The Force Attack Cross Head Z is a further development of the simple cross-force attack by the company Philips SCREW COMPANY. The difference is that the four edges of the screwdriver blade do not taper toward the tip. This increases the lateral hold for the bit and reduces the cam-out effect. This is the result of conventional cross-head power attacks by rejuvenation, because the torque of the cordless screwdriver pushes the screwdriver bit upwards.
Properties such as head pull resistance or contact pressure are also required in furniture construction. Our universal screw with backplane head offers both to fix the hardboard back panel to the rear of furniture corpus. The flat shape does not add to it and the contact surface on the fiber plate is enlarged. The head offers high support and can be released if the body is disassembled and re-usable later.
In contrast to the partial thread, the full thread extends over the entire length of the screw. The more threads a screw has, the greater the tensile and compressive forces that can be deflected from screw to wood via it. Our threaded screws are used mainly for high-strength wood joints.
The term 4CUT stands for the square shape of the screw tip. These edges supplant the wooden fibers during insertion and creates space for the core diameter of the screw. This reduces the spread pressure exerted by the Kern in the wood and prevents the wood from springing up close to the edges. The necessary torque of the cordless screwdriver is also reduced, because the Kern of the screw does not have to "squeeze" itself into the wood.
With WIROX, SPAX has developed a coating that is far superior to zinc plating in terms of corrosion protection. With WIROX no chrome (VI) is used, the screws can be loaded just as well after years in the not directly weathered external area as well as environmentally friendly. WIROX screws are the first choice for all open buildings without direct weathering such as carports or pergoles, for direct weather stresses as with terraces we recommend our screws in the stainless steel version.
