Fasto Galvanized Hex Head Self Drilling Screws for Metal Roofing with EPDM Washer

A self-drilling screw is a type of screw that has similar design features with a drill bit with a tip that enables it to drill its own hole. As the name implies, self-drilling screws do not require a pilot hole in order to perform as a fastener. They are designed to work on soft steel, wood, and metals.

The selection of self-drilling screws requires the examination of certain parameters in relation to their use. The initial and practical aspect is the thickness and type of material to be joined since certain self-drilling screws are designed for specific materials. Another important aspect of self-drilling screws is their drill load or the amount of force placed on a drill during install.

When making the decision to use a self-drilling screw, it is important to first consider the type of materials to be connected. The key factors for an efficient, operating self-drilling screw are the types of points, which include the flute, length, and wings.
