KonstruX, countersunk head stainless steel A4

KonstruX fully threaded screw

• High extraction resistance
• Strong joints
• Rust and conditionally acid resistant

One system for all timber-frameconstruction joints 

• Applications in timber engineering and carpentry, timber-frameconstruction, hall construction, construction of timber elements,renovation of ceilings, etc. 
• Maximum load transmissionKonstruX fully threaded screws maximise a joint‘s load-bearing capacitywith a high thread-extraction resistance in both components. If partiallythreaded screws are used, the joint‘s load-bearing capacity is limited bythe considerably lower head pull-through resistance in the attached part. 
• Time savingA time- and cost-saving alternative to traditional connections or timberjoints 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 forreinforcement. The KonstruX “takes on” a large proportion of the forces. 
• Doubling up of joists, for example, increases the load-bearing capacity offloor joists and reduces bending. Here, KonstruX fully threaded screwsjoin the components together in a displacement-resistant manner. 
• Hidden connections, high fire-resistance, no thermal bridges 
• No pilot-drilling required in softwood according to approval/ETA. From screwlengths ≥ 245 mm, however, pilot-drilling to 1/3 of the screw length isadvisable to guide the screw in the right direction (no screw wandering). 
• The required edge and centre distances can be minimised for screws thatare only exposed to tension.
