With a measurement diameter of 0.019 inches and a tolerance of 0.0002 inches, this gage is built for applications where tight dimensional control is required. Constructed from steel, it delivers the durability and wear resistance expected in production toolroom and quality-control settings. Machinists, toolmakers, and metrology technicians use plug gages like this to confirm that drilled, reamed, or punched holes fall within specified limits before parts advance to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in precision machining shops, toolrooms, and inspection departments working with small-diameter holes. The 0.019-inch nominal diameter places it in the micro-diameter range, making it appropriate for delicate workpieces, watch components, instrument parts, and similar fine-tolerance assemblies. It is a go or no-go style reference tool used during in-process inspection or final part acceptance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement diameter: 0.019 inches for micro-diameter hole inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance: 0.0002 inches, meeting Class ZZ Plus accuracy requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact, single-unit packaging suitable for individual toolroom use\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus rating appropriate for production and general inspection gaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard plug gage for verifying 0.019-inch nominal diameter holes in steel, aluminum, and similar workpiece materials across precision machining and inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, toolmakers, and quality technicians. Clean the gage and the workpiece bore before use to prevent debris from causing false readings or premature wear. Store the gage in a protective case away from other tooling to avoid surface damage. Do not force the gage into a hole; if resistance is encountered, the hole is undersize and should be reworked before re-inspection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.019 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: ZZ Plus\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: 29-019-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51709402906930,"sku":"29-019-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d42dce9090b8cc6af4d06b59aa6abe7.jpg?v=1788455904","url":"https:\/\/voomisupply.com\/products\/spi-29-019-7-class-zz-plus-plug-gage-0-019-in","provider":"Voomi Supply","version":"1.0","type":"link"}
