SPEED AND PRECISION
Quick fastening without pre-bored holes, with the possibility of simultaneous drilling of 1 to 3 steel plates.

RIGIDITY AND DUCTILITY
Very rigid joint system, thanks to the lack of play between the hole and dowel.

OPTIMISED GEOMETRY
Self-perforating wood-steel tip, cylindrical hidden head, underhead thread to make insertion easier and impede slippage.

FIELDS OF USE
Self-perforating system for wood-steel retractable junctions. Can be used with S235/St37/Fe360 steel with a maximum thickness of 10 mm (1 plate) or 5 mm (2 and 3 plates). Can be used with screwdrivers with 1500 rpm minimum. Service classes 1 and 2.

RIGID JOINTS
The connectors allow for the creation of rigid joints able to transfer bending moment stresses (moment-resisting joints). The reduced diameter also guarantees excellent ductility, ideal for anti-earthquake designs.

PROTECTED RETRACTABLE JUNCTIONS
The connectors allow for the rapid and precise execution of retractable junctions on steel or aluminium alloy brackets (ALU brackets). The reduced dimensions allow for excellent fire protection.

INTERLOCKING JOINTS
The reduced diameter of the connector (7mm) and the rapid installation without pre-bored holes makes this system excellent for the creation of interlocking joints on one or more steel plates (e.g. X10 pillar bases).

APPLICATIONS

• Rigid ”knee“ joint with double internal plate;
• ALU bracket fastening (without holes) for shear joint;
• Fastening of pillar base with internal plate for shear joints.
