Galvanized steel. Contracting bottom thread. Gapless mounting. For all Queenply thicknesses.
These partially threaded screws with a contracting underhead thread can be used wherever you need a quick and gap-free tightening of wood-wood connections. Due to the underhead thread with low thread pitch and enlarged outer diameter located below the screw head and thanks to the cupped milling elements in the tip, the gap-free connection of second lightweight panels works. And thanks to the partial thread starting immediately after the shank, tightening is possible. In the process, the thread is positioned completely in the lower second component. And it holds really strong.
These screws are suitable for all our Queenply thicknesses and finishes. We have them in a length of 30 mm and with a diameter of 3.5 mm here in our store.
You can find more technical information under “Technical Details”.

Before you start further processing and finishing work on our lightweight panels, please make sure that you have adequate protective measures in place, such as wearing safety goggles and, if necessary, a face mask. For drilling or sawing work, it is advisable to additionally wear hearing protection.
Especially with our coated panel materials, the ambient temperature is important during processing. Therefore, make sure that the room temperature is comfortable when you start.
