ABSTRACT:
A metal guide member (1) for guiding a fastening member (12) into a hard receiving material, as it is driven by an explosive powder charge driven setting tool, has a through opening (2) with a guide arrangement formed of at least three spaced-apart, plastically deformable guidance surfaces with such surfaces having a convex shape extending in the axial direction of the through opening. The guide arrangement assures guidance of the fastening member as it is driven and, at the same time, avoids any interference with the deformation of the guidance surfaces.
