There are many different fastener options for metal construction today. Different options are better in certain situations. In order to have quality workmanship and all the benefits of the metal construction, the best fastener for each situation must be selected carefully.
There are two main types of fasteners. Originally, self-tapping fasteners were the only ones available. They feature unattached washers that are steel backed and bonded with rubber. Self-tapping fasteners require pilot holes being drilled in the metal. Self-drilling fasteners do not require a pilot hole and are more commonly used.
When deciding which fastener to use on a project, the substrate must be taken into consideration. Different fasteners will be appropriate for different substrates. In addition, the thickness of the material being fastened will help determine which fastener is best for the job. Different coatings and caps for fasteners are also available.
Selecting the correct fastener for each project is crucial to the final success of the project. Making the correct selection, considering the advantages and disadvantages of the different options will result in fewer problems down the road.
