Dacromet range of Welfast Self Drilling Screws provide a pollution-free ceramic coating solution. The coating offers corrosion protection due to hot-dip galvanizing without discolouring the base/wood. These Screws with proper dacromet coating typically withstand a 1000-hour salt-spray test, greatly minimizing the risk of hydrogen embrittlement thus eliminating the need of baking parts after the finish is applied.
