It’s easy to cut bolts and small machine screws to length. On the other hand, there isn’t any job so small or simple that it can’t be done wrong, and this is a classic example. Get it right, and you ...

Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism ...

Threaded inserts are great for melting into FDM prints with a soldering iron. The process isn’t so simple for resin prints, since they don’t generally soften with heat. Off course, you can also print ...

Attaching metal pieces to one another with a screw is relatively straightforward. But using threaded fasteners on plastics, which are lightweight, low-density materials compared to metals, can be ...

Self-tapping screws are also one of the most important tools at home as well as in metalwork. These distinctive ...

Ball screws and roller screws are widely used for high-force linear motion and are replacing fluid power devices. In general, these screw mechanisms generate linear motion by rotating either the screw ...
