Description
HELICOIL® Plus SCREWLOCK® offers the same thread technological advantages as HELICOIL® Plus free running. In addition, a screw-locking section is worked in, which serves as a screw-locking device. The locking of the screw is achieved by means of one or several polygons formed coils, which grip the threads of the installed screw. In this way an elastically resilient friction lock is created. The locking torque achieved in this way is defined in the standard NASM 8846 for UNC and UNF sizes in accordance to NASM 21209 or can be individually adapted to problem solutions. The red coloured HELICOIL® Plus SCREWLOCK® thread insert, also stamped with the diamond for med embossing, should only be utilised with higher grade screws (starting from 8.8). High grade alloyed screws should be lubricated according to the recommendations of the manufacturer. The same torque should be applied as for the HELICOIL® Plus free running.
