Products Description



1. Self-drilling screws, also called tek screws, do not require a hole to be drilled prior to use which cuts down on time needed to drill and fasten materials by combining them. These have the same heads as traditional bolts and screws, but the fastener is designed with a drill flute on the tip to drill/fasten at the same time. Useful for quick sheet metal fastening and other applications like metal to metal or wood to metal.
Self drilling screws have a drill bit point. Pan heads are slightly rounded with short vertical sides. Phillips drives are + shaped for a phillips screw driver.
