• Dedicated socket for inserting stud bolts (all screws).
• This is an insertion-only socket that eliminates the need for double-nut work when inserting stud bolts.
• Since the stud bolt and the stud bolt setter come into contact at the apex of the steel ball in the back, after the insertion work, the lock is released by turning the stud bolt setter in the loosening direction, and the stud bolt setter can be removed.
