A balcony is a load-bearing structure in which the timber is partly exposed to direct and indirect weathering. Nevertheless, A2 stainless steel SPAX are the first choice here. With countersunk head and partial or full thread, raised countersunk head or pan head. SPAX with a washer head and diameter of 6 or 8 mm – also in A2 stainless steel – are also available. The washer head guarantees higher tightening torques, so that joints can be tightened better even when the timber is warped.
