Built from steel, it delivers the dimensional accuracy required for precision inspection work in machine shops, manufacturing facilities, and quality control environments. Class ZZ Plus gages meet the tighter end of the ZZ tolerance range, making them suitable for applications where consistent, repeatable go\/no-go measurement is critical. Machinists, quality technicians, and tool-and-die professionals use this type of gage as a fast, reliable method to confirm bore size compliance without requiring CMM equipment.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in inspection of drilled, reamed, or bored holes where dimensional accuracy must be verified against a print tolerance. Typical applications include production floor inspection, incoming part verification, and tooling qualification. The steel construction holds up to repeated use in shop environments. It is suited for both job shop and production settings where hole diameter conformance is checked frequently against a nominal 0.669-inch specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class for high-accuracy go\/no-go hole inspection\u003c\/li\u003e\n  \u003cli\u003eNominal measurement diameter of 0.669 inches\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for precise dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in shop use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling at the inspection station\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for go\/no-go inspection of 0.669-inch nominal diameter holes in machined components.

Clean the gage and bore before use to remove chips, coolant, or debris that could affect the reading. Do not force the gage into an undersized hole, as this can damage the gage member and compromise calibration. Store the gage in its protective case when not in use to prevent wear and corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.669 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 (mm)\u003c\/strong\u003e: 0.0002 mm\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  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-669-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710349902130,"sku":"29-669-9","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04fe7c3cbdaf0d94770375f24209ebe3.jpg?v=1788465956","url":"https:\/\/voomisupply.com\/products\/spi-29-669-9-class-zz-plus-plug-gage-0-669-in","provider":"Voomi Supply","version":"1.0","type":"link"}
