BZP Steel - Metric Thread

Self-locking nuts with glass-filled nylon inserts. These are designed to remain secure despite conditions of severe vibration.

Features and Benefits

Grade 8 steel, bright zinc plated

Applications

Unlike conventional fasteners, lock nuts, sometimes known as self-locking nuts, contain a plastic insert that deforms to the thread of the fastener and prevents loosening without the aid lock threading adhesive. As such, they are often used where security in fastening is required. They are useful when joining soft materials such as wood and plastics where high surface pressure might damage the material, or when there is a short clamp load. However, their principal advantage is in applications where there is a high degree of vibration. Locking nuts resist loosening over time in dynamic load conditions. As such they are often used in;

• Domestic appliances such as washers and dryers
• Industrial machinery
• Automotive industry

There are various metric sizes available:

524-304 is an M4 zinc plated self-locking nut • 524-310 is an M5 zinc plated self-locking nut
524-326 is an M6 zinc plated self-locking nut
530-393 is an M8 zinc plated self-locking nut
530-400 is an M10 zinc plated self-locking nut
530-416 is an M12 zinc plated self-locking nut
276-780 is an M16 zinc plated self-locking nut
276-796 is an M20 zinc plated self-locking nut

How to tighten a self-locking nut?

Locknuts can be applied in much the same way as conventional nuts. It is recommended to finger tighten as much as possible, and then tighten with an appropriate tool until the required torque is reached.

How many times can a self-locking nut be used?

While a locking nut can be removed in much the same way a conventional nut can, their nylon inserts deform and degrade with each use. Therefore it is not recommended that self-locking nuts be re-used if it can be avoided, as their primary characteristic- the ability to dampen vibration and stress from dynamic loads- lessens in efficacy with each use.
