Manufactured from steel, this gage checks a nominal diameter of 0.9 inches with a tolerance of 0.0002 inches, making it suitable for applications where tight dimensional control is required. Class ZZ gages meet standard tolerances for general-purpose inspection work and are a common tool in quality control environments across machining, manufacturing, and fabrication shops.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production and inspection settings where hole diameter verification is part of the quality assurance process. It is appropriate for both in-process checks on the shop floor and final inspection before part acceptance. Machinists, quality technicians, and tool room professionals use Class ZZ plug gages to confirm that drilled, reamed, or bored holes fall within acceptable dimensional limits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.9 inch nominal measurement diameter\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for accurate dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suitable for individual or low-volume procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for inspection of 0.9 inch nominal diameter holes in general machining and manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists during inspection operations. Before use, clean the gage and the hole being measured to remove chips, coolant, or debris that could affect accuracy. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Store the gage in its protective case when not in use to prevent surface damage and maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (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\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: 29-900-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714211348786,"sku":"29-900-8","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c73d81368c29049af85735c8c243c28b.jpg?v=1788497567","url":"https:\/\/voomisupply.com\/products\/spi-29-900-8-class-zz-plus-plug-gage-0-9-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
