M10 double-threaded screw

Assembled double-threaded screw M10x200 made of stainless steel A2 1.4301 used for mounting photovoltaic systems.

The complete set includes: a double-threaded screw, 3 flange nuts, and an EPDM washer.

The threaded end is screwed directly into the wooden roof structure. The other end is used for attaching adapters with flange nuts.

Double-threaded screws are also used for mounting triangles on flat roofs.

The screw with a double thread comes as a set with flange nuts and an EPDM washer.

The integrated flange nut and EPDM washer serve to seal the contact surface.

Stainless steel A2 - is a high-alloy material with an increased chromium content, resulting in greater resistance to oxidation (corrosion). With a low carbon content, the material is more susceptible to hardening, providing greater durability and strength.
