The M2.5X16/D912-A4 part of Kraftberg is a high strength self-tapping screw. It is suitable for heavy duty applications, primarily in wood and soft metals. The screw features an ultra-sharp Type A point, which helps reduce the amount of force needed to drive the screw into wood, and ensures an excellent hold. The head of the screw is round with 8 protrusions, which allows it to be used in most standard drill sizes. The edges of the head also include lubricity bands to make driving easier. The zinc plating of the screw helps protect the material from corrosion, making it ideal for outdoor use.
