Swiss "invisMX" Magnetic Invisible Screws
Screws are a common component. Fastening screws onto an object will inevitably leave the screw head on the connecting part of the surfaces and undermine visual appearance. In light of this, a Swiss company invented an invisible magnetic screw which leaves no screw marks when used to fasten object. This screw is named invisMX magnetic invisible screw, and it has a strong bearing capability at a maximum of 400 kilograms.
The screw was invented by Lamello AG Joining Technology from Switzerland. It can stay hidden and fasten the internal part of objects. It is somewhat similar to the mortise and tenon in Chinese building structures but simpler and more convenient. All that is needed is to punch a small hole on the wood, install the screw into the hole on one end of the wood, and drive in the nut on the other end, utilizing connection of two pieces of wood and a magnetic tool to fasten the screw and nut. This is all done by utilizing unique magnetic attraction repulsion. The removal of the screw is very convenient, and all that takes is to use related magnetic tools which will remove the screw within seconds. The screw can make wood connection very firm and has a strong grip with the torsion force reaching 160 kilograms. It is currently applied to the process of furniture production.
