It measures a nominal diameter of 0.648 inches with a tolerance of 0.0002 inches, meeting Class ZZ Plus standards for precision measurement in shop-floor and inspection environments. Constructed from steel, this gage provides the durability and wear resistance required for repeated use in production settings. Machinists, quality control technicians, and tool-and-die professionals rely on plug gages like this to verify hole size conformance quickly and without the need for complex measurement setups.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in machine shops, manufacturing facilities, and maintenance environments where accurate hole verification is required. It is used to inspect bored, drilled, or reamed holes in metal components, ensuring that finished parts meet dimensional tolerances before assembly. The 0.648-inch diameter targets a specific hole size common in precision machined parts, and the Class ZZ Plus classification makes it appropriate for general-purpose inspection work where close-tolerance verification is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.648 inches for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches, conforming to Class ZZ Plus standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design suitable for go\/no-go inspection workflows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ Plus plug gage for inspecting holes with a nominal diameter of 0.648 inches in machined metal components across a variety of manufacturing and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are used by machinists and quality control technicians and require no installation, but proper handling is essential for accurate results. Clean both the gage and the hole being inspected before use to prevent contamination from chips or debris that can affect readings. Store the gage in its case or on a padded surface to protect the precision ground surface from damage. Handle with clean, dry hands or inspection gloves to prevent corrosion from skin oils.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.648 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: 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: 29-648-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699877282098,"sku":"29-648-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3eb1509628691959bab0cd7de78e1a34.jpg?v=1788382439","url":"https:\/\/voomisupply.com\/products\/spi-29-648-3-class-zz-plus-plug-gage-0-648-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
