Introduce

Pan Head Self Drilling Screw 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 screw for quick drilling into both metal and wood. A self drilling screw can typically be identified by its point and flute (notch) tip.

Pan head screws take their name from the appearance of their head, which looks similar to an upside-down frying pan.

Advantage.

• Self drilling screw is a type of self-tapping screw that also features a drill point. The sharp drill point will both drill a hole and form the mating threads in a single operation.
• 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.

The difference between self-tapping screws and self-drilling screws

• The most important difference between self-tapping and self-drilling screws is that self-tapping screws cannot go through metal without a pilot hole, which must be pre-drilled or pre-punched.
• Unlike self-tapping screws, self-drilling screws need no pilot hole to cut and fasten; they can drill, tap, and fasten in one go, which saves you the extra step of drilling, then fastening.
• Etween these two, however, self-drilling screws offer two distinct advantages: time and costs saved at assembly time, and reduced error in installation, which often happens if one pre-drills holes in the wrong size.
