Plug gages are go\/no-go measurement tools used to verify that a drilled, reamed, or bored hole falls within an acceptable diameter range. This gage is constructed from steel, providing the dimensional stability required for repeated use in production and inspection environments. Machinists, quality control technicians, and tool-and-die professionals use Class ZZ Plus gages when consistent hole-size verification is required on the shop floor or in an inspection department.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in manufacturing, fabrication, and machine shop environments where hole diameter conformance must be verified against a known standard. It is appropriate for both incoming inspection and in-process quality checks on steel, aluminum, and other common workpiece materials. The 0.647-inch nominal size targets bore dimensions common in precision mechanical assemblies. Each unit is packaged individually and intended for single-gage deployment rather than a set configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.647 inches for targeted bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches ensures accurate go\/no-go determination\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability 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-unit packaging supports individual gage replacement or supplemental tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental gage for inspection setups requiring a Class ZZ Plus plug gage at 0.647 inches nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are typically deployed by machinists or quality technicians and require no installation in the traditional sense. Before use, ensure the gage and the workpiece bore are clean and free of chips, coolant residue, and burrs to prevent false readings or gage wear. Handle the gage with care to avoid dropping, as impact can alter the precision ground surface. Store the gage in a protective case or designated gage block when not in use to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.647 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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: 29-647-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692132139314,"sku":"29-647-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0a6668e4200678663ed14ea7f1605ae.jpg?v=1788293521","url":"https:\/\/voomisupply.com\/products\/spi-29-647-5-class-zz-plus-plug-gage-0-647-in","provider":"Voomi Supply","version":"1.0","type":"link"}
