11.3mm KonstruX Countersunk Screws fully threaded timber construction screws with a Torx TX50 drive. These screws simultaneously ensure a high extraction resistance and strong joints in timber construction. Also the AG screw tip allows for faster and easier screwing and reduces the effects of splitting. A powerful solution explicitly for construction and renovation.
These construction screws are used during timber frame engineering and a user friendly ECS calculation software package can be downloaded free of charge. The following software allows pre-calculations of main and secondary beam connections, joist doubling and reinforcements of supports. This is also a verifiable calculation aid in accordance with EN 1995 (Eurocode 5) and DIN 1052.

Available 11.3mm KonstruX Screws
One system for all load-bearing connections in timber construction
- For application especially in timber engineering, carpentry, timber frame construction, hall construction, timber element construction, renovation of floor ceilings, etc.
- Also ensures the highest power transmission.
- The fully-threaded screws maximise the load-bearing capacity of a connection due to the high threaded pull-out resistance in both components. When using partial threaded screws, the significantly lower head pull-through resistance in the attachment part limits the load-bearing capacity of the connection.
- They are a time and cost-saving alternative to traditional connections or timber joints such as joist hangers, joist supports, etc.
- Additionally, wood has a low transverse pressure and transverse tensile strength. Hence for reinforcement, the screws are placed in the wood, to “take over” a large part of the forces.
- Doubling up of joists, for example, increases the load-bearing capacity of floor joists and reduces bending. These fully threaded screws subsequently join the components together in a displacement-resistant manner.
- Additionally they have invisible connections, a high fire resistance, and no thermal bridges.
- There is no pre-drilling required after approval/ETA. From screw lengths ≥ 245 mm, however, a trend-setting pre-drilling to 1/3 of the screw length can be recommended (no running of the screw).
- Further in the case of screws that are used exclusively on tension, the required edge and axle distances may be minimised.
