Plug pin gages are precision measuring tools used to verify hole diameters, bore sizes, and slot widths to a defined tolerance. The Class ZZ designation indicates a standard-grade tolerance gage suitable for inspection and quality control work in production environments. This gage carries a minus tolerance of 0.0002 inches, meaning the actual pin diameter is ground slightly below the nominal size to confirm a minimum hole condition. Machinists, toolmakers, and quality control technicians use plug pin gages as part of go\/no-go inspection procedures.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for dimensional inspection in manufacturing, machine shops, fabrication facilities, and toolrooms. It is used to verify that drilled, reamed, or bored holes meet minimum diameter requirements before assembly or further machining. The 0.508-inch nominal size corresponds to common bore and hole specifications encountered in general machining and light industrial applications. Its steel construction provides durability for repeated use in shop floor inspection routines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.508 inches for direct go\/no-go hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches ground below nominal\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSingle-piece pin gage format for straightforward handling and use\u003c\/li\u003e\n  \u003cli\u003ePackaged individually for single-gage inspection setups\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 use in go\/no-go inspection setups requiring a 0.508-inch nominal hole diameter check.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality control technicians and do not require power or mechanical installation. Clean and lightly oil the pin before and after use to prevent corrosion and protect the ground surface. Do not force the gage into an undersized hole, as this can damage the ground surface and alter the calibrated diameter. Store the gage in a protective case away from other metal tooling to prevent contact damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.508 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\u003eTolerance (Decimal Inch)\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 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\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: 19-508-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692644401458,"sku":"19-508-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91728f47499856f78fd43cb49071fb40.jpg?v=1788300495","url":"https:\/\/voomisupply.com\/products\/spi-19-508-1-class-zz-minus-plug-pin-gage-0-508-in","provider":"Voomi Supply","version":"1.0","type":"link"}
