Turnbuckle screw stainless steel A2 - 4.5 x 60 mm - Box 200 pieces

Fixing your roof edge trims and other aluminium profiles is of course done with strong sealants or the right screw. We prefer the (Classic) solution of a screw as sealants can come loose over time. With a good screw, the roof edge trims or Aluminium are permanently fixed.

There is a special screw for this at Wovar, namely the grub screw that we have in our range. This is a lens head screw made of A2 stainless steel Quality that is provided with a 15 mm EPDM washer to protect the Aluminium from corrosion of the screw itself and to seal the screw hole completely Waterproof.

What is a grub screw?

You can recognise the Wovar grub 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 Partial Thread which has the advantage that the profile tightens during assembly and is well secured. The drive is a TX-20 which makes it easy to tighten. 

Drill like this

Before installing these screws in the aluminium roof edge trims or profiles, pre-drill for optimal fastening. For the 4.5 mm thick grub screws you should pre-drill with a 4 mm metal drill bit, which you can find in the metal drill bits category. For the spider screws, it is important that they are screwed at least 2 cm deep into the wood to ensure a strong fastening of your profiles. With these 4.5 x 60 mm screws, you can therefore secure up to 40 mm thick aluminium profiles and other steel in the wood.
