When you have purchased aluminium profiles, you will of course need to install them on your roof, facade or deck.

This is a lens head screw made of A2 Stainless steel Quality that is fitted with a 15 mm EPDM washer to protect the Aluminium from corrosion of the screw itself and to seal the screw hole completely Waterproof.

Recognition of the spider screw

You can recognise the Wovar spider screw by its lens head (also called lens head), this head shape has the advantage that the finish is much more beautiful and has 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. 

Is pre-drilling necessary for spanner screws?

Before installing these screws in the aluminium roof edge trims or profiles, pre-drill 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 category metal drill bits.

Determine screw length

To determine the correct length of the screws for mounting, take the thickness of the profile you want to fix and add at least 2 cm for fixing in wood. This is because it is important that the spider screws are screwed at least 2 cm into the wood. This ensures powerful fastening of your profiles. With these 4.5 x 50 mm screws you can mount all kinds of aluminium profiles with a maximum thickness of 30 mm.
