Go - Not Go:
THREAD PLUG "NO GO"
The "No Go" side controls the initial thread of the insert. In order to verify its correct placement, the "No Go" side must not thread more than two times (without using additional force).
THREAD PLUG "GO"
The "Go" side controls the insert threading from the beginning to the end. In order to verify its correct placement, the "Go" side must thread easily down the insert (without using additional force).

Control plug gauges are used on all types of thread inserts.
Control plug gauges available by request for UNC, UNF, BSP, BSW and BSF threads.
