Dart thread: get to know the threads in darts
Over the years, darts have transitioned from a casual pub pastime to a competitive sport that demands precision and skill. When you’ve played darts, you’ll quickly realize it’s not just about casually throwing a dart at a board and hoping for the best. Today, darts is a legitimate professional sport with advanced equipment and strategic planning.
One of the most significant advancements has been in the design of dart arrows. Back in the medieval era, players used modified arrowheads. Those days are long gone. Modern darts are meticulously engineered projectiles, crafted to exacting standards. And yes, threads play a critical role in their construction. In this article, we’ll explore where the thread is located on a dart shaft, the purpose of the dart thread, and the different types of threads used in darts.
Where is the Thread Located on Darts?
To understand where the thread is found on a dart, let’s first look at the components of a dart. You’ve likely seen, or maybe even held, a dart arrow. But did you know it’s made up of several distinct parts?
A dart generally consists of the tip, body, shaft, and flights. Given the game’s origins in Britain, it’s common to refer to these parts using English terminology.
The tip, also called the point, can be made of plastic or steel—referred to as soft tips or steel tips, respectively. Interestingly, some steel tips can be screwed onto soft darts. That’s our first dart thread! However, only soft dart tips require a thread because steel tips are usually integrated with the barrel.
The body or barrel is what players grip when throwing. It comes in various shapes and weights. The barrel connects to the shaft through a screw connection, which brings us to the second dart thread. Shafts can differ in material, weight, and length, ranging from mini to long. Depending on the material, it may also be necessary to add an O-ring to the dart’s thread for added stability.
Finally, there are the flights or fins. Their shape and material thickness are crucial for the dart’s flight path.
Why Do Darts Need Threads?
You might be wondering why darts even need threads. Why not just create the entire dart as one solid piece, eliminating the need for screw connections? Historically, darts were carved from wood without any threads on the shaft. But modern players wouldn’t accept such a basic design.
A contemporary dart is essentially an aerodynamic marvel! It’s designed to fly smoothly, maintain a stable trajectory, and be user-friendly. Each part needs to be made from materials optimized for its specific function. Threads are the best way to put these pieces together.
Another practical benefit of dart threads is customization. As darts became a respected professional sport, players’ expectations for their equipment increased. Playing style, technique, and venue all influence dart selection. Threads make it easy to swap out components, tailoring the dart to fit the player’s preferences. Additionally, if a part wears out or gets damaged, it can be replaced quickly. Some retailers even offer “build your own dart†services, allowing customers to assemble their ideal dart from individual components—a possibility only possible with dart threads.
What Thread Types are Used in Darts?
For interchangeability to work effectively, there must be some standardization. If every manufacturer used a unique dart thread, it would severely limit the player’s options. Fortunately, the industry has mostly adopted standard threads, unsurprisingly following British thread standards.
The most common thread is the 2 BA (British Association), which has an external diameter of 4.70 mm and a pitch of 0.81 mm. Another used thread is the ¼ BSF, or British fine thread, with an external diameter of 6.35 mm and a pitch of 0.977 mm.
There are two notable features regarding dart threads. Barrels from the M3 manufacturer have the thread on the outside, providing an improved weight-to-barrel diameter ratio. This design, however, is incompatible with 2 BA dart threads, requiring special shafts and tips. Another special case involves movable tips like the Powerpoint or Hammerhead. These are designed to prevent dart bounce-outs but require a particularly deep-cut dart thread. Thus, only tip and barrel combinations specifically designed for each other will work.

In conclusion, threads play a crucial role in the modern dart’s design, enabling customization and easy maintenance. Whether you're a casual player or a professional competitor, understanding dart threads can enhance your experience and help you choose the right equipment for your needs.
