Pin gages in this class are used to verify hole diameters, slot widths, and feature locations to tight dimensional standards. The minus designation means the gage is ground to the low side of the nominal size, ensuring a go-condition check without risk of overstating the actual hole dimension. Constructed from steel, this gage holds up to routine shop-floor use. It is a standard single-pin tool suited for quality control, inspection, and setup verification tasks in precision manufacturing and machining environments.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are a general-purpose inspection grade commonly used in production and inspection departments where working-grade accuracy is required. This 0.673-inch gage is appropriate for checking bored holes, drilled features, and machined slots in metal, plastic, and composite workpieces. Machinists, tool and die makers, and quality technicians use gages like this during in-process and final inspection to confirm hole acceptance before parts move to assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.673 inches with a minus tolerance of 0.000200 inches for accurate go-side verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ designation — general-purpose working grade suitable for production inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated shop-floor use\u003c\/li\u003e\n  \u003cli\u003eSingle-pin format for straightforward hand-held hole checking\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy one-handed operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage for use with standard hole inspection applications requiring a 0.673-inch nominal diameter check.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages require no installation but should be handled and stored with care to prevent damage to the ground surfaces. Clean and degrease the gage and the feature being checked before use to ensure accurate readings. Do not force the gage into a hole — apply only light hand pressure to avoid deflecting the pin or damaging the workpiece. Store in a protective case away from other tooling to prevent nicking or scratching the precision ground diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.673 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.000200 inches (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: 19-673-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698275418418,"sku":"19-673-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0f02dba204e70110657c614c0943d2c.jpg?v=1788360350","url":"https:\/\/voomisupply.com\/products\/spi-19-673-3-class-zz-minus-plug-pin-gage-0-673-in","provider":"Voomi Supply","version":"1.0","type":"link"}
