Frequently Asked Questions
Are lock washers effective at preventing loosening?
Modern engineering testing shows split lock washers can actually reduce clamp load under vibration. For critical applications, use nylon insert lock nuts or thread locker (Loctite). Tooth lock washers (internal/external star) typically perform better than split washers in vibration-prone applications.
