RS PRO BZP Steel 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. The nut is made from grade 8 steel with a bright zinc plating, for durability and environmental resistance over a long period of use.

Features and Benefits

• Locking nuts for heavy-duty applications
• Glass-filled nylon inserts.
• 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.

RS Pro Nylon Insert Nuts Zinc Plated

The RS Pro zinc plated locking nuts have a nylon insert. The nuts have been designed to remain secure despite severe vibration. Having a nylon insert makes the nut better at sealing the bolt thread against leaking water, oil and other liquids.
When you insert the mating bolt into the nylon insert, the thread from the bolt compresses the nylon.

Note

If Zinc plated is not what you are looking for, we have the nylon insert nuts in A2 and A4 stainless steel.

Greater resistance to vibrations and torque
Mild steel grade 8.8
Retains locking ability up to 250°C
Resistant to organic acids, solvent, oil and mineral salt
360° seal
Available from M5 to M20

Typical Applications

Used by builders, DIY enthusiasts, joiners and Roofers.

RS PRO A4 Stainless Steel Dome Nuts

From the trusted RS PRO brand, these dome nuts are ideal for applications where it is desired to hide or cover the end of a projecting screw thread. The dome shape can eliminate the possibility of snagging edges, which is ideal for capping off flexible threaded rods. The dome has a hexagon flange which is ideal for both hand and tool tightening for the application of appropriate torque. This flange also may eliminate the need for a washer to distribute the pressure of the nut.

The dome nut is made of A4 stainless steel, marine-grade stainless steel that has excellent resistance to corrosion and is suitable for almost any environment. Components made from A4 stainless steel are suitable for use in surgical and underwater applications.

There are a variety of metric sizes available

• 248-4450 is an M3 A4 Stainless Steel dome nut
• 248-4466 is an M4 A4 Stainless Steel dome nut
• 248-4472 is an M5 A4 Stainless Steel dome nut
• 248-4494 is an M6 A4 Stainless Steel dome nut
• 248-4501 is an M8 A4 Stainless Steel dome nut
• 248-4517 is an M10 A4 Stainless Steel dome nut
• 248-4523 is an M12 A4 Stainless Steel dome nut

Features and Benefits

• Dome nuts with hexagonal flange
• Metric sizes
• DIN6923
• A4 grade 18//8 stainless steel (Type 316 S16)

Applications

Dome nuts, sometimes called acorn nuts, are a versatile fastener used for aesthetic and practical reasons wherever a bare screw thread is a concern. Unlike using standard nut fixings, a dome nut completely covers the end of a screw. As such, it can be used in lieu of, or on top of, fastening nuts. These domed nuts can be used to cap threaded bars or make sure a surface is snag-free.

What are the benefits of stainless steel?

Stainless steel is useful for more than just a visual purpose. The main highlight would be the superior corrosion resistance, stopping unwanted issues like rusting. High heat resistance is also a big benefit, due to the way stainless steel is created, it can withstand an incredible amount of heat as opposed to a screw or socket made from standard steel. The only possible issue may be cost, however, a reliable and durable material will not only increase the longevity of the application, but also the sustainability.
