Applications

Self-drilling screws, often called self-tapping screws, have advantages over conventional screws in that they eliminate the need to drill a pilot hole before insertion. This can save both time and effort in many fastening applications, while delivering the same security and versatility of a conventional screw. Self-drilling screws should always be installed using a power-driver and are therefore particularly suited to fast production environments.They can be used in light and heavy gauge sheet metals, soft plastics etc, and are ideal for applications in heating and air conditioning, metal and fiberglass fabrication industries.

What are the advantages of hexagonal head screws?

Hexagonal heads typically have a larger head than conventional screws, which results in higher clamping pressure, which may be a concern when you need confidence in fixing surfaces together. They typically require a socket or spanner to tighten and loosen, which is often a less strenuous way to apply maximum torque than other drivers.
