At 0.992 inches nominal diameter with a minus tolerance of 0.0002 inches, this go-style gage confirms whether a feature is within the lower boundary of the tolerance zone. Metrologists, machinists, and quality control technicians use plug gages like this one as a fast, reliable go\/no-go check during production inspection or incoming material verification. The steel construction provides the hardness and dimensional stability required for repeatable gauging in shop-floor environments.\u003c\/p\u003e\n\u003cp\u003eThe SPI 19-992-7 is suited for inspection of drilled, reamed, or bored holes in machined components across general manufacturing, tooling, and fabrication applications. Class ZZ gages are the most widely used working gage class for inspection of commercial-grade work where tight master-gage accuracy is not required. This gage is appropriate for any facility performing dimensional verification of holes near the 0.992-inch nominal size in steel, aluminum, or similar workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.992-inch nominal diameter for precise lower-limit hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches for standard working-gage accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for hardness and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eGo-style plug design enables fast pass\/fail checks without measurement instruments\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling at the inspection station\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 dimensional inspection of holes with a nominal diameter of 0.992 inches in general machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists, metrologists, and QC technicians — not installed in a system. Store the gage in a protective case away from other metal tools to prevent damage to the gauging surface. Clean the gage and the workpiece bore before use to ensure accurate readings and to prevent premature wear. Never force a plug gage into a hole; if the gage does not pass freely, the feature is out of tolerance on the low side.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.992 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\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: 19-992-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715163554098,"sku":"19-992-7","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f32656ea9f2742d45aed1a48f550e30_a864107b-0fe9-4bb1-ab5c-c18a9f285d42.jpg?v=1788509984","url":"https:\/\/voomisupply.com\/products\/spi-19-992-7-class-zz-minus-plug-pin-gage-0-992-in","provider":"Voomi Supply","version":"1.0","type":"link"}
