What are the Different Types of Threads on Screws?

Screws are hardware components that are used to conjoin two or more parts, featuring external threading that allows for materials to be fastened and held together with ease. Capable of self-threading, the screw will cut its own thread into a component when driven, pulling materials together to prevent the chance of the fastener being pulled out. Depending on the type of materials that are being worked on, alongside other factors, there are a few common types of screw threads that may be chosen from. To ensure that you choose the right screw thread for your needs, we will discuss some of the most widely used variations.

Woodworking

When one is working with wooden materials, woodworking screws are your best choice. Typically, such components feature tapered shanks and sharp threading, allowing them to bore into wood with ease.

Drywall

Drywall screws are specifically intended to be used on drywall surfaces, though they may also act as woodworking screws when needed. When working with drywall, it is crucial that one determines the screw size, length, and weight that is best fit for a given type of wall or ceiling to ensure that damage does not occur. For hardwood and metal studs, drywall screws with fine threading and twinfast are used. Meanwhile, soft wood and wood studs are better paired with screws that have coarse threads.

Machine

Machine screws are optimal for conjoining metal objects and surfaces, serving as one of the most common variations. Generally, machine screws may be paired with tapped holes or nuts that exhibit a matching diameter and thread count.

Security

When one wants to implement a fastening solution that cannot be tampered with, the best choice of hardware is a security screw. Unlike other common variations, security screws are devoid of an operable head, meaning that they require special tools to be installed or removed.

Self-drilling

Self-drilling screws may be procured in magnetic or non-magnetic variations, often being used for metal-to-metal or wood-to-metal projects. Roofing screws are a common type of self-drilling screw that provide metal-to-metal fastening for installing roofing and wall panels onto steel framing.

Self-tapping

Self-tapping screws may create their own thread in a material when they are installed, creating a matching thread that corresponds to their external threading. Self-tapping screws may come in various subtypes such as sheet metal screws, allowing them to be used for diverse applications. If corrosion resistance is necessary, a screw such as a self-tapping deck screw may be beneficial.

Beyond such types, there are many other variations that one may use to efficiently get the job done. When shopping for various solutions, it is also important to consider the diameter, pitch, crest, thread angles, and coarseness that may be needed for a specific project. Lastly, one should also take into consideration the materials that they are working with in order to prevent damage to fasteners or working materials due to galvanic corrosion, hardness, etc. When you are ready to begin sourcing the various fasteners that you need for your given needs, look no further than ASAP Aviation Hub.
