This gage measures a nominal diameter of 0.047 inches with a tolerance of 0.0002 inches, placing it in the Class ZZ accuracy range suited for general-purpose production inspection. Machinists, toolmakers, and quality control technicians rely on pin gages like this one to confirm bore size conformance during manufacturing and incoming inspection. The minus designation indicates the gage is ground to the lower end of the tolerance band, which is standard practice for plug gages used in go-type applications.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is used in machine shops, fabrication facilities, and quality labs where small-bore dimensional verification is required. At 0.047 inches nominal diameter, it falls in the wire-gage size range and is commonly applied when inspecting drilled or reamed holes in precision components. It is appropriate for use on metals, plastics, and composites wherever tight hole-size control is specified on engineering drawings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.047 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance of 0.0002 inches for general-purpose dimensional verification\u003c\/li\u003e\n  \u003cli\u003eMinus designation grounds the gage to the lower tolerance boundary, standard for go-plug applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability during repeated use\u003c\/li\u003e\n  \u003cli\u003eIndividual unit packaging suitable for single-gage replacement or kit building\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 suitable for use with standard pin gage handles and sets sized for the wire-gage diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages should be inserted and withdrawn by a licensed or trained metrology or machining professional using clean, lubricated technique to avoid galling or scoring the bore being inspected. Always clean and lightly oil the gage before and after use to prevent corrosion and contamination of reference surfaces. Store in a protective case away from other metal tooling to prevent contact damage that can alter the 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: 0.047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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  \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: 19-047-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697418862898,"sku":"19-047-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d845d8d57f24f6a60bf7b54d395e5de.jpg?v=1788351467","url":"https:\/\/voomisupply.com\/products\/spi-19-047-0-class-zz-minus-plug-pin-gage-0-047-in","provider":"Voomi Supply","version":"1.0","type":"link"}
