TRADITIONAL FASTENING METHODS LEAVE GAPS. LOCTITE® THREADLOCKERS FILL THEM.


Mechanical locking devices such as split washers, nylon nuts and flat washers were invented to solve the common problem of loosening that happens in most threaded assemblies. The reality is that they do not maintain clamp load as assemblies “locked” with these devices often loosen under vibration, thermal expansion and/or improper torque. LOCTITE® branded threadlockers bond the thread roots and fill in all the gaps, eliminating side-to-side movement and increase the reliability of threaded assemblies by preventing fastener loosening.
