(EN) A FASTENER
(FR) ÉLÉMENT DE FIXATION
Abstract
(EN)
The present application describes a fastener (100) comprising a drive end region (120), a tip end region (106), and at least one screw thread (108) extending from at least proximal the tip end region; and a dowel portion (118) located between the at least one screw thread and the drive end region, said dowel portion comprising a thread form (122) having at least one substantially flat and axially oriented outer surface (126) extending around the dowel portion and at least one channel (124) extending towards the drive end region. A method of manufacturing the fastener is also described.
