Plug pin gages are precision inspection tools used to verify that a drilled, reamed, or bored hole falls within a specified dimensional tolerance. The minus designation means the gage is manufactured at or below the nominal size, confirming a hole is at minimum at the specified dimension. Machined from steel for dimensional stability, this gage is a standard tool in quality control, production inspection, and toolroom applications.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for production floor inspection and metrology lab use where hole diameter verification is required. It is appropriate for checking through-holes and blind holes in machined parts across metalworking, manufacturing, and precision fabrication environments. Inspectors and machinists use plug gages as a fast, reliable go\/no-go reference when verifying compliance with dimensional drawings and tolerancing standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.373 inches for direct hole inspection at that size\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade suitable for production-level inspection gaging\u003c\/li\u003e\n  \u003cli\u003eMinus designation confirms the gage is ground below nominal, consistent with go-gage function\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for precise dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability in shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-handed 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 in any inspection application requiring hole diameter verification at 0.373 inches nominal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and stored by metrology and quality control personnel, not installed in systems. Clean the gage and the hole being checked before use to avoid false readings from debris or burrs. Store the gage in its protective case when not in use to prevent surface damage that would affect accuracy. Calibration intervals should follow your facility quality management 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: 0.373 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance 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: 19-373-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51706399031602,"sku":"19-373-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b946fd7488f6eb944b47b22be460dc0.jpg?v=1788434171","url":"https:\/\/voomisupply.com\/products\/spi-19-373-0-class-zz-minus-plug-pin-gage-0-373-in","provider":"Voomi Supply","version":"1.0","type":"link"}
