ROOF COVERING, ROOF SLATE TILE AND HOOK-LIKE FASTENING BOLT THEREFOR

摘要

The other pin with its downwardly bent longitudinally running pin part connecting to the angled fixture end (10) secures from above the plate (1) in a notch (5) in the middle of the upper plate edge. The plate is thus secured against slipping downwards and simultaneous lateral displacement. The hook-shaped pins (6) are made of wire and the notches (5,4) in the upper and lower plate edge have a width which corresponds to the wire cross-section. The hook-shaped pins have a longitudinally running pin part (9) with a hook (8) bent to the side at one end and at the other end they have an angled fixture end (10) bent to the opposite side.
