Terrace screw for aluminium construction 5,5 mm, stainless steel C1

The stainless steel screw is specially designed for firm and fast anchoring of the patio slabs to the aluminium substructure. It is a professional solution for mounting wooden terraces on aluminium profiles.

Thanks to its unique geometry with special wings, the screw can pre-drill the wood without the need for pre-drilling and at the same time creates a thread in the aluminium profile by itself. This significantly speeds up assembly and reduces the risk of damage to the material.

Main advantages

• Installation without pre-drilling - saving time on site
• Special wings enlarge the hole in the wood and eliminate tension
• Self-tapping thread formation in aluminium
• TORX drive (TX20) for precise and secure screwdriving without "slipping"
• Reduced risk of wood cracking due to optimized geometry
• Suitable for both professional and serial patio installations

Material and durability

The screw is made of hardened stainless steel (martensitic steel according to DIN EN 10088), which ensures high strength and long-term durability in outdoor environments.
