Round-Head Self-Tapping Screw with Press Washer

A self-tapping screw with a press washer is a fastener for working with timber structures.

It is a metal rod with threads and a special head. The head is wider than that of standard fasteners of this type and, once installed, covers a larger surface area, which improves the quality of the connection. The point comes in two types: a standard sharp point or a drill-type point. The recess in the head is most often designed for a cross-recess (Phillips) screwdriver.

Self-tapping screws are made of carbon steel and coated with a layer of zinc. The coating protects the fastener from corrosion, so the products can be used for both indoor and outdoor work.

How to use

For self-tapping screws with a sharp point, a pilot hole of a smaller diameter than the fastener must be drilled first. Without this, there is a high risk of damaging the material. Self-tapping screws with a drill-type point can be driven directly into the surface without a pilot hole.

These self-tapping screws can be purchased from FLOK.
