JBO Thread Plug Gauge - Metric Fine Go/No-Go - Right Hand - 5H - M3.5 x 0.25 Endmill25 and ISO H4 tolerance—made toThe JBO Thread Plug Gauge is a precision tool for testing metric fine threaded holes. Designed for engineers, machinists, quality inspectors, and assembly teams, it verifies that a hole meets the M3. 5 x 0. 25 fine pitch standard with a simple Go No Go check and a right hand orientation that matches common production threads. The dual ended design lets you quickly pass or fail a hole, helping prevent misfits and rework in manufacturing and assembly
