Milling pockets underneath the screw-head for an optimal countersinking:
ideal also for metal fittings
Alternative Head Typ: Washer Head
2 | Friction part
The friction part reduces the in-screw resistance.
3 | Hi-Lo-Thread
According to leading technological standards:
Hi-Lo-Thread for energy saving screwing with improved unscrewing values
Double-start thread for quicker in-screwing times
4 | Tip
Patented compactor tip:
Quicker in its bite at reduced in-screw turning momentum
reduced splitting effect
no pre-drill necessary
Application possibilities of RAPID® Komprex
Beam to columns joint
For this purpose, long partial threaded screws such as the RAPID® Komprex achieve best application results. Due to their double thread, the screwingin can be done in less time compared to other standard products.
Rafters and Rafters-doubling
Partial threaded screws trans-fer the windsuction and shear forces to the substructure via their screw heads. Washer head is recommended.
Doublings as reinforcements are possible on the top or side of the rafters.
