Threads are a defining characteristic of screws. Consisting of spiraling ridges, they are designed to generate a clamping force. When you drive a screw into an object, the threads will press against the inner walls of the hole, thereby securing the screw in place. There are different types of screws, however, such as twinfast screws.
What Are Twinfast Screws?
Twinfast screws are mechanical fasteners that feature two thread paths. Traditional screws, on the other hand, typically feature a single thread path: they begin with a helical ridge near the tip that wraps around the shank toward the head. Twinfast screws are different in the sense that they have two thread paths rather than just one.
Twinfast screws have the following features:
- A sharp point
- A head with a drive recess/type
- Two thread paths running up the shank
What Are Twinfast Screws Made Of?
Common materials in which twinfast screws are made include stainless steel and carbon steel. Carbon steel twinfast screws are commonly used for drywall and chipboard installation. They offer high tensile strength, allowing them to withstand heavy loads. Stainless steel twinfast screws are better suited for outdoor or humid environments, as they offer a superior level of protection against rust and corrosion.
Why They Are Called Twinfast Screws
Twinfast screws receive their namesake from their fast drive speed. Normally, a single revolution will move a traditional screw forward through an object at a distance equal to the screw’s thread pitch. Twinfast screws, though, advance farther per revolution. They can essentially advance through objects twice as fast as their traditional counterparts.
Two Thread Paths = Two Starting Points
Because they have two thread paths, twinfast screws have two starting points. The beginning of each thread path is a starting point. It’s an area where the screw enters the object in which it’s driven. During installation, the two thread paths will both cut into the object.
Why Use Twinfast Screws
One of the main advantages of using twinfast screws is faster installation. As previously mentioned, they advance twice as fast as traditional screws. If you’re doing a large project that requires dozens or even hundreds of screws, this can save you a substantial amount of time.
Not only are they faster to install, but twinfast screws also require less torque. The dual-thread path design reduces the amount of force required to drive them into objects. Whether you’re using a power drill or a manual screwdriver, you’ll have an easier time with twinfast screws.
