Lock Nuts from Fabory to prevent vibration loosening

Lock nuts, also known as locking nuts, are fasteners designed to prevent loosening under vibration and torque. They achieve this by various means, such as incorporating a nylon insert or distorted threads, which provide resistance when mated with a bolt or screw. These mechanisms ensure that the nut remains securely fastened even in dynamic conditions.

Lock nuts are essential in applications where movement or vibration might cause standard nuts to loosen over time. They are widely used in machinery, vehicles, and structures that experience regular or significant vibrations. Their primary function is to ensure a secure fastening that does not degrade even under dynamic conditions, thus maintaining the integrity and safety of the assembly.

Several factors are crucial when selecting lock nuts: the material, size, type, and locking mechanism. Common materials include different steel and stainless steel grades, each offering varying degrees of strength and corrosion resistance.
