FCS screws are used to secure fins to a surfboard. The standard screw size for FCS screws is 10-24 x 5/16, and they require a 3/32 Allen key. The screws are made of stainless steel and are available in packs of 12. It's important to note that FCS and Futures Fin screws have different threadings, so using the wrong type of screw can result in stripped fin boxes.

What You'll Learn
FCS grub screw size: 10-24 x 5/16″
The FCS grub screw size of 10-24 x 5/16″ is a standard size for surfboard fin screws. The original FCS system uses two grub screws, one for each tab, to keep the fins in place. These screws have a thread size of 10-24 and a length of 5/16". They require a 3/32 Allen key to tighten and loosen.
You can purchase packs of replacement grub screws for FCS fins online, either directly from FCS Australia or from third-party retailers such as True Ames, Surftech, and Amazon. These packs typically contain between 6 and 12 screws and may include a fin key or Allen key.
It is important to maintain your surfboard fin screws properly to ensure they last longer. This includes periodically rinsing them with freshwater, avoiding over-tightening, and using a correctly-sized key or driver to prevent stripping the head.
If you encounter issues with your fin screws, such as rust or stripping, you can try to remove the stuck screw by soaking it in penetrating oil or gluing a sacrificial fin key or Allen wrench to the screw and then removing it. In some cases, you may need to fill the screw hole with epoxy and drill through the center to create a new thread for the replacement screw.

FCS grub screws are different from Futures grub screws
When it comes to surfboards, the type of screws used to secure the fins is crucial. FCS and Futures are two popular brands of fin systems, and while they may seem similar, their grub screws have distinct differences that surfers need to be aware of. Here are the key reasons why FCS grub screws are different from Futures grub screws:
- Thread Design: The most significant difference between FCS and Futures grub screws lies in their thread design. While both types of screws have a thread size of 10, the pitch of the threads differs. FCS grub screws have a thread pitch of 24, indicated as 10-24, while Futures grub screws have a pitch of 32, denoted as 10-32. This difference in thread pitch means that the threads on FCS and Futures screws are cut differently and are not interchangeable. Mixing them up can lead to stripped fin box threads, as the wrong type of screw can damage the threads in the fin box.
- Number of Screws: The original FCS system typically uses two grub screws per fin to secure each tab, whereas Futures fins usually feature a single hex head grub screw that fastens the fin into the box. This difference in the number of screws per fin is an important distinction when it comes to installation and replacement.
- Length and Dimensions: FCS and Futures grub screws also differ in their length and dimensions. FCS grub screws are 5/16" long, while Futures grub screws are slightly longer at 1/2". Additionally, the hex heads of Futures grub screws are designed to accommodate a 3/32 Allen key, while FCS grub screws are compatible with the same size Allen key (3/32).
- Compatibility: Due to the differences in thread design and dimensions, it is essential to use the correct grub screws for your fin boxes. FCS screws are specifically designed for standard FCS fin plugs and should not be used with Futures fin boxes. Conversely, Futures grub screws are meant for Futures fins and should not be used with FCS fin systems. Using the wrong type of screw can result in stripped threads, making it challenging to secure the fins properly.
In summary, while both FCS and Futures grub screws serve the same purpose of securing surfboard fins, they are not interchangeable due to differences in thread design, the number of screws per fin, and their physical dimensions. Surfers need to be mindful of these distinctions to avoid damaging their equipment and ensure a secure and proper fit for their fins.

FCS screws are threaded differently from Future Fins Box screws
When it comes to surfboards, fin systems are a critical tool that offers stability, drive, and manoeuvrability. There are two main brands when it comes to fin boxes: FCS and Futures. FCS has two core versions, the original FCS, introduced in 1995, and the improved FCS II, released in 2013. Futures, on the other hand, was founded in 1996 and has stuck with a single tab design since.
FCS fins are designed with two tabs that are secured to the board with a special set of screws. The original FCS system uses two grub screws, one for each tab. Each screw has a 10-24 thread and is 5/16" long. These screws are compatible with standard FCS fin plugs.
Futures, unlike FCS, uses a single-tab system for its fins. Each fin is secured with an angled screw. Due to the single tab design, the fins have a firmer connection to the board, resulting in less flex and increased strength. The Futures grub screw has a 10-32 thread and is 1/2" long.
It is important to note that FCS and Futures fin screws are threaded differently. Using the wrong screws will strip your fin boxes. Therefore, it is crucial to use the correct screws for your fin system.

FCS screws are stainless steel
FCS screws are made of stainless steel to prevent rusting and corrosion, which can occur with other metals when exposed to saltwater and air. Stainless steel is known for its durability and resistance to oxidation, making it an ideal material for surfboard screws that will be in constant contact with saltwater.
The use of stainless steel for FCS screws ensures that surfers don't have to worry about their screws rusting over time, which could lead to a loose or detached screw and potentially impact the performance and stability of their surfboard.
Additionally, stainless steel is chosen for its strength and ability to withstand the forces exerted on the screws during surfing. The material can handle the pressure and stress without deforming or breaking, ensuring the screws remain securely in place.
The standard size for an FCS grub screw is 10-24 x 5/16", and they are designed to fit into FCS fin boxes. These screws are commonly used to secure surfboard fins in place, and their small size makes them ideal for the fin systems.
FCS stainless steel screws are available in packs of 12 or 20, making it convenient for surfers to have spares on hand in case of loss or damage. These replacement screws are easy to find and purchase through online retailers or local surf shops, ensuring that surfers can quickly get back on the water if they encounter any issues with their equipment.
By using stainless steel, FCS screws provide a reliable and durable solution for surfboard fin systems, ensuring that surfers can focus on enjoying their time in the water without worrying about the condition of their equipment.

The screws are threaded and can be tightened or loosened using an Allen key. The specific size of the Allen key required depends on the type of screw, but it is typically a 3/32 Allen key for FCS screws. It is important to note that FCS and Futures Fin screws have different thread patterns, so using the correct type of screw for your fin system is crucial to avoid stripping the fin boxes.
When purchasing FCS screws, they typically come in packs of 12, which can be useful for replacing lost or damaged screws. These screws can be found at local surf shops or hardware stores, or online through retailers like Amazon.
To prevent issues with your FCS screws, it is recommended to maintain them by rinsing them with freshwater and avoiding over-tightening. Additionally, using a key/driver that fits snugly can help prevent stripping the head of the screw.
