This gage measures a nominal diameter of 0.446 inches and is manufactured from steel for durability and dimensional stability. It carries a tolerance of 0.0002 inches, which meets Class ZZ specifications for go\/no-go gauging in production and quality control environments. Machinists, toolmakers, and quality technicians use plug pin gages like this one to confirm that drilled, reamed, or bored holes fall within acceptable tolerance ranges before parts advance in the production process.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for use in machine shops, manufacturing facilities, and inspection departments where precise hole verification is required. The minus designation indicates the gage is ground to the lower boundary of the nominal diameter, making it appropriate for checking minimum material condition in standard go\/no-go setups. It is a straightforward hand-measurement tool that integrates into conventional gage block and pin gage set workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.446 inch nominal diameter for direct hole verification at that dimension\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance of 0.0002 inches for production-grade accuracy\u003c\/li\u003e\n  \u003cli\u003eMinus designation confirms minimum material condition boundary gauging\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact single-pin format compatible with standard pin gage handles and sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or supplemental pin for standard Class ZZ plug pin gage sets requiring a 0.446 inch minus member.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are hand-measurement instruments installed by machinists or quality technicians without special tools. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not force the pin into an undersized hole, as this can damage the gage or the workpiece. Store separately or in a designated gage holder to avoid contact damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.446 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 (mm)\u003c\/strong\u003e: 0.0002 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 19-446-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698081071410,"sku":"19-446-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/665360ea9600ac1976bf3b16d03af0fb.jpg?v=1788357461","url":"https:\/\/voomisupply.com\/products\/spi-19-446-4-class-zz-minus-plug-pin-gage-0-446-in","provider":"Voomi Supply","version":"1.0","type":"link"}
