Proven in Junker Vibration Test
The Junker test, according to DIN 65151, is considered the most severe vibration test for bolted connections. During the test, the joint is exposed to transverse movements underneath the bolt head / nut, while the clamping force is continuously measured. Nord-Lock washers are proven as a safe bolt securing system according to DIN 65151 tests performed by the independent research organizations IMA and CETIM. In addition, Nord-Lock personnel perform over 10,000 live Junker vibration tests around the globe every year.
Nord-Lock Washers provide more than just a safe locking function, using Nord-Lock products also improves the general performance of a bolted joint.
