Hammer fixings feature a long plug made of polyamide 6.6 with 6 wings and a hex-head countersunk screw. Thanks to the countersunk neck of the plug, the anchors will be flush with the fixing material. It furthermore prevents the plug from being pushed completely into the hole during installation. These fixings are very easy to insert and remove thanks to their thread and point, as a hammer blow is only necessary for its installation. They can also be screwed as a standard screw. The hammer fixings are flexible during assembly, being also available in a wide range of diameters and lengths: Ø10mm in diameter and lengths of 120mm, 140mm and 160mm.
