VIBRALOCK® is a patented new mechanical lock nut system that will make annual inspection and re-torque checks of your standard HV bolting connections redundant.
The VIBRALOCK® technology is based on the use of two nuts working on different thread diameters and pitches. No loosening can occur due to the friction forces between the two nuts combined with the difference in pitch. Installation time for the VIBRALOCK® bolts is the same as standard HV bolts and both installation and retrieval require no proprietary tooling.
In 2021, a laboratory test acc. to ISO 16130:2015 (Junker vibration test) to prove the VIBRALOCK® technology was performed at the University of Stavanger with EXCELLENT results. See detailed results incl. graph in the link below.
