Finally gave these lock washers a try on a trailer repair job, and they held tight through a rough test drive. The steel feels solid, and the internal tooth design really grabs the bolt. Haven’t had a single fastener back out yet.

Installed these on a shaky motor mount and everything's stayed rock solid so far. The internal teeth grip the bolt really well, and being steel they hold up without deforming.

The teeth on these washers are sharp and bite into the metal well, which gave me confidence during assembly. I used them on a small motor mount, and everything stayed tight after running it for an hour. Solid choice for vibration-prone setups.
