The Angle-bracket screw (ABS) Strong is made of hardened carbon steel that has been specially designed for joints involving steel plates. The special screw geometry reduces the splitting effect produced during the screw’s installation and, combined with the self-clearing groove, ensures that the screw „bites“ quickly. The screw’s increased shank diameter creates higher shear forces between the steel plate and the wood. The screw’s special geometry directly beneath the head ensures an excellent static performance that results from a plug-in effect between the screw and plate. In addition, the screw head’s edgeless geometry minimises the number of stress concentration points while enhancing the screw’s structural strength.
