Measuring 0.144 inches in diameter with a tolerance of 0.0002 inches, this gage delivers the accuracy required for quality control on machined components and assemblies. Constructed from steel for durability and dimensional stability, the 29-144-3 is a standard tool in machine shops, manufacturing facilities, and precision-assembly environments. Metrology technicians and machinists use it to verify that drilled, reamed, or punched holes fall within specified tolerances before parts advance through production.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for applications requiring fine-tolerance hole verification in manufacturing and inspection settings. Its small 0.144-inch diameter makes it appropriate for checking tight-clearance holes in precision components such as fastener holes, pin locations, and similar features. Class ZZ Plus designation indicates it meets the tolerance class specified for workshop-grade go\/no-go gages, making it a reliable choice for production floor inspection as well as incoming quality checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.144-inch measurement diameter for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance conforming to Class ZZ Plus standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual workstation use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition to standard plug gage sets for go\/no-go inspection of 0.144-inch nominal diameter holes in general manufacturing and quality-control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by metrology technicians and machinists — no power tools or energy sources require lockout before use. Keep the gage clean and lightly oiled when stored to prevent corrosion on steel surfaces. Never force the gage into a hole; apply light, consistent hand pressure only to avoid damaging the gage or the workpiece. Periodic recalibration against traceable standards is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.144 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 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  \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: 29-144-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714496463154,"sku":"29-144-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a683858ab295dcf7c051c3df64269180.jpg?v=1788502302","url":"https:\/\/voomisupply.com\/products\/spi-29-144-3-class-zz-plus-plug-gage-0-144-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
