Nord-Lock Washers Iron, Sc Hardening Material NL3

Attaching the cover plate of the food processing machine is particularly attentive to contamination of the foreign people who is making the world aware of this recently. If we are even managing the torque on the near side of the machine, it is possible to prevent the bolt from coming off relatively, And it is difficult to prevent the bolt loosening of the part which is hard to see on the back side, so we are using pre-locked washer with pre-set torque to prevent loose dropout, after use, falling accident accident occurred We are not planning to use it next time machine overhaul of the next machine next time.

This product is wonderful. Even with hand tightening, there is a loosening prevention effect. Trying with a tool is necessary, if you try to demonstrate the original performance. Even with high vibration it is hard to loosen, as it does not compare with spring washer.

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.
