Built from hardened steel, this go-type gage is used to confirm that a bore or hole falls within the specified lower tolerance boundary. The minus designation means the gage is manufactured to the low side of the nominal dimension, with a tolerance of 0.0002 inches. Machinists, quality control technicians, and toolroom professionals use plug pin gages like this one as a fast, reliable method for in-process and final inspection of drilled, reamed, or bored features.\u003c\/p\u003e\u003cp\u003eThis gage is suited for use in precision machining, metalworking, and quality inspection environments where tight dimensional control is required. It is appropriate for both job-shop and production-floor inspection of ferrous and non-ferrous workpieces. The 0.811-inch diameter size is a standard inch-series gage applicable to a wide range of mechanical components and tooling setups requiring verification of that nominal bore dimension.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ tolerance class — designed for general-purpose inspection and toolroom use\u003c\/li\u003e\n\u003cli\u003eMinus plug configuration checks the lower tolerance boundary of a bore or hole\u003c\/li\u003e\n\u003cli\u003eTolerance of 0.0002 inches provides reliable dimensional verification\u003c\/li\u003e\n\u003cli\u003e0.811-inch nominal diameter in hardened steel construction\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.2 pounds for easy handheld use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose inch-series plug pin gage for inspecting holes and bores with a nominal diameter of 0.811 inches in standard machining and quality control applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug pin gages are handled and used by machinists and quality control inspectors, not installed in a permanent sense. Clean the gage and the bore being checked before use to avoid false readings caused by debris or cutting fluid residue. Do not force the gage into a hole — if it does not enter freely, the bore is undersize. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: Class ZZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Minus Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 19-811-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720464728370,"sku":"19-811-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bad15d3295c0e84cbaa9a9dd1e53e8b8.jpg?v=1788564427","url":"https:\/\/voomisupply.com\/products\/spi-19-811-9-class-zz-minus-plug-pin-gage-0-811-in","provider":"Voomi Supply","version":"1.0","type":"link"}
