Threaded Rods, Nuts & Washers – Galvanised & Stainless Steel

Threaded Rods, Nuts and Washers for Secure Connections

Threaded rods, nuts and washers are used to create a wide range of threaded connections in timber, steel and other suitable construction materials. Typical applications include timber construction, metalwork, installation work, fencing and garden structures. The correct combination depends on the connection design, thread, dimensions, material and conditions of use.

At Intergard you can choose from threaded rods, nuts and washers for different types of fastening and assembly work.

DIN 975 Threaded Rods

A threaded rod is a long metal rod with a continuous thread along its length. This allows compatible nuts to be positioned at different points along the rod. Threaded rods are used for applications such as through-connections, suspension systems, mounting arrangements and anchoring.

DIN 975 remains a widely recognised traditional reference for continuously threaded rods. For technically demanding applications, always check the current product specification and the requirements of the individual project.

What Are Threaded Rods Used For?

Threaded rods are particularly useful where a long, through-bolted or adjustable threaded connection is required. Because there is no fixed bolt head, nuts can be fitted at one or both ends or at other suitable positions, depending on the connection design.

Typical applications include:

• through-connections;
• timber and metal structures;
• suspension systems;
• mounting and installation work;
• anchoring applications;
• fencing and garden structures.

Galvanised DIN 975 Threaded Rods

Galvanised threaded rods have a zinc coating that helps protect the underlying steel against premature corrosion. Galvanising does not make steel completely rust-proof. Suitability for a particular application depends on the finish and the environmental conditions to which the threaded rod will be exposed.

Stainless Steel DIN 975 Threaded Rods

Stainless steel threaded rods offer a high level of corrosion resistance and are often selected where moisture or weather exposure is an important consideration. Not every stainless steel grade is suitable for every environment, so always check the individual product specification for the intended application.

Nuts for Threaded Rods and Bolts

Nuts are screwed onto compatible threaded rods or bolts to create and secure a threaded connection. For the connection to work correctly, the thread, nominal diameter and other relevant dimensions of the nut and threaded fastener must be compatible.

Our nuts range includes different designs for a variety of fastening applications.

Which Nut Do I Need?

Choose the nut first according to the diameter and thread of the bolt or threaded rod. The application then determines which type of nut is most appropriate. Different nut designs perform different functions within a threaded connection.

Before installation, always check that the nut and threaded rod or bolt have compatible threads and dimensions.

Washers for Threaded Rods, Nuts and Bolts

Washers are positioned between a nut or bolt head and the surface of the material being fastened. Depending on the washer type and connection design, a washer can increase the bearing area and help distribute the applied load over a larger surface.

A washer is not automatically required for every threaded connection. Whether a washer is needed, and which type should be used, depends on the materials, connection design and technical requirements.

Galvanised or Stainless Steel Threaded Rod?

The choice between galvanised steel and stainless steel depends on the application, environmental conditions and required level of corrosion resistance. Each material provides different characteristics.

Galvanised Steel

Galvanised steel has a zinc coating that helps protect the underlying steel and delay corrosion. The durability of this protection depends on factors such as moisture, weather exposure and other environmental conditions. Galvanised steel should therefore not be regarded as completely rust-proof.

Stainless Steel

Stainless steel provides a high level of corrosion resistance through its material composition. It is commonly selected for applications where moisture or weather exposure is an important consideration. The appropriate stainless steel grade depends on the specific environment and intended use.

What Does DIN 975 Mean for Threaded Rod?

DIN 975 is a traditional designation that remains widely used in the fastener trade for continuously threaded rod. It provides a familiar reference for identifying this type of fastener.

A DIN reference alone does not mean that a threaded rod is automatically suitable for every structural or heavily loaded application. Material, dimensions, mechanical properties and the technical requirements of the project must also be considered.

How Do You Choose the Correct Threaded Rod Diameter?

The required threaded rod diameter depends on the design of the connection and the loads for which it has been specified. Nuts and washers must also be selected in sizes that are compatible with the chosen threaded rod.

Before ordering, check:

• threaded rod diameter;
• thread and thread pitch;
• required length;
• material: galvanised steel or stainless steel;
• compatible nuts;
• compatible washers;
• indoor or outdoor use;
• technical requirements of the connection.

How to Use Threaded Rod with Nuts and Washers

Depending on the connection design, threaded rod can be passed through the components being joined and secured using compatible nuts. Where required by the connection, suitable washers can be positioned between the nut and the material.

1. Determine the required diameter and length.
2. Check that the threaded rod is suitable for the application.
3. Select nuts with a compatible thread.
4. Select suitable washers where required.
5. Position the threaded rod according to the connection design.
6. Fit the washers and nuts where required.
7. Tighten the connection using suitable tools.
8. Check the completed connection after installation.

For structural or safety-critical applications, always follow the relevant technical specifications, installation instructions and engineering requirements for the project.

Threaded Rod for Timber, Fencing and Garden Structures

Threaded rod can be used for various connections in timber structures, fencing and other garden construction projects. Its continuous thread allows compatible nuts to be positioned according to the requirements of the connection.

For outdoor applications, the choice of material is particularly important. Moisture, weather exposure and contact between different materials should all be considered when choosing between galvanised steel and stainless steel.
