RS PRO, Bright Zinc Plated Steel Locking Nut, DIN 6926, M5

RS PRO BZP Self-Locking Nut

From the trusted RS PRO brand, these lock nuts contain a nylon insert for safe and secure fastening. They are designed to remain secure despite conditions of severe vibration. They have a large flat integrated washer which allows for load distribution against a surface, and have a hexagonal structure for ease of screwing and unscrewing with a spanner or appropriate socket. The nut is made from grade 8 carbon alloy steel with bright zinc plating, for durability and environmental resistance over a long period of use.

Features and Benefits:

• DIN6926 Grade 8 steel, bright zinc plated


• Self-locking due to nylon insert


• Plain faced flange

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.They are commonly used in applications where a secure fastening is required or 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 and because of this, they are often used in:

• Domestic appliances such as washers and dryers


• Industrial machinery


• Automotive industry

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.

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.
