Description
Socket head screws (hexagon socket) to DIN 912, with socket head thread made of A2 stainless steel.
For fastening our module clamps or other components of the PV substructure in a slot nut. As a general rule: height of the module frame = height of the clamp. The appropriate screw length is usually determined by the module frame height + 5 mm.
Please refer to the following table for more details.
