Threaded fasteners such as nuts and bolts clamp together to attach components, but the clamping force has a limit. Threadlockers serve as an adhesive to hold threaded fasteners in place at the threads. This adhesive has room to work because (an overwhelming majority of) fastener threads don't actually come together in a perfect fit, and gaps exist that threadlockers can fill.
In addition, because threadlockers fill gaps in thread contact, they can also be used to reduce corrosion, which may make the fasteners easier to disassemble with hand tools (depending on the formula used) and may even improve the sealing properties of the fastener.
A potential downside to using a threadlocker is that becuase most of them need to be applied before fastening, they can act as a lubricant and alter the amount of clamping force a given amount of torque will apply.
