ABSTRACT:
An expansion dowel has an axially extending sleeve-like expansion member with a first portion arranged to be inserted into a bore hole and a second portion arranged to extend axially from the bore hole. A stop member is securable on the second portion for holding a panel or similar part between the stop member and the rear or outer end of the expansion member in spaced relation to the support structure in which the bore hole is formed. The stop member includes a locking member axially displaceable on and securable to the second portion and a supporting member adjustably threadedly engaged with said locking member and positioned between the locking member and the rear end of the expansion member. With the locking member fixed on the second portion, the supporting member can be adjusted for holding the panel or similar part between it and a support surface on the rear end of the expansion member.
