Junker Test
During the Junker Vibration Test (DIN65151), clamping force in other solutions decreases sharply after just a few seconds. This is because other anti-loosening measures for bolt connections are based on friction. Yougu wedge locking washers, on the other hand, use geometric principles to achieve wedge self-locking technology, effectively addressing bolt loosening issues. This prevents downtime for maintenance and potential safety hazards, significantly reducing production costs for enterprises.

In our production tests, we strictly adhere to the Junker Vibration Test (DIN65151), which is the most stringent vibration test for bolt connections. This test evaluates the loss of preload and bolt connection failure caused by vibration or load conditions through lateral shear at a fixed frequency on grade 8.8 bolts.
