Self-locking nuts DIN 985 incorporate a nylon washer inside and are designed to join two elements exposed to vibration or movement, preventing the bolt from loosening over time. They provide a fixed grip on the bolt, preventing it from loosening. This type of nuts are very useful in the field of mechanics and construction where the elements are exposed to continuous movement and vibration.

What are the advantages of self-locking nuts?

DIN 985 self-locking nuts have a number of advantages to ensure a consistent and durable fastening. Their main function is to prevent the bolt from loosening due to movement or vibration in the environment. This type of nut is frequently used in the machinery, automotive and construction sectors. These are their main advantages:

No need for readjustment. Self-locking nuts do not require periodic readjustment of the bolts, which saves time and effort.
Simple installation. They are easy to apply and remove. They are ideal for jobs where regular maintenance is required.
Space saving. Self-locking nuts take up less space than other locking devices, making them ideal for fastenings where space is limited.

Self-locking nuts: types and characteristics

Self-locking nuts have a series of characteristics and functionalities depending on the model.

Self-locking hexagonal nuts: these nuts incorporate a spring washer which exerts pressure on the bolt thread and the fastening surface. It is important to observe the recommended tightening torque, otherwise the washer may be damaged and its locking capacity reduced.
Conical self-locking nuts: have a conical section at the bottom which is pressed against the fastening surface, generating a pressure that prevents the bolt from loosening over time.
Tall self-locking nuts: these are taller than other self-locking nuts and, thanks to the slots at the top, they fit tightly against the bolt, exerting uniform pressure.
