The DIN 7971 screw is a semi-circular head screw with a straight slot that is used for fastening parts to soft materials such as wood, plastic or soft metals. The semi-circular shape of the head allows the screw to sink into the material without damaging its surface, which is important when it is important to preserve the appearance of the part.
