Built from steel, it delivers a tolerance of 0.0002 inches, making it suitable for go\/no-go dimensional inspection work in manufacturing, machining, and quality control environments. Class ZZ is the standard tolerance class for plug gages used in production inspection, and the Plus designation indicates the gage is made to the upper half of the tolerance band. Machinists, quality technicians, and tool room professionals use plug gages like this one to confirm that drilled, reamed, or bored holes fall within specification before parts move to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use on precision machined components where hole diameter verification is required. It is appropriate for production floor inspection, incoming inspection, and tool qualification applications across metalworking, fabrication, and general manufacturing shops. At 0.2 pounds, it is a lightweight hand tool that integrates easily into standard inspection workflows without specialized fixtures or setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.899 inches for precise hole gauging\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for high-accuracy go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus designation — manufactured to the upper half of the ZZ tolerance band\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability in shop environments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for comfortable single-hand use during inspection\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 production and quality inspection applications requiring a 0.899-inch nominal bore diameter check.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are hand tools used by quality technicians and machinists and require no installation in the traditional sense. Before use, clean both the gage and the bore being inspected to remove chips, coolant, and debris that could affect the reading. Store the gage in its case when not in use and avoid dropping or striking the gage, as impact can alter the measuring surface. Periodic recalibration against traceable standards is recommended to maintain measurement integrity over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.899 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\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 29-899-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722731716914,"sku":"29-899-2","price":16.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f32656ea9f2742d45aed1a48f550e30_f58f7b45-5a86-4c30-b540-cd9dea1439ea.jpg?v=1788595112","url":"https:\/\/voomisupply.com\/products\/spi-29-899-2-class-zz-plus-plug-gage-0-899-in","provider":"Voomi Supply","version":"1.0","type":"link"}
