Use Nord-Lock to Stop Fasteners from Loosening
We have all experienced loose screws or nuts . Whether it’s a loose fastener on a piece of machinery or on our glasses, it happens. But it doesn’t have to; what causes the loosening of fasteners and how can you prevent it? How to Prevent Fasteners Loosening To understand what causes fasteners to loosen, it is important to understand the self-locking principles of a joint. When tightening a fastener, friction is introduced in the thread and bearing areas. Maintaining this friction is the key to preventing fasteners from coming loose. External, dynamic forces, such as vibration can result in loss of friction, causing the fasteners to rotate loose if the forces are high enough. One way to prevent this is to ensure proper clamp load into the joint and use longer bolts with clamping range of at least 5x’s the diameter. This causes the bolt to act like a spring, and not lose friction when external forces act upon it. Using Nord-Lock Washers Often times joints cannot be designed...
