Manufactured from steel, this pin gage holds a tolerance of 0.0002 inches, placing it within the Class ZZ specification for working-grade gages used in general inspection applications. Technicians and quality control personnel use this gage to verify that a feature is at or above its minimum acceptable size, making it a standard tool in machining shops and maintenance facilities.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in manufacturing, fabrication, and maintenance inspection settings where accurate bore and hole verification is required. It is appropriate for checking clearance holes, pilot holes, and other cylindrical features in both metals and engineered plastics. The minus designation means the gage is ground to the lower boundary of the nominal size, consistent with standard plug gage practice for go-type applications. It is typically used by machinists, toolroom technicians, and quality inspectors working to drawing tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ working-grade tolerance for general production inspection\u003c\/li\u003e\n  \u003cli\u003e0.188-inch nominal diameter for precise bore and hole verification\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to the lower tolerance boundary\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for repeatable, accurate measurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a working-grade Class ZZ minus plug pin gage for use with standard go\/no-go gage handle sets accepting 0.188-inch diameter pin gages.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are handled by quality technicians and machinists and require no permanent installation. Before use, clean the gage and the feature being measured to remove chips, coolant, and debris that could affect reading accuracy. Store pin gages in a protective case away from other tools to prevent surface damage. Handle with care to avoid dropping, as impact can alter the ground diameter and invalidate the gage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesignation\u003c\/strong\u003e: 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  \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: 19-188-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700555874610,"sku":"19-188-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/172684e36fbfdb6fe4552975f8d02674.jpg?v=1788391902","url":"https:\/\/voomisupply.com\/products\/spi-19-188-2-class-zz-minus-plug-pin-gage-0-188-in","provider":"Voomi Supply","version":"1.0","type":"link"}
