Use them to bolt two 1-2-3 blocks together. Use them to reduce the hole in 7/16" or 1/2" T-slot nuts to 1/4"-20 thread.
These inserts use Loctite® adhesive to keep them in place. The adhesive reaches full strength after 72 hours.
Set the insert with a bolt and two nuts, or use a slotted screwdriver.
