Benefits of NEW drill point 
• Reduced screwing torque 
• Greater extraction resistance

KonstruX fully threaded screw 
The powerful solution for construction and renovation

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 maximise 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 for reinforcement. 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 centre distances can be minimised for screws that are only exposed to tension.
ECS calculation program for KonstruX 
This user-friendly software allows pre-calculation of main–secondary beam connections, joist doubling and reinforcements of supports. Verifiable calculation aid in accordance with EN 1995 (Eurocode 5) and DIN 1052. i
