There is a setting of panels with moulding elements- screws, nuts, pins, studs and pillars (stainless and aluminum) in a version for different screws' heads - recessed, hidden, in order to facilitate the assembly and completion.
These elements can be fitted so that no visual disturbance of the panel can be seen from the front side of the panel.
The advantages are exceptional durability, high precision and usability, even for panels with surface treatment.
