Most of instances, when the screw isn't able to hold on to the timber joint or any type of various other joint for that matter, it typically implies that the opening has actually been removed. Generally, this issue is created since the timber fibers around the head of the screw have been torn away. Screw joints can hold things together due to just how they are wedged within the fibers of the timber, but if the holes or the fibers in the holes are damaged owing to anxiety, then the fibers will certainly not hold or connect.
