Built from steel, this go\/no-go style gage checks whether a drilled, reamed, or otherwise machined bore falls within an acceptable tolerance band. The gage carries a tolerance of 0.0002 inches (0.0002 mm), meeting Class ZZ Plus standards appropriate for inspection of standard-tolerance production holes. Machinists, quality control inspectors, and toolroom technicians use plug gages like this one as a fast, reliable alternative to variable-measurement instruments when a pass\/fail check is sufficient.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited to production floor and toolroom inspection environments where small-diameter bores must be verified quickly and repeatedly. At 0.089 inches nominal diameter, it covers a common range used in precision machining applications including jig and fixture work, small-bore hydraulic and pneumatic fittings, and instrument-body drilling. The compact size and light weight make it easy to handle during high-volume inspection runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.089 inches for precise small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches ensures consistent, repeatable pass\/fail results\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and resistance to wear during repeated use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, reducing hand fatigue during extended inspection sessions\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity supports individual replacement or spot inspection needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom plug gage for applications requiring Class ZZ Plus inspection of bores at 0.089 inches nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and stored by quality technicians and machinists following standard metrology practices. Always clean and dry the gage and the bore before use to prevent false readings from chips, coolant, or debris. Store the gage in its case away from temperature extremes to maintain dimensional stability. Do not force the gage into an undersize bore, as this will damage the gage and produce unreliable results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.089 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\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: 29-089-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690322854194,"sku":"29-089-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48ba26c00a68f6e8cb5e8e1b7d227deb.jpg?v=1788268753","url":"https:\/\/voomisupply.com\/products\/spi-29-089-0-class-zz-plus-plug-gage-0-089-in","provider":"Voomi Supply","version":"1.0","type":"link"}
