They hold together everything from the most delicate watch to the largest bridge. The world is literally kept from coming apart by screws and bolts, and yet we don’t often give a thought to these ...

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 ...

Measuring torque when installing threaded fasteners is the best indicator of future joint performance, right? Actually, bolt tension is a better performance indicator, but measuring torque is far ...

The GI-100DT uses a series of front and backlit cameras to calculate a part’s height, profile, and inner and outer diameters. Fasteners are critical components in engineered systems and structures, ...

Most engineers who deal with bolted joints are familiar with torque tables for SAE-grade bolts, but these are all too often used without regard for the yield strength of internal threads or the bolt’s ...

Threaded fasteners are galvanized in specialized galvanizing facilities that centrifuge the fasteners to remove excess zinc from the threads. Australian Standard AS1214 recommends the obligatory ...
