LOCTITE® threadlockers offer a universal, reliable adhesive solution to an age-old problem in MRO and OEM applications. They protect bolts and threaded fasteners from working loose in the face of harsh vibration and shock, bending or environmental factors, a problem that those working with these types of assemblies have been trying to solve for many years.
However, threadlockers remain a relatively recent solution to this issue.
Threaded assemblies have long been the fixing of choice for many applications, thanks to their impressive clamp load performance. But their design means they’re susceptible to failure over time. Their ability to work themselves loose means they need to be backed up with additional locking methods that hold them firmly in place.
For years, methods of locking these assemblies meant utilizing mechanical devices. This includes threadlocker alternative products like lock nuts, washers and nylon insert nuts.
