A coarse thread self drilling button head designed for a range of applications such as fixing light sheeting and cladding that require a flat head underside to allow for greater bearing on the surface material. The coarse thread allows for a slightly faster install, whilst the self drilling point (aka tek point) eliminates the need for pre-drilling (please see screw self drilling capacities). The No. 2 Square drive (positive non-wobble install) accompanied by the button head provides a capable screw with an aesthetic finish. Available in zinc clear finish making this screw suitable to low corrosive dry environments.
