The triple thread point ensures that the screw quickly grips the wood and is powerfully screwed in. The specially shaped milling ribs under the head smoothly sink into the wood and stop on metal without damaging the surface.
The 4Top coating is a new protective coating for Hapax screws that consists of several layers: an organic coating is applied to the basic galvanizing layer in several coatings totaling at least 15µm, guaranteeing very good corrosion protection. This coating can be used for applications in corrosion class C4 according to ISO 12944-2*. This makes the Hapax wood screw with 4Top coating perfect for outdoor environments.
The professional wood construction screw from HAPAX with 4Top coating is available in various sizes. The "triple thread point" ensures that the screw both grips quickly and screws powerfully into the wood. Which makes the screw suitable for use in fastening applications. The specially shaped milling ribs under the head countersink, into the wood and stop on metal without damaging the surface.
