Simply put, a lock nut is a fastener designed to prevent loosening under vibration, shock, and dynamic loads.

The issue with standard nuts is that they gradually loosen due to micro-movement between threads in vibrating or variable-load environments, leading to joint failure.
Lock nuts solve this through specialized designs that permanently increase thread friction, creating a “mechanical lock” to maintain a secure connection.

It’s not about how tight you fasten it — it’s about the nut’s built-in resistance to vibration.
Our nuts are widely used in critical applications like aerospace and automotive industries, where failure is not an option.
