Thread forming and cutting screws are a type of fastener designed to securely create threads in plastic, metal and other materials. They feature a sharp point and specialized threading that cuts through materials as the screw is driven into it. Thread forming screws have the capability to form strong fastening joints in a matter of seconds that can provide excellent pullout resistance.
These screws come with a variety of head styles and drive types like flat head, pan head, socket cap, countersunk, button head and Torx. Some thread forming and cutting screws also come with flanges at the head that eliminates the need for washers or nuts. These screws are available in a variety of materials like steel, stainless steel, brass and aluminum, and they can be treated to improve corrosion and oxidation resistance.
Thread forming and cutting screws are used in a wide range of applications from automotive and electronics to furniture and home appliances. In electronics assembly, these screws are used to secure circuit boards and electrical housings. In the automotive industry, these screws are often used for structural fastening of vehicle components such as dashboards, consoles, door panels and seats.
Thread forming and cutting screws offer several advantages over traditional fasteners such as bolts and nuts. For starters, the installation process is faster because it does not involve drilling a pilot hole and then inserting the fastener. Thread forming and cutting screws often achieve stronger holding power due to their design and special threading. Thread forming and cutting screws also provide vibration resistance and help reduce noise through the assembly.
When selecting thread forming and cutting screws, it is important to consider factors such as the type of material being used, the thread orientation, the size and length of the screw, the head style and drive type, and the required strength of the joint. It is also important to consider the environment where the screws will be used and the necessary corrosion protection that may be required. Taking all of these factors into consideration will ensure that the right screw is selected for the particular application.
