Mechanical locking devices, such as split washers and nylon nuts, were invented to solve the common problem of loosening that happens in most threaded assemblies. The reality is that they don’t maintain clamp load and often loosen under vibration, thermal expansion and/or improper torque.

Why? Because mechanical devices leave gaps between the engaging threads after assembled.

By filling the gaps with threadlocker and eliminating side-to-side movement, LOCTITE® threadlockers have dramatically increased the reliability of threaded assemblies by preventing fastener loosening – a leading cause of catastrophic equipment failure. » Request your FREE sample today!
