Head Self Tapping Screw

What is Modify Truss Head Self Drilling Screw?
Phillips modified truss head self drilling screws feature a phillips drive and a self drilling (TEK) 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. Phillips modified truss head screws feature an over-sized domed head with a flange, similar to an integral washer. Modified truss head screws have a 100 degree undercut which creates a larger area beneath the screw's head for a larger bearing surface.
