Bi-metal self-drilling fastener is engineered for securing pre-drilled stainless steel or aluminium wall brackets to aluminium support profiles, featuring a buffer zone that limits clamp load, prevents stick-slip, and provides visual set control.

The captive sliding washer ensures consistent low contact pressure, while the fine-pitch thread delivers high tensile and transverse load transfer without thread stripping in the secondary component. Designed for both floating and fixed point assemblies, it incorporates a case-hardened carbon steel drill point, 5.0 mm diameter, 3.00 mm drilling capacity, and an 8 mm clip-hex drive, manufactured in A4 stainless steel for durability and corrosion resistance.

Features and benefits:

• Buffer zone between the screw head and sliding disk prevents excessive clamp load of the joint.
• Pre-assembled captive sliding washer.
• Consistently low contact pressure prevents stick-slip phenmenon.
• No stripping/destruction of the thread in component II resulting in high tensile load capacity.
• High tensile and transverse load transmission in component II due to fine pitch thread.
• Buffer zone serves as visual set control.
• Same assembly concept for floating and fixed points.
