It measures holes at a nominal diameter of 0.535 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work in production and maintenance environments. Machined from steel for durability and dimensional stability, this plug gage is a standard tool for quality control technicians, tool-and-die makers, and machinists who need reliable, repeatable hole inspection without the variability of calipers or bore gauges.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in machine shops, manufacturing facilities, and maintenance departments wherever hole diameter verification is required. It is suited for inspecting holes in metal components, fixtures, and assemblies where tight dimensional control is necessary. The Class ZZ tolerance class is appropriate for general-purpose production inspection, making this gage a practical choice for incoming inspection, in-process quality checks, and final part verification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.535 inches for targeted hole inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for precise go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus designation meets standard general-purpose inspection requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides dimensional stability and long service life\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling at the workstation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ plug gage for use in any production or maintenance inspection application requiring verification of a 0.535-inch nominal hole diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality control technicians and machinists and require no permanent installation. Before use, clean the gage and the hole being inspected to remove chips, coolant, and debris that could affect the reading. Store the gage in its protective case when not in use to prevent damage to the ground surfaces. Periodic recalibration against a certified master is recommended to maintain traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.535 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\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: 29-535-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691806294322,"sku":"29-535-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d713068407addb24c870538408bc8d2.jpg?v=1788289965","url":"https:\/\/voomisupply.com\/products\/spi-29-535-2-class-zz-plus-plug-gage-0-535-in","provider":"Voomi Supply","version":"1.0","type":"link"}
