The ultimate engineering solution to a problem that’s frustrated mechanics for decades. 🔧✨

Never in 50 years have I seen a nylon lock nut come loose.

Or you could safety wire it like the aerospace industry has done forever.

A nylon-insert nut is sufficient.

Nordlock, a german company

I have these on my trimax mower for the adjustment heights. Guess what? They come loose. Double nuts work better.

We use these on all kinds of heavy equipment. Expansive, but not as bad as a rental unit falling apart on the jobsite. I must say, they're very effective. Here's a rabbit hole: look into aviation fastener wire tying.

Interesting!

Screw i tighten on a car 10 years ago, still gripp permanently. It even stuck together.

Loctite already solved it long ago. But If your life depends on it, safety wire it, as is done in the aerospace industry.

Ça existe depuis au moins 20 ans !

Nord lock washer. We use them in elevator equipment Anchorage.

Very interesting.

Or Japan. Two non-loosening nuts side by side.
