Plug pin gages in the ZZ class are the standard go\/no-go precision tools used to verify bore and hole diameters in machined parts and assemblies. The minus tolerance designation means the gage is ground to the lower end of the allowable tolerance band, with a tolerance of 0.0002 inches. This gage weighs 0.2 pounds and is suited for quality control, inspection, and toolroom applications where accurate hole verification is required.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are used primarily in production and inspection environments to check hole size conformance in metal, plastic, and composite workpieces. The 0.525-inch diameter makes this gage suitable for checking mid-range bored holes and drilled passages. Typical users include machinists, quality assurance inspectors, and toolroom technicians working in manufacturing, job shop, and industrial maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance designation for inspection and production-grade gauging\u003c\/li\u003e\n  \u003cli\u003e0.525-inch diameter for precise bore and hole verification\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for repeatable dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use during 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 use in go\/no-go inspection of 0.525-inch diameter holes and bores in machined components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by quality inspectors and machinists and require no permanent installation. Before use, clean both the gage and the workpiece bore to remove chips, oils, or debris that could affect measurement accuracy. Do not force the gage into a hole; if resistance is felt, the bore is undersized or contaminated. Store the gage in a protective case away from moisture and temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.525 inches\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\u003eClass\u003c\/strong\u003e: 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: 19-525-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51707127071026,"sku":"19-525-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cefceb7d913b1eb7b59e34a14f7be0f4.jpg?v=1788438499","url":"https:\/\/voomisupply.com\/products\/spi-19-525-5-class-zz-minus-plug-pin-gage-0-525-in","provider":"Voomi Supply","version":"1.0","type":"link"}
