Washers from carbon steel should be used with screws from carbon steel and screws from stainless steel with washers from stainless steel. Washers should have a full bearing area.Unless specified otherwise in the technical specification (ETA or hEN) of cross laminated timber, minimum distances and spacing for screws in the wide face of cross laminated timber members with a minimum thickness t = 10∙d may be taken as (see Annex C):a1 = 4 ∙ d a2 = 2,5 ∙ dSpacing a1 parallel to the grain Spacing a2 perpendicular to the grain Distance a3,c from centre of the screw-part in timber to the unloaded end grain Distance a3,t from centre of the screw-part in timber to the loaded end grain Distance a4,c from centre of the screw-part in timber to the unloaded edge Distance a4,t from centre of the screw-part in timber to the loaded edgea3,c = 6 ∙ da3,t = 6 ∙ da4,c = 2,5 ∙ da4,t = 6 ∙ d
