It measures a nominal diameter of 0.243 inches with a minus tolerance of 0.0002 inches, conforming to Class ZZ standards for go\/no-go inspection work. Constructed from steel for durability and wear resistance, this pin gage is a standard tool in quality control and inspection environments. Machinists, toolmakers, and quality technicians use plug pin gages like this to verify hole sizes meet print tolerances before parts move to assembly or shipping.\u003c\/p\u003e\u003cp\u003eThis gage is suited for use in manufacturing, machine shops, and production inspection stations where hole diameter verification is required. It is appropriate for both low-volume and high-volume inspection tasks. Class ZZ gages are commonly used for general-purpose inspection where commercial-grade accuracy is sufficient. The 19-243-5 covers the 0.243-inch nominal hole size and is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ minus configuration for general-purpose hole inspection\u003c\/li\u003e\n\u003cli\u003e0.243-inch nominal diameter for precise bore verification\u003c\/li\u003e\n\u003cli\u003eTolerance of 0.0002 inches meets Class ZZ dimensional standards\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and long service life\u003c\/li\u003e\n\u003cli\u003eSingle-piece unit ready for immediate use in inspection applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for general-purpose inspection of 0.243-inch diameter holes in machined components across a wide range of manufacturing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug pin gages are used by machinists and quality control inspectors and do not require installation in the traditional sense. Ensure the gage and workpiece are at a stable ambient temperature before use, as thermal expansion can affect measurement accuracy. Clean the gage and hole being checked before each use to prevent debris from affecting readings. Handle with care to avoid drops or impacts that could alter the gage diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.243 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (minus)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 19-243-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694467612978,"sku":"19-243-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aaa37c81720d61f1b6a560a2bccd2b42.jpg?v=1788324627","url":"https:\/\/voomisupply.com\/products\/spi-19-243-5-class-zz-minus-plug-pin-gage-0-243-in","provider":"Voomi Supply","version":"1.0","type":"link"}
