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.
It can also be used for lighter applications like securing wood to metal. Since they are slotted, they can be removed using a screwdriver. Due to the excellent proportions with which these screws have been engineered, they often give an aesthetically pleasing look to the finished product or component.
