With a nominal diameter of 0.455 inches and a minus tolerance of 0.0002 inches, this gage provides a reliable go\/no-go reference for confirming that a machined hole meets minimum size requirements. Constructed from steel, it is built to withstand repeated use in shop floor and inspection room environments. Machinists, toolmakers, and quality technicians use pin gages like this one as part of standard dimensional inspection workflows.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, manufacturing facilities, and inspection departments where hole diameter verification is required. It fits into standard pin gage sets or can be used as a standalone inspection tool. The Class ZZ tolerance class is appropriate for general-purpose inspection work where production gaging tolerances apply. Typical applications include checking drilled, reamed, or bored holes in metal and plastic workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.455 inches for direct bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches for general-purpose inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and inspection environments\u003c\/li\u003e\n  \u003cli\u003eMinus designation confirms the gage falls below nominal, functioning as a go gage reference\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, easy to handle during repetitive inspection tasks\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 suitable for use with standard pin gage handles and sets accepting 0.455 inch diameter pins.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages require no installation but should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Before use, verify the gage and workpiece are at a stable temperature, as thermal variation can affect dimensional readings. Store the gage in a protective case when not in use to prevent nicks or surface damage that would compromise accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.455 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: 19-455-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700351533362,"sku":"19-455-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b48fd91972262b040d5d68b937206d5.jpg?v=1788389287","url":"https:\/\/voomisupply.com\/products\/spi-19-455-5-class-zz-minus-plug-pin-gage-0-455-in","provider":"Voomi Supply","version":"1.0","type":"link"}
