10-16 x 16mm Self Drilling Steel Tek Screws

10-16 x 16mm Self Drilling Steel Tek Screws.

Available in various colours.

Product Overview
Our Tek Screws are designed with a hardened self-drilling point, making it easy to cut through mild steel and aluminium, without the need for pre-drilling. The hex head allows for a quick and secure installation, while the coarse thread ensures a strong hold in sheet metal and other thin steel materials. With a galvanised coating, these screws are perfect for most outdoor applications.

Ideal for usage on our Colorbond fencing range, pool fencing, or Acacia and Banksia panels.

Features and Benefits:

• Self-tapping for easy installation
• Available in Galv or 25 Colorbond Fencing colours
• Hex head drive for fast, secure fastening
• Available quantities: Each, Bag of 50, Bag of 100.

Handy Information for Self-Tapping and Self-Drilling Screws

Choosing the right screw for the job is essential. Here’s some helpful information about Self-Drilling and Self-Tapping Screws to make sure you’re using the correct one.

Self-drilling screws, also known as TEK screws, are a type of self-tapping screw that comes with a drill point. The drill point is designed to create a pilot hole as it fastens into the material. Right behind the drill point are self-tapping threads that cut into the material, securing the screw in place.

On the other hand, self-tapping screws don’t have a drilling point. They’re best suited for securing thinner sheet metals and other substrates. When working with thicker materials, a separate pilot hole will need to be drilled beforehand.

Understanding the Drilling Capacity of Self-Drilling Screws

When determining the drilling capacity of self-drilling screws, it’s important to take into account the drill flute, the point length, and whether you're fastening thicker materials to metal. These factors will influence how well the screw performs.

• Drill Flute: The flute’s height dictates the thickness the screw can penetrate. If the flute becomes fully embedded, debris can get trapped, causing heat buildup and potentially breaking the screw.
• Point Length: The unthreaded section, called the pilot, needs to be long enough to fully penetrate the material before the threads engage. If the threads catch too early, the screw might bind and break since the threads move faster than the drill.

Incorrect usage of self-drilling screws can lead to a few issues. Below is a troubleshooting guide that offers solutions for some common problems that can arise. Fort more info, you can also visit "Self-Drilling Versus Self-Tapping Screws: A 3D Finite Element Analysis"
