Screws and Fasteners for Construction, Garden and Assembly

Screws, Bolts and Fasteners for Construction and Garden Projects

Fasteners are used to join, secure and assemble materials and components in construction, timber work and garden projects. Depending on the job, you may need screws, bolts, coach screws, threaded rods, nuts, washers, wall plugs, hammer fixings or nails.

Intergard supplies fasteners in a variety of dimensions, materials and finishes for professional and DIY applications. To make selection easier, our fastener range is divided into five main categories.

Chipboard Screws for Timber and Wood-Based Panels

Chipboard screws are widely used for fixing timber, chipboard and other wood-based materials. They are available in different diameters, lengths, head types, drive systems and finishes.

Depending on the product, the range includes Pozidriv and TORX drive screws as well as galvanised and stainless steel versions. When selecting a screw, check the required diameter and length as well as the head, drive and finish.

View our complete range of chipboard screws.

Pozidriv or TORX Screws?

Pozidriv and TORX are different screw drive systems. Pozidriv uses a specific cross-shaped recess, while TORX uses a star-shaped drive.

Always use the correct driver bit for the screw head. A properly matched bit makes installation easier and helps prevent damage to the screw head.

Stainless Steel Screws for Outdoor Projects

Stainless steel screws offer high corrosion resistance and are frequently used for fixings exposed to moisture and outdoor conditions. This makes them suitable for many timber and garden applications when the specification of the screw matches the intended use.

There are different grades of stainless steel, so a screw described as stainless steel should not automatically be considered suitable for every environment. Always check the specified grade and product characteristics for your application.

Threaded Rods DIN 975

DIN 975 is a traditional reference associated with threaded rods. Threaded rods can be combined with compatible nuts and washers for numerous construction, fixing and assembly applications.

Intergard supplies threaded rods in different dimensions and, depending on the product, in galvanised and stainless steel versions.

Hexagon, Lock, Cap and Wing Nuts

Nuts create a threaded connection with a compatible bolt or threaded rod. The thread diameter and pitch must match the corresponding fastener.

Different designs are available for different applications, including hexagon nuts, lock nuts, cap nuts and wing nuts.

View our range of hexagon nuts.

Washers

Washers are used in many bolted connections between the fastener and the material being fixed. Depending on their design, they can help distribute the clamping force over a larger area or perform another specific function within the connection.

Select a washer with dimensions that are compatible with the bolt, screw or threaded rod being used.

Wall Plugs, Hammer Fixings and Nails

Wall plugs, hammer fixings and nails provide different methods of securing materials in construction and DIY projects. The correct type depends on the base material, the item being fixed and the intended application.

Explore our wall plugs, hammer fixings & nails.

Wall Plugs

Wall plugs are used for certain fixings where a screw alone cannot form a suitable connection with the base material. The correct plug must be selected according to the substrate, screw and intended application.

Always check the required drill diameter, installation depth and compatible screw before fitting.

Hammer Fixings

Hammer fixings provide a specific fixing method for suitable substrates and applications. Their diameter and length should be selected according to the material and the item being fixed.

Depending on the application, Intergard supplies different options including hammer plugs and window frame plugs.

Nails

Nails provide a simple mechanical fixing for a variety of timber and construction applications. Different types, diameters, lengths and finishes are available for different jobs.

Check the material and finish when selecting nails for outdoor applications or locations exposed to moisture.

Galvanised or Stainless Steel Fasteners?

The choice between galvanised and stainless steel fasteners depends on the application and the environmental conditions. Galvanising provides steel with a protective zinc coating that helps delay corrosion, while stainless steel offers high corrosion resistance through the composition of the material itself.

This does not mean that galvanised steel can never corrode or that every stainless steel grade is suitable for every environment. For outdoor, damp or demanding applications, always check the specification of the individual fastener.

What Do DIN Numbers Mean on Fasteners?

DIN references identify standardised characteristics for specific types of fasteners. Different DIN numbers relate to different designs of bolts, screws, nuts, washers and threaded rods.

Common examples within fastener ranges include:

• DIN 571: hexagon-head coach screws for timber applications
• DIN 603: carriage bolts with a rounded head and square neck
• DIN 931: hexagon bolts according to the relevant standard
• DIN 933: hexagon bolts or screws according to the relevant standard
• DIN 975: traditional reference associated with threaded rods

Not every fastener is necessarily manufactured to a DIN standard. Always check the specification of the individual product.

How to Choose the Right Screws, Bolts and Fasteners

Start by identifying the materials you need to join and the conditions in which the fixing will be used. You can then select the appropriate fastener type, dimensions, material and finish.

1. Identify the materials. For example timber, metal or another substrate.
2. Determine the application. Indoor, outdoor, construction or garden use.
3. Choose the fastener type. Screw, bolt, coach screw, threaded rod, wall plug, hammer fixing or nail.
4. Determine the diameter and length. Match the dimensions to the connection.
5. Select the material or finish. For example galvanised steel or stainless steel.
6. Check the head and drive. For example hexagonal, Pozidriv or TORX.
7. Check the relevant standard. Where the project requires a particular specification.
8. Use the correct tools. Select a compatible driver bit, spanner, socket or other installation tool.

Fasteners for Timber and Garden Construction

Outdoor timber structures require fasteners suited both to the connection and to the environmental conditions. Fences, posts, pergolas, decking and other garden structures may require different screws, bolts or other fixings.

Do not choose a fastener based on length alone. Diameter, thread, head design, material and finish can all be important when selecting the correct fixing.
