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
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.
