All types of fasteners are commonly used in the construction industry as there is a constant need to fix objects and items together to create structures. They are only used when joining materials which have already had a hole drilled through them, as they cannot create the hole themselves in the same way that a screw can. They are used in a variety of construction projects. You might use them to fix pieces of wood together as part of a timber frame, for example. The type of fastener that you will need depends on the specifications of the projects. There are many fasteners that are uniquely suited to certain jobs. For example, rail nuts are uniquely suited for use in the rail industry as they are resistant to extreme vibration. You can often consult nut suppliers for advice and recommendations on what type of fastener will suit your project.
