Class ZZ gages are designed for general-purpose gauging applications where moderate tolerance control is required. This minus-type gage is ground to a tolerance of 0.0002 inches below nominal, making it suitable for go\/no-go inspection routines and incoming quality checks. Machinists, quality technicians, and tool room professionals use plug pin gages to verify bore diameters and hole sizes quickly and accurately without specialized metrology equipment.\u003c\/p\u003e\u003cp\u003eThis gage is appropriate for use in production floor inspection, machine shop quality control, and incoming material verification. The 0.624-inch size serves applications involving bored holes, drilled openings, and reamed passages in metal or plastic workpieces where tight dimensional conformance is required. The steel construction withstands repeated use in typical shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ tolerance class for general-purpose dimensional inspection\u003c\/li\u003e\n\u003cli\u003eMinus-type designation ground below nominal for go-gage applications\u003c\/li\u003e\n\u003cli\u003e0.0002-inch tolerance for reliable pass\/fail gauging\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under repeated shop use\u003c\/li\u003e\n\u003cli\u003e0.624-inch nominal diameter for common bore and hole verification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose plug pin gage suitable for use with standard gage handle holders and gage block accessories compatible with the 0.624-inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug pin gages should be handled and stored carefully to prevent nicks, burrs, or corrosion that could affect measurement accuracy. Clean the gage and the bore to be inspected before use to prevent debris from introducing measurement error. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. Periodic calibration against a traceable standard is recommended to maintain inspection integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.624 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\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: 19-624-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697096720690,"sku":"19-624-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20385e6158a815efa8da5359bf8ef295.jpg?v=1788349356","url":"https:\/\/voomisupply.com\/products\/spi-19-624-6-class-zz-minus-plug-pin-gage-0-624-in","provider":"Voomi Supply","version":"1.0","type":"link"}
