Built to Class ZZ Plus tolerance standards, this gage holds a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection of production parts where dimensional accuracy is critical. The steel construction provides durability and wear resistance for repeated use in a shop or quality-control environment. Machinists, toolmakers, and quality inspectors rely on this type of gage for fast, reliable in-process and final inspection checks.\u003c\/p\u003e\u003cp\u003eThis plug gage is intended for use in manufacturing, machine shop, and inspection environments where bore diameter verification is required. It is used to check holes and bores machined to a 0.349-inch nominal dimension. The gage is suited for both in-process inspection at the machine and final inspection at a quality-control station. Its compact size and single-end design make it easy to handle during high-volume inspection tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNominal measurement diameter of 0.349 inches for precise bore inspection\u003c\/li\u003e\n\u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable go\/no-go gauging\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance and long service life\u003c\/li\u003e\n\u003cli\u003eCompact form factor suits both bench inspection and in-process use\u003c\/li\u003e\n\u003cli\u003eSingle-piece quantity allows for targeted replacement or addition to an existing gage set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for inspecting machined bores and holes with a nominal diameter of 0.349 inches in general manufacturing and quality-inspection applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are handled and used by machinists, toolmakers, and quality-control technicians — no power source or tool disassembly is required. Clean the gage and the bore being checked before use to prevent debris from affecting the reading. Handle with care to avoid drops or impacts, which can alter the gage surface and compromise accuracy. Periodic calibration against a certified reference standard is recommended to maintain traceability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.349 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 29-349-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51708241707314,"sku":"29-349-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94d300672ede13873b101be914268273.jpg?v=1788445052","url":"https:\/\/voomisupply.com\/products\/spi-29-349-8-class-zz-plus-plug-gage-0-349-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
