JBO Thread Plug Gauge - Metric Coarse Go/No-Go - Right Hand - 4H - M5 x 0.8 Face Mill Arbors - Through Coolant and hobbyists needing accurate boreThe JBO Thread Plug Gauge is a precision tool designed for metric coarse threads. Sized for M5 x 0. 8 with right hand orientation and 4H tolerance, it uses a go no go design to quickly verify threaded holes and ensure proper fitment of components in manufacturing and assembly tasks. Go No Go quick checks: The two end design lets you rapidly confirm whether a threaded hole meets the M5 x 0. 8 specification, speeding inspections and reducing guesswork.
