Structural wood screws for outdoors and aggressive environments: choose the best, choose HBS EVO.
The special 20 μm multilayer C4 EVO coating with surface treatment of epoxy resin and aluminium flakes makes HBS EVO the perfect screw for application outdoors and in aggressive environments. It is approved for structural applications subject to stresses in any direction vs. the grain (α = 0° - 90°).
Asymmetric “umbrella” threading for excellent wood pull-through. HBS EVO is characterised by superior strength: the tests performed have shown that the steel has excellent failure and yield strength (fy,k = 1000 N/mm2) and very high torsional strength (ftor,k) for safer screwing. Certified for use in service class 3 outdoor applications and under class C4 atmospheric corrosion conditions.
Excellent for fastening framed panels and lattice beams (rafters, trusses), it offers superb performance in fastening on solid timber and glulam, CLT, LVL and high-density woods.
HBS EVO values are tested, certified and calculated for high-density woods.
