Self-Tapping Screws

About Self-Tapping Screws

Self-tapping screws are commonly used for stitching metal to metal where a strong, reliable fixing is required without the need for tapping threads. They’re widely used across construction, fabrication, electrical installation and general maintenance work.

All self-tapping screws in this category are designed for use with a pre-drilled pilot hole, allowing the screw to form its own thread cleanly in metal. This gives greater control during installation and helps reduce stress on both the screw and the material being fixed.

Self-Tapping Screws for Metal Fixing

Self-tapping screws for metal are ideal for fixing sheet steel, brackets, box section and light steel components. Once the pilot hole is drilled, the screw cuts a precise internal thread, creating a secure hold suitable for everyday trade use.

These fixings are commonly used in applications such as:

• Sheet metal fabrication
• Electrical containment and trunking
• HVAC and ducting
• Brackets, plates and metal framing
• General repair and maintenance work

Using a pilot hole improves accuracy and helps reduce the risk of snapping, particularly when working with harder materials.

Head Types Available

This category includes several head styles to suit different fixing requirements:

• Countersunk self-tapping screws - sit flush with the metal surface and are ideal where a neat finish is required or where panels need to sit flat.
• Pan head self-tapping screws - provide a larger bearing surface for improved clamping strength, making them suitable where holding power is the priority.
• Flange head self-tapping screws - feature an integrated washer that helps spread load and reduce pull-through on thinner metal.
• Self-tapping screw trays - mixed selections of popular head types and sizes, ideal for vans, workshops and maintenance teams.

Each option is designed to give consistent results depending on finish, load and application.
