Structural screws for outdoors: discover TBS EVO, the flange-head wood screw.
TBS EVO is approved for structural applications subject to stresses in any direction vs. the grain (α = 0° - 90°).
Its flange head makes it ideal in the presence of wind or variations in timber dimensions. The asymmetric “umbrella” threading ensures better wood pull-through.
Excellent for the construction of outdoor structures such as walkways and arcades and for fastening SIP and sandwich panels. In combination with the WBAZ gasket washer, it is suitable also for fastening on sheet metal up to 0.7 mm thick, with no need for pre-drilling.
TBS EVO wood screws are usable with wood-based panels, solid timber and glulam, CLT and LVL, high-density woods, aggressive woods containing tannin and chemically treated woods.
Made of carbon steel and thanks to the 20 μm multilayer coating with surface treatment of epoxy resin and aluminium flakes, it is perfect in applications with woods containing tannin or treated with impregnating agents or other chemical processes.
Tests have shown no rust after 1440 hours of salt spray exposure, according to ISO 9227.
Can be used in service class 3 outdoor applications and under class C4 atmospheric corrosion conditions.
Values are also certified for inserting the screw parallel to the grain.
