Csk Head Phillips Self Drilling Screws

Csk head self-drilling screws from CBH Fasteners are highly durable and corrosion resistant, which allows it to be used in extreme temperatures and undersea applications as well. Since these screws are self-drilling, they can be used without drilling the pilot hole. Contrary to conventional methods of manufacturing, these screws are particularly made with two materials, one for the head and shaft, and another for the drilling tip. The tip is made of a harder material to allow precision fastening of metals. The addition of carbon drastically increases the strength of the material while making it extra strong.
