Plug pin gages are precision inspection tools used to verify that a drilled, reamed, or bored hole falls within a specified dimensional range. The Class ZZ designation indicates a working-gage tolerance grade suitable for general inspection applications in production and maintenance environments. The steel construction provides the hardness and dimensional stability required for repeatable contact measurement across high-use inspection cycles.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in machine shops, manufacturing facilities, and maintenance shops where hole diameter verification is a routine quality-control step. It is appropriate for checking holes in metal, plastic, and composite workpieces where the nominal hole size is 0.183 inches. Machinists, quality-control inspectors, and toolroom technicians are the primary users. The minus designation means the gage is ground to the low side of the nominal diameter, which is the standard configuration for a go-gage application confirming minimum material condition.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.183 inches for direct hole-size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade at 0.0002 inches for general production inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to the low side of nominal for go-gage use\u003c\/li\u003e\n  \u003cli\u003eSteel construction for hardness and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece gage format for straightforward handheld inspection\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 general-purpose hole inspection where a nominal diameter of 0.183 inches is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are hand-applied tools and require no installation. Insert the gage into the test hole with light hand pressure only — never force or hammer a pin gage. Clean both the gage and the workpiece hole before use to prevent false readings caused by debris or burrs. Store pin gages in a protective case away from temperature extremes to maintain dimensional accuracy over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.183 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: 19-183-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698806456626,"sku":"19-183-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82fe63f2117898e5a29ada0a1f4622f7.jpg?v=1788368219","url":"https:\/\/voomisupply.com\/products\/spi-19-183-3-class-zz-minus-plug-pin-gage-0-183-in","provider":"Voomi Supply","version":"1.0","type":"link"}
