KonstruX fully threaded screw 

  • High extraction resistance
  • Strong joints

Benefits of NEW drill point 

  • Reduced screwing torque
  • Greater extraction resistance

One system for all timber-frame construction joints 

  • Applications in timber engineering and carpentry, timber-frame construction, hall construction, construction of timber elements, renovation of ceilings, etc.
  • Maximum load transmission KonstruX fully threaded screws maximize a joint‘s load-bearing capacity with a high thread-extraction resistance in both components. If partially threaded screws are used, the joint‘s load-bearing capacity is limited by the considerably lower head pull-through resistance in the attached part.
  • Time saving A time- and cost-saving alternative to traditional connections or timber joints such as joist hangers, joist supports, etc.
  • Timber has a low transverse compressive and shear strength. KonstruX fully threaded screws are inserted into the timber forrein forcement. The KonstruX “takes on” a large proportion of the forces.
  • Doubling up of joists, for example, increases the load-bearing capacity of floor joists and reduces bending. Here, KonstruX fully threaded screws join the components together in a displacement-resistant manner.
  • Hidden connections, high fire-resistance, no thermal bridges
  • No pilot-drilling required in accordance with approval/ETA From screw lengths ≥ 245 mm, however, pilot-drilling to 1/3 of the screw length is advisable to guide the screw in the right direction (no screw wandering).
  • The required edge and center distances can be minimized for screws that are only exposed to tension.
