Food processing machine cover plate mounting
From Japan
On 2018-04-07 21:31:17
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.

Installation of mechanical parts with vibration such as high heat
From Japan
On 2017-12-19 21:28:44
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.

Maintenance of the astronomical telescope
From Japan
On 2017-04-28 23:53:31
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)

Personal hobby work such as assembly of chassis parts of a vehicle
From Japan
On 2016-10-14 18:34:55
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.

Used as a substitute for spring washer when fixing self-propelled grass cutter blade
From Japan

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.

Loosen bike locking prevention
From Japan

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.

Prevent loosening of bolt joint
From Japan
On 2015-11-14 17:01:32
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

Engine parts looseness prevention
From Japan

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
