SELF TAPPING SCREWS PHILIPS FULL TRUSS HEAD WITH 18 TEETH FOR SERRATION
Self-tapping screws are mainly used for screwing on metal sheets and laminates through simple drilling, without threading or tapping operations. These screws are not particularly suitable for use on die-cast materials and plastic materials. For a safe and stable screwing, particular attention must be paid to the diameter of the hole to be drilled. A small hole in which the screw "forces" to enter is certainly not synonymous with greater guarantee in fixing. It should also be remembered that the existing tables are empirical and only give an indication of perforation, but they are not a certain rule, as the fixing must be checked from time to time according to the technical-mechanical conditions of the particular that will be tighten.

The underhead knurling has two distinct functions. Once the screw has been tightened, the indentation causes the unscrewing torque used to be greater, making the fixing more stable in all those applications which are subjected to movements and / or vibrations during their use. In the electric field, however, the indentation scrapes the surface of the metal, effectively creating connectivity with the material where grounding is required. However, it must be taken into account that the serration can never replace the tightening of a screw with the serrated washer, which is much more performing in itself.

The large head favors a wider sealing surface as well as the possible covering of through holes in case of sandwich coupling between two sheets, while the low profile and without edges makes them particularly suitable in "visible" applications. This screw has wide fields of application ranging from the mechanical sector to the household appliance, from the auto motive to the aluminum window frame.

The length of the screw is measured from the tip to the underhead.
