Nut with Bonded Washer

[Features]
· Because the BD washer and the hex nut are set using a unique assembly technology, the rubber will catch on the opposing bolt when tightened to obtain excellent sealing effects.
· High anti-loosening effect due to the damping property of the rubber, and the rubber contacting to the tightening object results in sound absorption effect and insulation effect, and it does not scratch the bearing surface.
