What are self drilling screws used for?

Self drilling screws have a point that acts as a drill bit and sharp cutting threads that tap the hole during installation. Self drilling screws are a commonly used variety of screws for quick drilling into both metal and wood. A self drilling screw can typically be identified by its point and flute (notch) tip.

Perguntas mais frequentes

They are measured from the top of the head to the tip. Hex and hex washer head screws and bolts, although flat on the top and the bottom, are measured from the bottom of the head. From that point to the tip is the length of the screw. Self drilling screws are measured all the way to the end of the drill point tip.

 While self-tapping screws will tap a hole into a soft material, self-drilling screws are capable of drilling a hole into anything from metal to wood. This key difference is self-drilling screws have a tip like a drill bit, so they do not need a pilot hole.

Self-drilling screws eliminate the need for a pilot hole but can tap as well. Self-tapping screws tap their own threads, but cannot drill through metal and require a pilot hole. These screws are not interchangeable, and mixing up the two can cause many headaches or possible failures in the field.

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 oversized 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.

Do you need a drill for self-tapping screws? No, self-tapping screws can simply be inserted with either a screwdriver. However, it’s better to drill a small pilot hole before the you drill the screw

To summarise: Self-Tapping – a screw for securing thinner sheet metals and other substrates that cuts its own thread, but usually requires a predrilled or pre-punched hole. Self-Drilling – a screw that can, well, self-drill through various gauges of metal materials without predrilling.
