These zinc plated self-drilling screws offer all the advantages associated with standard self-tapping screws but are capable of drilling their own pilot holes into sheet metal up to 5mm in thickness. As it has a flange head, it doesn’t require a washer to distribute the pressure of the nut.
This hexagonal self-tapping screw features a wide thread and robust hardened steel drill point.
Hexagonal heads typically have a larger head than conventional screws, which results in higher clamping pressure, which may be a concern when you need confidence in fixing surfaces together. They typically require a socket or spanner to tighten and loosen, which is often a less strenuous way to apply maximum torque than other drivers.
