Choosing the right fastener to construct your storage building should be top priority. When it comes to metal building projects, the nuts and bolts you choose are essential to the structure’s integrity. If your panel manufacturer hasn’t specified which ones should be used, then you must select them based on your storage building’s specifications in order to meet code requirements.

Many factors determine the best-suited screws and bolts for your application. Even if many different fasteners can work for your building, some can perform better than others, based on your specifications. Here are four of the most critical factors to consider relating to the proper selection of the required fastener.

Metal Panel Gauge

In order to resist forces, you must know the configurations and metal gauge of your panels. This information will define which head diameter you should be choosing.

Girt Gauge

The thickness of the steel girts, also known as a Sheeting rail or Perlin when used in roofing, that your fasteners will be installed in will narrow down the types of diameters and point configurations that you can use. It must be fastened through the girt without problems. So when choosing the right one for your project, measure the thickness of the girts first.

Girt Spacing

The surface area of the panel that will be dependent on their ability to resist negative forces is determined by the spacing of both the fasteners along the girts and the girts themselves. Negative forces can damage your building’s integrity, and thus, they should be avoided by first calculating the girt spacing or referencing your building design specifications.

Design Wind Loading

The design wind loading is going to help determine the forces that may be exerted on your panels. This loading will define the minimum strength requirements that are needed for maximum performance and reliability.

Other Factors

Although these four factors are the most critical to consider while constructing a storage building, other aspects must be taken into consideration as well.

Material

The material you choose will have a direct impact on the resilience and strength of your building and it will be largely based on function and your durability expectations.

Head Shape

When it comes to metal walls, there are two main head shapes to choose from—hex head or pancake. Hex head is more stable and is most often used for concealed panels and exposed applications, while pancake heads are most often used when there is limited space in the panel because they have a recessed configuration. Recessed head designs are also important where water penetration can be an issue.

Length

The total thickness of your components will define the necessary length that you’ll require. It is determined by adding up the total of the length of the threaded body, the length of the unthreaded drill point, and the unthreaded shank under the bearing surface.

Coating

Especially when it comes to outdoor storage buildings, choosing the right coating is going to be essential. Its purpose is to protect the screws and bolts from corrosion caused by the elements. With wind, rain, and snow pummeling down on your building, you’re going to need a protective coating to ensure durability.

Fasteners are an essential part of your storage building project. Without the right fastener, both your panel system and your fastener can fail, putting your building, your stored products, and even your own safety at risk.
