Nord-Lock Washers Iron, Sc Hardening Material NL3

I used it for maintenance of the astronomical telescope. It is the best to tighten properly when using a bearing. It can be tight enough without using a spanner. However, because I used it before using the bearing this time, I destroyed the worm gear of the drive section. The order of introduction was reversed (crying)

The principle of lock operation is simple and convincing. It is also appealing to be able to use it repeatedly. It is much more secure than Kikusa Washer or Spring Washer. However, the selection width of the size is small, in particular, it is unsuitable and careful to those with small screw diameter.

At the beginning of use, I was satisfied not to loose as expected. Although it seems that the loosening prevention effect is falling when used several times, as bolts and nuts are not loose and loose at present so far, they are generally satisfied.

Paris Dakar Machine Hino Ranger is also adopting parts, it will increase in weight, but reliability is high, I think that it can be lightweight if there is duralumin or titanium alloy made.

I used this product more than a spring washer because I thought that the anti-rotation effect was high. It seems that there is a proven record as patented products

Since you can lock the screw tightly, it is safe to loose parts. Since there is a thickness it is necessary to replace the screws short

It is locked securely and it does not become loose.

Both use and price are satisfied.

Because it was earlier and cheaper than buying at the dealer

There were places where the bolt loosened due to vibration, and there were places where the bolt was often dropped as well as loosening, but thanks to Kore, it will not be dropped afterwards. So we try to use this washer for other parts as well. But the disadvantage is high unit price.
