and n is the number of inclined screws in a row. If crossed pairs of screws are used in timber-to-timber connections, n is the number of crossed pairs of screws in a row.Outer diameter of washers dh > 35 mm shall not be considered.Note: For inclined screws as fasteners in mechanically jointed beams or columns or for the fixing of thermal insulation material, nef = n.The minimum thickness of wood-based panels according to the clause 3.9 must be observed.In steel-to-timber connections the head pull-through capacity is not decisive.Page 9 of 37 of European Technical Assessment no.
