Plug gages of this class are used for go\/no-go inspection of drilled, reamed, or bored holes where dimensional accuracy must be confirmed before assembly. The 29-263-1 is constructed from steel for durability and dimensional stability under repeated use. This gage is a standard tool in quality control environments and on the shop floor, used by machinists, QC inspectors, and toolmakers who need reliable, repeatable bore verification without relying on measuring instruments subject to operator technique.\u003c\/p\u003e\n\u003cp\u003eClass ZZ Plus plug gages are suited for general-purpose inspection in manufacturing and production settings. The 0.263-inch diameter range makes this gage applicable to common fractional and decimal bore sizes used in light machining, small component assembly, and precision part inspection. It is appropriate for both in-process checks and final inspection of workpieces in machine shops, production lines, and maintenance facilities where bore size conformance is a critical quality checkpoint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus accuracy rating for reliable go\/no-go bore inspection\u003c\/li\u003e\n  \u003cli\u003eMeasurement diameter: 0.263 inches\u003c\/li\u003e\n  \u003cli\u003eTolerance: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003eSteel construction for dimensional stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suitable for individual tooling orders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for general-purpose go\/no-go inspection of bores measuring 0.263 inches in diameter across common machining and manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by machinists and QC inspectors following standard metrology practices. Before use, clean the gage and the bore being inspected to remove chips, coolant, or debris that could affect measurement accuracy. Store the gage in its protective case and avoid dropping or stacking it with other tooling to prevent nicking the precision ground surface. Periodic calibration against certified masters is recommended to maintain measurement traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.263 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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: 29-263-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696426484018,"sku":"29-263-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90c5802313896a66ff7c4145bba2682c.jpg?v=1788342549","url":"https:\/\/voomisupply.com\/products\/spi-29-263-1-class-zz-plus-plug-gage-0-263-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
