A self-drilling screw is a type of screw designed with a drill point tip that can drill its own pilot hole, tap threads, and fasten materials together in a single operation, eliminating the need for pre-drilling.
Self-tapping screws tap their own threads but require a pre-drilled pilot hole. Self-drilling screws, on the other hand, feature a built-in drill point tip that drills the hole and taps the threads at the same time.
Modified truss head self-drilling screws feature an oversized head with a low-profile dome. They are ideal for securing thin metal sheets, wire mesh, or metal lath to steel or wood framing where a low-profile head is required.
Yes. Depending on the size of the drill point (often classified from #1 to #5), self-drilling screws can penetrate various thicknesses of metal plates. Make sure to choose the correct point size matching your material thickness.
We offer both standard Phillips drive and Square drive configurations. Square drive options are highly recommended for applications requiring higher torque transfer and reduced driver slippage.
