Longer length (60%) asymmetric ”umbrella“ thread.
Highly ductile (moves with the wood) and resistant steel (fy,k = 1000 N/mm2)
Guarantees an excellent surface finish and the possibility of usage on steel plates with circular holes.
Surface treatment with high corrosion resistance, comparable to class C5.
FIELDS OF USE
Exterior use; appropriate for service classes 1-2-3.
The pan head with flat under head compresses the fibres at the end of the joint, guaranteeing a perfect aesthetic finish.
The special high resistance steel guarantees the possibility of safe joints with high static performance under all service conditions (service classes 1-2-3).
STEEL – WOOD
Ideal for use on steel plates with circular holes and hence for exterior fastening systems in service class 3 (pillar bases).
