Built from steel, it delivers a dimensional tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work on production floors, in machine shops, and in field quality-control applications. Machinists, quality inspectors, and tool-and-die professionals use plug gages like this one to confirm that drilled, reamed, or bored features meet print specifications before parts advance to the next stage of assembly or shipment.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for single-point diameter verification in manufacturing and inspection environments where consistent, repeatable measurement of 0.624-inch nominal bores is required. It is appropriate for use on steel, aluminum, plastic, and other workpiece materials where bore acceptance or rejection must be confirmed quickly and reliably. The Class ZZ Plus classification indicates a commercial-grade tolerance level commonly used for production inspection rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.624 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches (0.0051 mm) for reliable go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus classification — standard production inspection grade\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy bench or field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use plug gage for any application requiring verification of a 0.624-inch nominal bore diameter in standard production or inspection workflows.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality inspection personnel following standard metrology practices. Store the gage in a clean, dry location away from temperature extremes to prevent thermal expansion errors. Clean the gage and the bore being measured before use to avoid false readings caused by chips or debris. Apply light, consistent insertion force only — forcing a plug gage can damage both the gage and the workpiece bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 (0.0051 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: ZZ Plus\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: 29-624-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691101421874,"sku":"29-624-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd63d9e3c9e18c1ac6a73b3b575648a1.jpg?v=1788280378","url":"https:\/\/voomisupply.com\/products\/spi-29-624-4-class-zz-plus-plug-gage-0-624-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
