Our 04364 terrace screws stand out for a variety of characteristics. Their cylinder trim-head is meant to be sealed into the wood and ensures maximum grip and a perfect aesthetics. The inverted under-head thread pushes the wood particles down during drilling, guaranteeing a clean finish, while the trilobular thread is ideal for hardwood surfaces, providing three contact points instead of one. The special saw-toothed type 17 point accelerates the drilling and reduces the danger of splitting the wood. Soon also available with flat head (05364), the terrace screws don’t need pre drilling. Their stainless steel versions (04367 and 05367), however, do. The special 1000 Hr three-layered Nano coating ensures extremely high resistance against rust and weather damages.
