For inclined screws in timber-to-timber or steel-to-timber shear connections, where the screws are arranged under an angle 30° ≤ ≤ 60° between the shear plane and the screw axis, the effective number of screws nef should be determined as follows:For one row of n screws parallel to the load, the load- carrying capacity should be calculated using the effective number of fasteners nef, whereCharacteristic head pull-through parameter for screws in connections with wood-based panels with thicknesses between 12 mm and 20 mm: fhead,k = 8 N/mm²Screws in connections with wood-based panels with a thickness below 12 mm (minimum thickness of the wood based panels of 1,2∙d with d as outer thread diameter): fhead,k = 8 N/mm² limited to Fax,Rk = 400 Nefn max n0,9 ; 0,9 nThe head diameter dh shall be greater than 1,8∙ds, where ds is the smooth shank or the wire diameter. Otherwise the characteristic head pull-through capacity Fax,,Rk = 0.
