Super Senk Fix
SuperSenkFix head is the innovative combination of a counter-sunk head and a washer head. Enables a flush counter-sinkable head in conjunction with higher pull-through resistance values.
Friction Part
The friction part reduces screwing resistance by opening the hole slightly wider than the screw shank. It is usually combined with the half thread.
Friction Part Geometries
Coarse Thread
Coarse thread allows for up to one third faster install time due to a higher pitch of the thread.
Coarse Thread
Partially Threaded
Partially threaded screws, also known as half thread, pull timber members or steel plates and timber together. For the design head pull-through and withdrawal of thread must be checked. Lateral loads as well as axial loads are efficient transferred.
The axial load capacity of the thread in comparison to the countersunk head is approx. 3:1. Using a washer head screw leads to a similar performance of the thread pull out and the head pull through capacity.
Compactor Tip
The compactor tip reduces the torque resistance by opening the hoe slightly bigger than the core diameter of the screw. This helps to prolong the battery life of the screwdriver for longer machine life and saves time during installation.
