KonstruX ST, countersunk head stainless steel A4

KonstruX ST A4 maximise a joint’s load-bearing capacity with a high thread-extraction resistance in both components. If partially threaded screws are used, the joint’s load-bearing capacity is limited by the considerably lower head-pull-through resistance in the attached part.
