It measures a nominal diameter of 0.163 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection workflows where tight dimensional control is required. The gage is constructed from steel for durability and dimensional stability. Machinists, quality control technicians, and tool-and-die professionals use this type of gage to verify that drilled, reamed, or bored holes meet specified tolerances before parts advance to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in precision machining shops, fabrication facilities, and inspection departments working with small-diameter bores. Class ZZ Plus gages fall within the working gage classification and are commonly used for production-floor inspection of components where a 0.163-inch nominal bore diameter must be confirmed. The single-piece package makes it a straightforward replacement or addition to an existing gage set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.163 inches for small-bore 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 suited to production working gage applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for dimensional stability and long service life\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style working gage for use in standard plug gage handles and holders accepting 0.163-inch diameter gage members.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control inspectors following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion and wear on the measuring surface. Do not force the gage into a bore; damage to the gage member or part can occur if excessive insertion force is applied. Calibrate or verify against a master reference standard at regular intervals per your facility quality plan.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.163 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  \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: 29-163-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700576616754,"sku":"29-163-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc0dcb4b3073a95b3cce253917f1cca3.jpg?v=1788392192","url":"https:\/\/voomisupply.com\/products\/spi-29-163-3-class-zz-plus-plug-gage-0-163-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
