":"1.0","type":"link"}
