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 ...

A technique to manage an unusual presentation of an implant abutment screw fracture is presented. Causes of abutment screw loosening and fracture are reviewed. Design features that improve the ...

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 ...

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 ...

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 ...
