A connection arrangement for boards, panels or slats ( 1 ) made from wood pr of wood materials to a metallic substructure ( 2 ) is provided. The screws ( 3 ) that are used include a screw head ( 4 ) and a shank ( 6 ) provided, at least over a portion of its length, with a thread ( 5 ). The screw ( 3 ) is screwed in from the side of the metallic substructure ( 2 ) and engages, via the shank ( 6 ) provided with the thread ( 5 ), inside the boards, panels or slats ( 1 ) made of wood or of wood materials. An essentially non-threaded shank section ( 7 ) is provided between the screw head ( 4 ) and a beginning of the thread ( 5 ) on the shank ( 6 ). The length of this non-threaded section corresponds, at least approximately, to a thickness (D) of the metallic substructure ( 2 ) through which the screw ( 3 ) is to pass. The outside diameter (A) of the thread ( 5 ) is made larger than the diameter (U) of a bore ( 8 ) made in the metallic substructure ( 2 ).
