The average thickness of the zinc deposit is about 60 to 70 microns, it is necessary to use oversized nuts. (Nuts and washers on request). To facilitate the mounting of the nut, the threaded rods of a length inferior to 550 mm undergo a spin-drying operation. The rods of a superior length are brushed hot to remove zinc overload ends. Brushing is about 600 mm, all the rods measuring more than 1200 mm have a central part which is not brushed.
