A special thread form keeps bolts and nuts tight under vibration by attacking the problem from a different angle. Two conventional methods for securing threaded fasteners against preload loss include ...

Simplifies tool selection. One thread mill can machine all materials up to 58 Rc. This guarantees a safe, highly controllable process, in which a simple modification to the CNC program corrects for ...

The strength of some internal threads is more sensitive to tap diameter than previously thought. • Cold-formed threads are no stronger than cut threads when holes are correctly sized. • Cut threads ...

Thanks to advances in materials and electronics, we are starting to see how our clothing might one day do more than keep us warm or protect us from the elements. Scientists at Chalmers University of ...
