Abstract: The invention relates to an assembly aid for positioning a hinge (1) on a door arrangement part (12) in a reproducible manner, said assembly aid comprising a clamping screw (22) having a screw shank (23) and a screw head (21), and an adjusting element (20) which is applied to a part (17) of the hinge (1) in a positively locking manner. The adjusting element (20) radially engages with said screw shank (23) and can be axially fixed to the door arrangement part (12) by means of the clamping screw (22). The invention also relates to a method for the reproducible positioning of a hinge (1) on a door arrangement part (12) whereon a positioning axis (30) is provided. The aim of the invention is to provide an assembly aid and a method that enable a hinge to be precisely positioned in a simple and reproducible manner.
