At 0.355 inches in diameter, this pin gage is manufactured to a minus tolerance of 0.0002 inches, meaning the actual pin diameter is held below the nominal dimension within that allowable deviation. Plug pin gages are go\/no-go measurement tools used in precision inspection work across machining, fabrication, and quality control environments. Licensed machinists, toolmakers, and quality technicians are the primary users of this type of gage.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspection of drilled, reamed, or bored holes in metal, plastic, or composite workpieces where tight dimensional control is required. Class ZZ is the commercial-grade tolerance class for plug gages, appropriate for general inspection applications where extreme gage accuracy is not required. The minus designation means the gage is used to check that a hole is at or above the minimum allowable diameter, making it the go gage in a standard go\/no-go pair. It is commonly used on production floors and in job shops handling close-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance class for commercial-grade go-gage inspection\u003c\/li\u003e\n  \u003cli\u003e0.355-inch nominal diameter with 0.0002-inch minus tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production inspection environments\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual replacement or kit supplementation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a go-style pin gage for use in standard plug gage handles and holders sized for 0.355-inch diameter pins, consistent with common commercial pin gage set systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages should be handled with clean, dry gloves or a gage cloth to prevent corrosion from skin oils. Insert the pin into the bore with light, even hand pressure only — do not force the pin or use tools to drive it. Store the gage in a protective case away from temperature extremes to maintain calibration integrity. Periodic recalibration against a certified master reference is recommended per applicable quality system requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.355 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (minus)\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\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: 19-355-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51719381647666,"sku":"19-355-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d5074ccdf052e3cbd377e3fe9a74c08.jpg?v=1788559150","url":"https:\/\/voomisupply.com\/products\/spi-19-355-7-class-zz-minus-plug-pin-gage-0-355-in","provider":"Voomi Supply","version":"1.0","type":"link"}
