It is used to verify bore diameters and hole sizes by checking whether a machined feature meets its specified lower-limit tolerance. The minus designation means the gage is sized at the low end of the tolerance band, making it a go-gage reference in precision inspection workflows. With a tolerance of 0.0002 inches, this gage suits general-purpose dimensional inspection in manufacturing, maintenance, and quality-control environments. Machinists, toolmakers, and QC inspectors are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in production floor inspection, incoming quality checks, and fixture verification where a 0.447-inch nominal bore or hole feature must be confirmed within tight dimensional limits. It is suited for both ferrous and non-ferrous workpiece inspection. The compact, single-pin format allows use in tight clearances and is compatible with standard gage-handle holders commonly found in machine shops, maintenance facilities, and inspection labs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general-purpose inspection work\u003c\/li\u003e\n  \u003cli\u003eMinus designation provides lower-limit go-gage reference\u003c\/li\u003e\n  \u003cli\u003e0.0002 inches tolerance for accurate bore and hole verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production environments\u003c\/li\u003e\n  \u003cli\u003e0.447-inch nominal diameter suits a common bore size range\u003c\/li\u003e\n  \u003cli\u003eSingle-pin format compatible with standard gage handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose plug pin gage for use in standard gage handle holders sized for 0.447-inch diameter gage pins.

Before use, clean both the gage pin and the workpiece bore with a lint-free cloth to remove chips, coolant, and debris. Never force a plug gage into a hole; excessive insertion force can damage the gage or the workpiece and will produce unreliable readings. Store the gage in its protective case when not in use to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.447 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance 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\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: 19-447-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720739651890,"sku":"19-447-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a640c99584fe25cb5cc7580683d2d5d.jpg?v=1788568440","url":"https:\/\/voomisupply.com\/products\/spi-19-447-2-class-zz-minus-plug-pin-gage-0-447-in","provider":"Voomi Supply","version":"1.0","type":"link"}
