Additional Information

A lock nut, also referred to as locknut, locking nut, and self-locking nut, is a kind of fastener that used to secure bolted joints and resist loosening under vibration and torque. After inserting a bolt through the objects, a lock nut can be twisted onto the end of the bolt (from the backside of the object), in conjunction with the bolt and secure the whole part. The lock nuts can prevent loosening either utilizing the friction or some positive locking device, depending on its structure and materials. The installation procedure is basically the same as normal nuts.
