Plug pin gages are used to verify hole diameters by go\/no-go inspection — confirming whether a drilled, reamed, or punched hole falls within an acceptable size range. The Class ZZ designation identifies this as a working gage suited for production floor inspection rather than laboratory-grade calibration. Constructed from steel, this gage is a standard tool for machinists, quality control technicians, and tool and die professionals working to close-tolerance specifications.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is used in manufacturing and machine shop environments where precise hole verification is required. It is appropriate for inspecting small-diameter holes in metal, plastic, or composite workpieces. The minus tolerance designation means the gage diameter is ground to the lower limit of the nominal size, consistent with standard minus gage conventions for go-side inspection work. It suits applications in general metalworking, aerospace component inspection, automotive parts production, and precision fabrication wherever 0.052-inch hole conformance must be confirmed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.052 inches for small-hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance class — standard working gage for production inspection\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance ground to 0.0002 inches for lower-limit go-side verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability on the production floor\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suited for individual technician use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for use with pin gage handle sets and gage blocks compatible with 0.052-inch diameter working gages in general production inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are handled and used by quality control technicians and machinists; avoid touching the gage surface with bare hands to prevent corrosion from skin oils. Store in a protective case or gage block organizer when not in use. Clean and lightly oil the gage after each use to maintain surface integrity and measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (Decimal Inch)\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: Class ZZ Minus\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: 19-052-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699953434930,"sku":"19-052-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93f95032691b5b99d7a70d6d9bd256a1.jpg?v=1788383984","url":"https:\/\/voomisupply.com\/products\/spi-19-052-0-class-zz-minus-plug-pin-gage-0-052-in","provider":"Voomi Supply","version":"1.0","type":"link"}
