Mounting cowl of race bike
From Japan
On 2015-11-20 18:55:33
Since the race bike runs at high rotation all the time, the screw loosens due to vibration and falls off often. I use it to prevent it. It is hard to loosen and it's quite nice.

There is no looseness due to vibration, and work can be done safely. Initial expenses will cost more than normal double nuts, but I think that it is cheap in the long run.

According to the singing phrase, the loosening prevention effect is very high, and the effect is sustained, it is a convincing commodity. Moreover, since it is possible to loosen it easily when loosening it, it is used very conveniently.

Strong vibration location of agricultural tractor
From Japan

The standard is U-nut M20P1.5, but since it is a place where it vibrates very strongly, just in case, I fixed it and installed it. I got absolute relief with this.
