Screws are a type of fastener and play an important role in tying two entirely different things together for commercial, industrial, and residential applications. While there is a wide range of screws that come in various sizes and shapes for multiple applications, metal roofing screws have their own role to play. These screws are used to attach metal panels to various building structures. Roofing screws come in various sizes, designs, and materials. Each kind is specifically designed to serve a particular purpose. These screws are selected by the builders and building owners to achieve the end results. However, you only have the ability to select the right screws once you have a basic understanding of the benefits and workings of the various types. We have put together some useful details about metal roofing screws to help you understand the purpose of these fasteners and use these screws for their appropriate applications. Further details are given below:

Materials used for Manufacturing of Metal Roofing Screws:

Metal roofing screws are made up of various metals and combinations of metals for different applications and results. Generally, the standard fastener is made up of a carbon steel base with a plating or coating of corrosion-resistant material for protection. There are long-life fasteners that offer optimum resistance against corrosion. These fasteners are made up of stainless and are ideally used for the attachment of aluminum panels to building structures with wooden or metal substrates. It should be noted that screws made up of stainless steel are not capable of drilling a steel panel or piercing it consistently on their own. Bimetallic fasteners are required to attach a steel panel for complete corrosion resistance. Bimetallic fasteners for both wooden and metal structures are available in the market. One thing that should be mentioned here is the head and shank of these fasteners are made up of stainless steel, however, the point is made up of carbon steel that allows for faster penetration into the steel panel and drilling into the wood and metal substrates.

 

Why are Screws Preferred Over Nails?
In the old days, nails were used to attach the metal panel to post-frame structures. Over time, washers were also used with nails for stronger weather tightness. However, installers were looking to enhance the holding power and weather tightness of the attachments using a single fastener. This is where threaded fasteners with sealing washers evolved. These fasteners were specifically designed to hold wooden attachments strongly. Over the years, these fasteners have evolved a lot to offer maximum benefits including ease of installation, a faster installation process, enhanced holding power, pull-out values, optimum corrosion resistance, and even aesthetics. With the application of a screw gun, these screws can be installed considerably faster as compared to the process of hammering nails. Additionally, the use of roofing screws for the purpose of roof attachments provides improved overall control on the finished results. Including proper depth setting and improved sealing against penetration of water. It is a well-known fact that holding power or pull-out strength of screws is far better than any type of nails. In the case that there is a requirement, you can easily pull out these screws which is quite challenging in the case of nails.
