Wooden screws


We as a developer of carbon steel wood screws have a lot of knowledge about the use and design of the wood screw. Carbon steel is a very nice material to make a strong screw but steel is a mineral and scarce raw material so my idea is to develop a wooden alternative for the steel wood screw, made from wood. I believe that it's possible to make a screw from wood, not the same design of course as the steel version... I only have the idea so far and I'm looking for specialists in CNC woodworking to do some experiments and testing of this idea.

  • The idea has some potential. I have seen wood dowels, where the dowel is dried to an extremely low moisture content and the surrounding material is not. The hole for the dowel is slightly undersized and the dowel is driven into the wood. The equalizing of the moisture content in the wooden dowel then makes it swell which locks the wood panels together. There could be some real scope to develop new techniques with "wooden screws" in a similar way.
  • That's great idea! I'd assume less resistant as classic steel-based screws, but I could see an application in traditional carpentry, to lock and secure traditional assemblies, in a classic and full-wood style. Hope you'll find some CNC partner, and perhaps a wood specialist to chose the right wood species.
