Nord-LockWedge Locking Washers - Steel (Delta Protekt) Washer with Zinc Flake Coating, Vibration Resistant Safety Washers for 3/8 Inch Bolts - 20 Pairs

Picked up a set of these to install on the axle shafts of my 2019 Pacifica and they work like a charm.For some reason the Pacifica doesn't have any sort of "locking" mechanism for their axle nuts, not even any sort of knurling on the face of the nut. You torque it down to the recommended foot-pounds and a a week later it has loosened itself. Some have tried going with a higher than recommended torque value and they still loosen up. This is happening to a surprising number of people based on what I've read in a Pacifica forum.Some bright sole in that forum came across these and gave them a try. Worked like a charm them. Other have tried them and had the same success. I figured what do I have to lose, so I bought a set myself, installed them, and torqued the nuts to the recommended value. I am very happy to say that I have checked the axle nuts 3 times over the last few weeks, and they are no longer backing off and loosening up. These lock washers have solved the problem for myself and many others. I highly recommended them for anybody with a 2017 to 2022+ Chrysler Pacifica that has the axle nut issue!

I needed one to keep the spindle nut from backing off on a finishing mower. So far so good.

Expensive, but it worked and has not backed off since installing. Awesome.

I love nord-lock. I had to get some in a smaller size for an odd project and nordlock did not disappoint.

Perfect for bolts that come loose, I kept having turbo to manifold flange nuts come loose and blow out the gasket. I found these after doing some research, and they have worked flawlessly. 2 drift events in and the nuts didn't move at all, usually would blow out gaskets every event.

Works great

Works like they say

Great design for all applications where vibration is an issue.Will recomment to everyone.

I've used these for safety sensitive drill rig operations. work like a charm. there's a good solid "crack" if you need to loosen them for whatever reason. Worth the investment.

Look good
