Stairs are more than a mere connection between two points – they play a key role in the overall appearance of the interior design concept. And they need to be functional with a high load-bearing capacity over a long period of time, too. Wooden stairs are therefore usually made using native hardwoods such as oak or beech. Together with the right surface coating, their hardness ensures that the steps do not wear out even after a long time. Of course, this is only possible in combination with fasteners designed for hard woods.
What do I need to know?
When walking on, high dynamic loads are exerted on stairs, which screw connections must absorb. Otherwise, the stairs might start to "creak" when the treads and risers rub against each other. Suitable screws should therefore also be capable of preventing such minimal movements. And keep the entire construction looking good – at least in the case of visible screw connections in interior projects.
