With a bilateral tolerance of 0.0002 inches, this gage meets Class ZZ Plus accuracy standards, making it suitable for quality control applications in manufacturing, machining, and toolroom environments. The steel construction provides durability through repeated use cycles. Machinists, quality technicians, and tool room personnel use this type of gage to verify that drilled, reamed, or otherwise finished holes fall within specified dimensional limits.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production inspection and incoming quality control settings where small-diameter hole verification is required. It is well suited for checking holes produced by drilling, reaming, or EDM processes in metalworking and precision fabrication shops. The 0.142-inch nominal size targets a common drill size range used in ferrous and non-ferrous part production. Weighing 0.2 pounds, the gage is compact and easy to handle at the point of inspection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus accuracy with 0.0002 inch tolerance for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eNominal measurement diameter of 0.142 inches for small-bore applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance during repeated gauging cycles\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, suitable for bench or in-process use\u003c\/li\u003e\n  \u003cli\u003eIndividual unit packaging — sold as single gage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard inspection tool for go\/no-go plug gage sets requiring a 0.142-inch Class ZZ Plus member.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are used by quality technicians and machinists and require no special installation. Before use, clean the gage and the bore being inspected to remove chips, coolant, and debris that could affect measurement accuracy. Handle with care to avoid dropping, as impact can alter gage geometry and invalidate its calibration. Periodic recalibration against a traceable standard is recommended per your facility quality management procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.142 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 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: 29-142-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51708882059570,"sku":"29-142-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a297c1133bdec93502c513f7ec08b4e.jpg?v=1788448860","url":"https:\/\/voomisupply.com\/products\/spi-29-142-7-class-zz-plus-plug-gage-0-142-in","provider":"Voomi Supply","version":"1.0","type":"link"}
