摘要

A rail with points and end head is used as a spreader for plastic dowels for fastening into walls items with inner bore such as hooks, brackets, etc.. The stem of the nail has at least one longitudinal edge in its cross-section; the head has a cross-section to fit into a matching recess in a tool which is used to drive it in. ADVANTAGE - The rail for use as the spreader in a plastic dowel can also serve to make the hole in a wall for a fixing device. In the example shown, the nail is pointed at one end (1) and has a head (3) which fits into a matching recess (4) on a hammering tool (5). The fit is improved by a cylindrical top end (6) or the head which enters the bore (7) on the tool (5). This tool (5) is suitably mounted and hammered into the wall while the nail is fitted on.
