Pozi Flange Head Self Tapping Screws BZP Packs of 100

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.
