BIG-SERT ® PROFESSIONAL THREAD REPAIR KITS OVERSIZED HOLES
BIG-SERT® OVERSIZED THREAD REPAIR KITS AND INSERTS
Used for threads which have been previously repaired and failed.
These kits will repair holes that were repaired by helicoil, perma-coil,
uni-coil, recoil or any other similar coil style insert that failed.
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 install driver seats the insert and completes the bottom internal threads locking the insert in place.
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.
