JBO Thread Plug Gauge - Metric Coarse Go/No-Go - Left Hand - 6G - M20 x 2.5 Face Mill Arbors stable cutting: Improves chip evacuationThe JBO Thread Plug Gauge is a precision tool designed to verify metric coarse holes against the M20 x 2. 5 standard. In left hand configurations, it helps machinists, inspectors, and maintenance teams quickly confirm correct threading before assembly or repair work. Go No Go inspection design: Quickly verify that a threaded hole meets the M20 x 2. 5 coarse thread specification; the go end should pass, while the no go end remains outside tolerance,
