The ratio of inner thread diameter to outer thread diameter di/d ranges from 0,59 to 0,69.The screws are threaded over a minimum length g of 4,0∙d (i.e. g > 4,0∙d).The lead p (distance between two adjacent thread flanks) ranges from 0,50∙d to 0,67∙d.No breaking of screws shall be observed at a bend angle, , of less than (45/d0,7 + 20) degrees.The material specification of the of the stainless steel screws is deposited with ETA-Danmark.Specification of the intended use in accordance with the applicable EAD The screws are used for connections in load bearing timber structures between members of solid timber (softwood and hardwood). Furthermore, all kinds of processed timber products (all softwood and hardwood as well), such as glued laminated timber, cross-laminated timber, laminated veneer lumber, similar glued members, wood-based panels or steel.
