Until now, the STEMFIE construction set only had shoulder screws as a threaded fastener, meaning each screw had to have the correct length when fitting parts together.
Today a new type of fastener is ready for download: the fully threaded screw with a rounded head. You can now use the entire length of this fastener to connect two or more parts.
Use this link to download the screws ranging from 0.25 to 10.0 STEMFIE block units.
This toy is unsuitable for children under three years due to choking hazards!
