Advantages of hexagon screws
Unlike screws with a slot or Phillips head, external hexagon screws can also be used when the screw head is no longer accessible from above. In addition, hexagon screws are suitable when there is a lack of space due to their relatively low head height. High tightening torques allow high-strength connections.

Design and standardization
Hexagon screws are currently subject to the current ISO standard. Compared to the expired DIN standard, the width across the head has been reduced (in order to save material during production). Nevertheless, hexagon screws are still produced according to DIN 931 (partial thread) or DIN 933 (full thread) with metric thread. The variant with a wood thread is DIN 571. However, these are increasingly being replaced by special wood construction screws with alternative head and drive shapes.

Materials for hexagon screws
Hexagon screws for outdoor use should be made of at least A2 stainless steel. If there is permanent contact with water or temporary contact with salt water or acids, A4 stainless steel should be used. For applications in steel construction or mechanical engineering, high-strength screws with strengths of 8.8, 10.9 or 12.9 are available. These are available either bare or surface-treated (e.g. galvanized or hot-dip galvanized).
