1 Inch Self Tapping Screw can be drilled, tapped and fastened, all in one swift motion, saving the time and effort that you would have had to put in otherwise.
1 Self Drilling Screws Truss Head Phillips
Phillip modified truss head self drilling screws feature a drive and a self drilling point to pierce through 20 to 14 gauge metals.
The threads on these screws also cut their own threads into either wood, plastic or sheet metal. Modified truss head screws have a 100 degree undercut which creates a larger area beneath the screw's head for a larger bearing surface.
Truss head screws are generally weaker than any other type of screws, but they are preferred in applications requiring low clearance above the head. They can also be modified to reduce the clearance even further, while also increasing the surface of bearing.
