Question 1

1. What is a self-drilling screw?

Accepted Answer

A self-drilling screw has a tip shaped like a drill bit, allowing it to cut into materials without the need for a separate pilot hole.

Question 2

2. What’s the difference between a self-drilling screw and a self-tapping screw?

Accepted Answer

Tek screws, or self-drilling screws, have a drill-shaped tip that creates a hole and taps threads in one step. They’re ideal for metal-to-metal or timber-to-steel fixings. Self-tapping screws need a pre-drilled hole and only cut threads as they’re driven in. In short: Tek screws drill and tap, self-tappers just tap.

Question 3

3. Can you use Tek screws on timber?

Accepted Answer

Yes, self-drilling wood screws are designed for timber applications, especially when fixing timber to light steel sections.
