Features & Applications
BZP Pozi Roundhead Twin ThreadTwin thread woodscrews consist of two threads, one inside the other. This means the screw pitch is much greater than with a single thread so that the screw drives in considerably quicker but with high retaining power. These screws are ideal for all softwoods. The core diameter is greater than for a chipboard screw, making them the preferred choice for use in expansion plugs.
