The double articulated bolt allows for variable angle edge joints in wooden boards, with a discreet, but stable and secure finish. It is part of the 10 mm diameter System hooking system, so it must be used in conjunction with the plungers and screws for hooking the same line. The piece is made of turned steel and has a zinc-plated finish that guarantees durability. The bolt body has a diameter of 7mm and its overall length is 89mm, with the hinge joint right in the middle and the hooking points at the ends. The packaging contains 500 units.
