EXPERT INSIGHTS
DURABLE BOLTED JOINTS IN STEEL CONSTRUCTION
There's plenty that goes into finding the best solutions for and securing critical bolted connections, not least in steel construction.


UNMATCHED PERFORMANCE IN THE JUNKER TEST
The most severe vibration test for bolted joints, The Junker test*, compares different securing methods under transverse displacements while continuously measuring the clamping force between the structural parts. The preload is crucial to hold the parts together and prevent loosening - otherwise, the bolted joint would fail.
* According to DIN 65 151

Ensuring industrial lifelines
"With preloaded bolts, we need to ensure that they don’t lose the preload. A perfect way to do this is to use Nord-Lock wedge-locking washers. But regrettably, I receive almost daily proposed solutions with lock nuts or pall nuts, which are entirely unsuitable. This is because many construction engineers are not familiar with dynamic load."
