Turbo Trallskruv A4 Stainless Steel

Turbo Trallskruv Syrafast A4 is made of acid-proof steel to handle the toughest stresses in the toughest environments and is therefore recommended eg. when screwing bridges and hardwoods.

Sharp tip and threads adapted for anchoring in wood. The threads gripped immediately and pull the screw in the trolley, while the grooves underneath the head lower the screw. Suitable for mounting of trusses, balconies, fences etc. The unique characteristic of the screw has been achieved by providing the screw with a cutting drill tip, as well as oblique and longitudinal intersections between the threads. This provides the following properties:

• Less risk of cracks in wood
• Lower torque when tightening
• Less screwing time
