BIG-SERT® is a heavy wall solid bushing, easy to install with positive placement.

 

BIG-SERT® gives increased load protection for critical use.

 

BIG-SERT® will repair oversize holes which have previously been repaired.

 

NOTE: Bottom few internal threads are incomplete.

The insert driver (Roll form tap) seats the insert and completes the bottom threads.

This pushes the pin out to contact the threaded hole. Back out of the insert is prevented by the cam lock effect of the pin.
