The FDS® flow drill screw manufactured by and available from Semblex Corporation, Elmhurst, IL, USA, was developed as an innovative single-sided fastening solution that is ideal for assembly into extruded and hydroformed profiles and difficult-to-reach locations. The FDS flow drill screw fastener product brings together the technology behind flow drilling and thread forming screws into a single process. The combination of speed and end load allow the fastener to not only penetrate unprepared layers, but to also maximize thread engagement  through the creation of deep extrusions.
