Self Drilling Screws for Metal – What You Need to Know Eddie Burlem, October 4, 2024October 4, 2024 Fastening materials to metal is commonplace on the job site. However, this means that you’ll need a special type of screw to get the job done: Self-drilling screws for metal. We’ll cover what you need to know about self drilling screws for metal below. But first, let’s talk about the differences between screws for metal and other materials. What’s the Difference Between Screws for Metal and Other Screws? Self drilling screws for metal have one primary differentiating factor: They don’t require a pilot hole to fasten. Since a pilot hole isn’t necessary, screws used for metal need to be able to create their own holes, which is where the name “self-drilling screws” comes from. The tips of these screws typically have a very sharp edge with the ability to cut through metal and create a hole. The threads are also slightly different as well, with metal screws using tighter and sharper threads. Compare this to a wood screw, for example. Wood screws often don’t have nearly as sharp of a tip while also using looser threads. In some cases, screws used for wood have a threadless shank near the head.While each screw should only be used for its intended purpose, in a pinch, metal screws can be used to fasten other materials. However, the reverse is not possible. Only metal screws can be used to fasten metal. How Are Self-Drilling Screws For Metal Used? Sheet metal Sheet metal is one of the most common applications for self drilling screws. In this case, using self-drilling screws helps speed up the production process when sheet metal is used for framing and other projects. This includes industries such as the automotive industry, furniture, and more. Roofing Another common use for self-drilling screws, the metal roofing process can be sped up tremendously by using Architectural Roof Clip Fasteners used for metal roofing are typically designed with a washer that forms a tight seal when fastened. Framing Self-drilling screws designed for framing are able to cut straight through even heavy-duty metal studs. In most cases, they have special heads that allow for more holding strength at the cost of driving torque. If drilling through dissimilar metals (steel and aluminum) always use Dril-Flex structural self drilling screws. Are All Self-Drilling Screws Made For Metal? While the majority of self-drilling screws are made for metal, there are other uses for self-drilling screws. For example, self-drilling drywall screws are an option for putting up sheets of drywall. They have a countersunk head that fits properly into the drywall without the risk of tearing the paper. They’re also strong enough to be fastened to both wood and metal studs. Self-drilling screws are even used (and preferred) in the medical field since they can be fastened quicker than other types of medical screws. They can be used for orthopedic surgery, tissue repair, muscle repair, and organ replacement.
