It checks whether a hole accepts or rejects the nominal 0.809-inch diameter within a tolerance of 0.0002 inches. Machined from steel, this go\/no-go style gage gives machinists and quality-control technicians a fast, reliable method for in-process or final inspection without requiring a measuring instrument at the point of check. It is a standard single-end cylindrical plug gage suited for precision hole verification in manufacturing, repair, and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis gage is used wherever a 0.809-inch nominal hole diameter must be confirmed to close tolerance. Typical applications include machine shops, toolrooms, production lines, and maintenance facilities performing work on hydraulic components, motor housings, bearing bores, or other precision-machined parts. It is handled by machinists, quality inspectors, and tool-and-die technicians performing dimensional verification on ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.809 inches for direct hole verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for high-accuracy go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability during repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.2 pounds for easy one-hand operation\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design simplifies inspection workflow without additional setup\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 any application requiring inspection of a 0.809-inch nominal diameter hole to Class ZZ Plus gage tolerance standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages require no installation but should be handled with clean, dry hands or lint-free gloves to prevent corrosion and contamination of the gage surface. Verify the workpiece is at ambient temperature before gauging, as thermal expansion can affect readings. Store the gage in its protective case when not in use to prevent surface damage. Calibration and use should follow applicable ASME B89 or equivalent dimensional metrology standards for your facility.\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: 0.809 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: 29-809-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51716972577074,"sku":"29-809-1","price":15.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/798c3cf92582c7f0738a80e4d0c59c96.jpg?v=1788534220","url":"https:\/\/voomisupply.com\/products\/spi-29-809-1-class-zz-plus-plug-gage-0-809-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
