Built from steel, this pin gage is manufactured to a minus tolerance of 0.0002 inches, which means the gage is intentionally made slightly below nominal to provide a go\/no-go reference for dimensional inspection. Metrology technicians, toolroom machinists, and quality control personnel use pin gages like this one to confirm that drilled, reamed, or punched hole features fall within specified tolerances during in-process and final inspection.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for dimensional inspection work in manufacturing, machining, and toolroom environments. It is used to check hole diameters in machined components, stampings, castings, and fabricated parts where tight dimensional control is required. The Class ZZ designation indicates a general-purpose inspection-grade gage appropriate for production floor use rather than laboratory-grade applications. The compact size and light weight of this pin make it easy to handle during repetitive inspection tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.1950 inches for precise hole and bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches for go\/no-go dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production and toolroom environments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use during inspection\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose Class ZZ grade suitable for production floor inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage for use in standard dimensional inspection applications where a 0.1950 inch nominal hole diameter must be verified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are precision instruments and should be handled with care to avoid nicks, burrs, or surface contamination that can affect measurement accuracy. Clean the gage and the feature being inspected before use, and apply a light instrument oil when storing to prevent corrosion. Do not force a pin gage into a hole that offers strong resistance, as this can damage both the gage and the workpiece. Store in a protective case away from other tooling to maintain gage integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.1950 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches minus\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: 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\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 19-195-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714517500210,"sku":"19-195-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0abcc46822bf4c00f42cfbe67223ca99.jpg?v=1788502596","url":"https:\/\/voomisupply.com\/products\/spi-19-195-7-class-zz-minus-plug-pin-gage-0-1950-in","provider":"Voomi Supply","version":"1.0","type":"link"}
