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.

These Flat Head screws have a point “like a drill bit”, these screws create their own hole, and their own 
thread in one action.
This is probably where the confusion with self-tappers comes in – both kinds of screws are technically 
self-tapping as far as the function of their threads are concerned, but the massive difference is in the
 function of their points.
