Built from steel, this pin gage holds a tolerance of 0.0002 inches and is sized at 0.553 inches in diameter. It is a minus-type gage, meaning the pin is manufactured to the low side of the nominal diameter, making it suitable for checking minimum hole size acceptance. Machinists, quality control technicians, and tool room professionals use plug pin gages as a reliable, hands-on method for confirming bore dimensions during production and incoming inspection workflows.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug pin gages are the standard working-grade gage for general shop and production inspection use. The 19-553-7 is suited for applications where a 0.553-inch nominal bore diameter must be confirmed to print tolerance. Typical use cases include checking drilled, reamed, or bored holes in metal or plastic components across light manufacturing, machining, and assembly environments. This gage is appropriate for bench inspection stations and in-process checks on the shop floor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ working-grade accuracy for general production inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation — pin ground to the low side of nominal for minimum bore verification\u003c\/li\u003e\n  \u003cli\u003e0.553-inch nominal diameter for direct go\/no-go hole checking\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for consistent, repeatable measurements\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and bench environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit — no assembly required out of the package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style working gage for use in any shop or inspection environment requiring verification of 0.553-inch nominal bore diameters to Class ZZ minus standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages require no installation but should be handled and stored with care to avoid surface damage that could affect dimensional accuracy. Clean the gage and the bore being checked before use to remove chips, coolant, or debris. Allow the gage and workpiece to reach the same ambient temperature before measuring, as thermal expansion can affect readings at tight tolerances. Calibration and periodic re-verification against a master standard are recommended practices per ISO and ASME gage inspection guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.553 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 19-553-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693886472498,"sku":"19-553-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b836c72867b145bdea49453aced9c54.jpg?v=1788318580","url":"https:\/\/voomisupply.com\/products\/spi-19-553-7-class-zz-minus-plug-pin-gage-0-553-in","provider":"Voomi Supply","version":"1.0","type":"link"}
