Full-Torque Flush Through (FFT)

FFT style inserts are the most popular and easy to install. They finish flush to the surface when installed.
 

Full-Torque Flush Blind (FFB)

FFB inserts can be used to seal a bolt hole. It is now easy to change a through hole to a blind hole or to seal a cracked hole permanently and easily.
 

Full-Torque Shoulder Through (FST)

The shoulder at the top of the insert adds additional hoop strength around the threaded hole for better resistance to side loading.
 

Full-Torque Shoulder Blind (FSB)

Bolt holes that connect to the water jacket must be sealed to prevent coolant leaks. FFB inserts offer the most strength to the repair site while sealing the hole.
