Facade screws

EJOT offers various SUPER-SAPHIR self-drilling screws to form floating and fixed points in rear-ventilated facades. They perfectly fasten pre-drilled stainless steel or aluminium wall brackets to aluminium support profiles. These facade screws are made of A4 stainless steel and feature a hardened steel drill point. A buffer zone between the screw head and the sliding disc prevents excessive clamp load of the joint.
