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

WHITEPAPER: BRIDGE DESIGN, CONSTRUCTION AND MAINTENANCE

In Europe, many bridges are part of an aging infrastructure built in the mid-20th century. As a result, existing bridges must be maintained, and new ones built to accommodate increasing traffic. Critical considerations influencing the choice of joining methods when building and maintaining bridges are history, regional preferences, and bridge type.

Why Nord-Lock washers

10 reasons that speak for Nord-Lock

Dynamische Beanspruchungen: Wechselnd, Stroßbelastung, Vibrationen, Temperatur Dynamic loads: Alternating or shock loads, vibration, temperature
Normen empfehlen oder schreiben Sicherungsmaßnahmen vor Standards recommend or prescribe locking elements
Vorspannung allein ist kein Garant für ausreichende Sicherung Preload alone is no guarantee of adequate locking function
Andere Sicherungsmethoden sind wirkungslos (z.B. Kontern, Körnen, Palmutter, etc.) Other securing methods are ineffective (e.g. double nut, thread punching, pal nut, etc.)
Erhält die Vorspannung (Konstruktionsprinzip einer Schraube) Maintains the preload (design principle of a bolt)
Verhindert das Auseinanderfallen der Komponenten Prevents the bolting components from falling apart
Konformes Sicherungselement (ETA, abZ, EBA) Conform securing element (ETA, abZ, EBA)
Reduktion von Instandhaltungsmaßnahmen /-kosten Reduction of maintenance activities and costs
Unkompliziert (flache Scheibe durch Nord-Lock austauschen) Easy to use (replace flat washer with Nord-Lock)
Lebenslange Garantie auf die Sicherungsfunktion Lifetime warranty on the securing function
Tested and certified

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."
