Unlike machine screws, which require a pre threaded hole to be used, our range of self tapping screws can tap their own holes into the surface. Our range of self tapping screws also includes self drilling screws which have a drill like flute on top enabling one step installation. Available from 2 mm to 150 mm in height, and accordingly from 2 mm to 16 mm in thickness, our wide range of self tapping screws provide long lasting fastening solutions. By making holes for themselves, these screws save precious time and effort by combining the process of drilling, tapping and installing.
