with the radius profile of the thread flank.
• Low forming torques and large flank
coverage of the thread.
• High clamping force.
• Large flank coverage of the thread.
• High load-bearing capacity.
• Cold-worked counter thread (nut thread).
• Greater load-bearing capacity.
• Play-free and self-locking seating of the thread.
• Reduces tendency to loosen.
• Prevents loss.
• Formed thread corresponds to a standard
metric thread. The GEFU can also be
®
replaced with a metric screw if necessary.
