Abstract

The screw (100) has a head (10) with a central cavity to accommodate a screwdriver and a rim (12) which may withstand blows from a hammer to drive the conical tip (40) into a piece of wood. The undersurface of the head is conical and there is a plain cylindrical shaft (20) immediately under the head. The threaded portion (30) incorporates first and second helical threads (31,32) with a sawtooth cross-section with the steep slope facing the head.
