ARNOLD UMFORMTECHNIK
With the use of the LocTec® - safety drive reduce you the expenditure and the costs with the production of safety screw connections substantially, without being received thereby qualitative compromises. Any turning off attempt, even with the safety device bit used for the assembly, ends with the independent unscrews the assembly tool. Thus a loosening of the connection becomes possible only by mechanical treatment of the screw head.
