Eliminating Fastener
Loosening.
Preventing Failure.
TRADITIONAL FASTENING METHODS LEAVE GAPS.
LOCTITE THREADLOCKERS FILL THEM.
Mechanical locking devices (such as spring washers, nylon ring nuts, etc.) were invented to solve the
common problem of loosening that happens in most threaded assemblies. The reality is, however, that
they don’t maintain clamp load as assemblies “locked” with mechanical devices often loosen under
vibration, thermal expansion and/or improper torque. Why? Because mechanical devices don’t fill the
gaps between the engaging threads. By bonding the thread roots and filling all of the gap, 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.
BENEFITS
Lock against self-loosening caused by Prevent galling & seizing – allowing for
vibration and thermal expansion reliable disassembly
Maintain clamp load Reduce inventory costs – one bottle for
all fastener shapes/sizes.
Seal against corrosion and leakage
