GEFU®-SCREWS with TAPTITE 2000® thread
GEFU® SCREWS with TAPTITE 2000® thread are designed so that the advantages of the previous TAPTITE screws are combined with a new thread shape - a thread with a radius profile.
The result is a thread-rolling screw that has exceptional mechanical, connection and ergonomic characteristics which are not surpassed by any other technology.
This radius profile facilitates the flowing of the nut material towards the screw thread core.
The TAPTITE 2000® thread reduces the tapping torque by up to 50 percent in comparison with conventional thread-rolling screws as per DIN 7500.
Furthermore, the use of GEFU® TAPTITE 2000® increases the reliability of the screw fitting process and generates higher pretensioning forces.
THE "15/85" PRINCIPLE
Using thread-rolling screws reduces incidental costs by up to approx. 85% for thread-cutting, controls, tools, etc. Approx. 15% remains for the fastener itself, i.e. the cost of the screw.
The thread of thread-rolling screws is designed so that the shaped inner thread can take a screw with metric ISO threads (standard thread) with a tolerance of 6 h. The shape and the arrangement of the rolling area of the thread are determined according to purpose.
