In most fabrication processes and for Original Equipment Manufacturers (OEMs) finding the right materials for the job is important to speed up production while also helping to decrease the costs. This also true for construction companies and contractors.
Selecting the right fastener for the job may mean taking a closer look at the options. For many construction and fabrication jobs, self tapping sheet metal screws may be an ideal fastener option for several important reasons.
To get a better understanding of the use of these screws, taking a closer look at the design and the function will be essential.
Sheet Metal Screws
Unlike machine screws, which require a hole to be tapped, self tapping sheet metal screws do not require a pre-tapped or pre-threaded hole. This means that the installer doesn’t have to pre-drill or tap the hole. Instead, the sharp threads on the base of the screw create the hole and also cut the threads as they are installed.
This is what self-tapping indicates, the ability to create the thread needed to allow for installation of the screw without the need for the separate operation of drilling a hole. As sheet metal screws are used to attach metal to metal, this saves time as well as limits the number of tools needed on any job site.
Easy Identification
The unique shape of self tapping sheet metal screws makes them easy to identify. The head configuration and the specific type of screw from Phillips to flat or those that will be installed with a nut driver are all possible, similar to other types of fasteners.
The tip will be the key identifier. The threads will run the length of the screw with the last area of the tip without threads but with a cutting tip, similar to a drill bit. Depending on the length of the screws this cutting area will be longer or shorter, allowing for the self-tapping of the metals.
