Characteristics of mortise screws

The mortise screw can be recognised by its lens-shaped head (also called lens head), this head shape has the advantage of a much nicer finish and an elegant shine. Furthermore, the screw has a Partial Thread which has the advantage that the profile tightens during assembly and is well secured. The drive is a TX-20 making it easy to tighten. 

Always pre-drill first

To install these screws in the aluminium roof edge trims or profiles, pre-drill first for optimal fastening. For the 4.5 mm thick spider screws you should pre-drill with a 4 mm metal drill bit, which you can find in the metal drill bits category. For mortise screws, this means that they should be secured at least 2 cm into the wood. This is why you should buy screws that are at least 2 cm longer than the thickness of the profile or roof edge trim you want to secure. Wovar screws are naturally of the best Quality and always inexpensive.
