Have you just fitted your flat roof with beautiful roofing, selected the right roof edge trims and are you now looking for a perfect screw to install them? Especially for you, Wovar has the grub screw in its range. This is made of A2 stainless steel stainless steel and is fitted with a 15 mm EPDM washer so that the aluminium is not in contact with the screw itself and it is sealed Waterproof. This is to prevent any corrosion from occurring.

Matches of the Wovar mortise screw

You can recognise the Wovar mortise screw by its lens 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. 

Mounting the pencil screw

Before installing these screws in the aluminium roof edge trims or profiles, pre-drill for optimal fastening. For the 4.5 mm thick dowel screws you should pre-drill with a 4 mm metal drill bit, which you can find in the metal drill bits category.

What length screws should I use 

To determine the correct length of the screws for mounting, take the thickness of the profile you want to mount and add at least 2 cm for fastening in the wood. This is because it is important that the mortise screws are screwed at least 2 cm into the wood. This ensures powerful fastening of your profiles. So with these 4.5 x 35 mm screws you can install roof edge trims with a maximum thickness of 15 mm.
