3.5mm x 25mm Pozi Flange AB Self Tapping Screw BS 4174 | Black Zinc Steel

This 3.5mm x 25mm Pozi flange fixing is useful for assembly points where the screw must start cleanly and sit securely against the workpiece. The PZ2 drive is useful where repeat driver engagement is part of the fitting process.

The head form is useful for spreading load over slotted holes, plastic components and light sheet sections where a small bearing area may mark the surface. The BS 4174 reference also helps buyers keep specification records consistent across maintenance orders.

Choose the thread size and length to suit the pilot hole, material thickness and clamping depth. The flange head can spread load across the fixing point without a separate washer in many assemblies.
