Secure sheet metal, plastics, and components with absolute confidence using our Pozi Flange Head Self Tapping Screws. Supplied in trade-friendly packs of 100, these fasteners are the perfect solution for blind assemblies where only one side of the material is accessible. Featuring a built-in flange to distribute the clamping load and a sharp AB point for precision thread cutting, they provide a fast, reliable grip without the need for a separate nut or washer.

Built-in Flange: Spreads the clamping load over a greater area, protecting delicate materials and eliminating the need for a separate washer.

Sharp AB Point: Specifically designed to easily start and cut its own precise thread into pre-drilled sheet metal and plastics.

Corrosion Resistance: Finished in a Bright Zinc Plating (BZP) for reliable protection against rust in dry and indoor environments.

The Flange Head Advantage

When fastening thin sheet metal or brittle plastics, using a standard pan or countersunk head can concentrate too much pressure in a small area, pulling the screw through the material or causing it to crack. The flange head design solves this problem elegantly. It features an integrated washer-like collar at the base of the head, which greatly increases the bearing surface. This spreads the clamping load over a much wider area, providing a secure, flush hold without warping your sheet metal or crushing plastic components.

Efficient Single-Sided Assembly

One of the biggest challenges in fabrication and automotive repair is blind fastening—needing to attach a component to a surface when you can't reach behind it. These self-tapping screws are engineered exactly for this scenario. Equipped with a sharp AB point, they catch the edge of your pre-drilled pilot hole instantly. As you drive the screw in, the hardened threads act like a cutting tool, carving their own perfectly matched mating thread into the material. This provides exceptional pull-out resistance and grip, entirely removing the need for a matching nut on the other side.

Reliable BZP Protection

Consistency and durability are key when buying fasteners in bulk. Every screw in this 100-pack conforms to the rigorous BS4174 standard, meaning you won't encounter malformed threads or easily stripped heads. To protect the high-strength steel core, they are finished with Bright Zinc Plating (BZP). This clear zinc coating not only looks clean and highly professional but acts as a sacrificial barrier against oxidation, keeping your interior assemblies rust-free and structurally sound.

Frequently Asked Questions

Do I need to use a washer with these screws?

No, that is the primary benefit of the flange head. The built-in flange acts as an integrated washer to spread the load, saving you the time and cost of fiddling with separate flat washers.

What does "AB Point" mean?

An AB point denotes a screw with a sharp, gimlet point and fine threads. It is the most common and effective point type for self-tapping into thin sheet metal and plastics.

Do I need to drill a pilot hole first?

Yes. Unlike "self-drilling" screws (which have a drill-bit tip), standard "self-tapping" screws require a pre-drilled pilot hole. The screw then taps (cuts) its own thread into the sides of that hole.
