Built to Class ZZ tolerance standards, this gage carries a tolerance of 0.0002 inches, making it appropriate for general-purpose inspection work where tighter gage grades are not required. Constructed from steel for durability and wear resistance, it is a straightforward, single-piece inspection tool used by machinists, quality control technicians, and toolroom personnel to verify bore size conformance during production or incoming inspection.\u003c\/p\u003e\u003cp\u003eThis plug gage is suited for use in machine shops, manufacturing facilities, and toolrooms where hole diameter verification is part of a standard quality assurance process. It fits applications requiring inspection of drilled, reamed, or bored holes at the 0.164-inch nominal diameter. The Class ZZ Plus designation indicates a commercial-grade gage appropriate for checking parts where tolerance requirements are moderate rather than precision or master-grade.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNominal measurement diameter of 0.164 inches for precise bore inspection\u003c\/li\u003e\n\u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for general-purpose go\/no-go inspection\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability and resistance to wear during repeated use\u003c\/li\u003e\n\u003cli\u003eCompact single-piece format for straightforward handling in production or toolroom environments\u003c\/li\u003e\n\u003cli\u003ePackaged individually for direct deployment to inspection stations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose go\/no-go plug gage for inspecting cylindrical bores with a nominal diameter of 0.164 inches in machined components across standard manufacturing and toolroom applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are handled and used by quality control technicians and machinists rather than installed in a system. Clean the bore and gage contact surfaces before use to prevent false readings caused by chips, coolant, or debris. Store the gage in its protective case when not in use to prevent damage to the precision-ground surfaces. Calibration and periodic inspection against master references should follow ASME B89 standards or the applicable shop metrology program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.164 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\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: 29-164-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692635816242,"sku":"29-164-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7938f0ba13c605129eb3b2ff789fa48a.jpg?v=1788300376","url":"https:\/\/voomisupply.com\/products\/spi-29-164-1-class-zz-plus-plug-gage-0-164-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
