Ps. Only use stainless steel cables. This is 7x7 strict, which means that the clamping is optimal.
A 4 mm steel cable can be inserted on one side of the terminal. The fine screw thread creates a high tensile force here. After inserting the cable, it can be clamped by tightening the clamp, no special tools are required. This can be done with a spanner 13. On the other side a stainless steel bolt M8 can be screwed in, but you can also screw in a yoke here. Everything can be combined with it as long as the wire is M8.
