Work great.
Expensive but worth it in my opinion. Used on our Kioti tractor, which is bad for bolts/nuts coming loose. So far, no issues.

Hands down the best solution out there. No comparison.
These are THE be all end all solution for high heat and vibration environments. The great part about them is you are free to use antisieze as you feel as it does not compromise the locking aspect of these washers. Don’t hesitate. Just buy them.If these still don’t deal with the issue it’s probably an issue with how they are being used or you must lock wire and use these.

Every aftermarket header gets these.
Aftermarket exhaust headers are the premiere application that begs for this style of locking washers. Split washers are thick, they spread, and they skew torque numbers. I could go on about how great these work, but instead I'll say just buy them.

Holding it together
Holding my turbo manifold, turbo, and downpipe together for the past month in Arizona heat. These things are worth the money!

Awesome washers
Used these in certain areas of a race car build. Much easier to use in tight spots than standard locking hardware.
