Description
FUNCTIONING

1) The innovative SIT®20 drive system provides a tight grip and stable engagement, minimising slippage during installation, which reduces wear on both the tool and the screw for consistent, efficient fastening.
2) Designed specifically for hidden clip systems, the thread length ensures the screw fully engages with the clip and substructure, delivering a strong hold while maintaining a clean, seamless surface appearance for decking.
3) The combination of materials in the bi-metal design enables optimal performance when fixing into steel, offering enhanced durability and load-bearing capacity for long-lasting decking installations.
The stainless steel grade of the screws (316) with an additional DELTA® SEAL coat gives them a high corrosion and weather resistance, increased fracture torque, and makes them suitable for outdoor use and close to water applications.
