How to Install/Attach Longboard Fin? 3 Easy Ways

As a longboard player, I am very passionate about longboard activities, and feels very entertaining and enjoyable. These activities and tasks include many easy and difficult ones, as installing a longboard fin is one of the easy ones. Mounting the certified fin is effortless, and you can do it independently. 

So if you want to explore how to attach a longboard fin, the simple answer is that you have to lay the screw pin in the fin box, fix the fin into the box, and tighten the screws, and you are done. 

Have a look at the steps for the process.

What is a longboard fin?

A Longboard fin is a unique feature in skateboards or longboards specially designed to offer maximized control, stability, and performance; these are used in more giant boards where more comprehensive templates and massive fin bases are required for their best output. 

How to attach longboard fins in 3 Ways

Whether you use a longboard or the process of installing a longboard fin is the same in both. Longboard fins are featured with a no-tool screw so you can tighten it up without any instrument and use your hand. If you have different types of screws and fins, you can do it with the help of a screwdriver to make it tight. 

So the steps for attaching the fin would be the same no matter what type of fin or screw, or board you are using. 

1- lay the screw plate into the fin plate

Lay The Screw Plate Into The Fin Plate

Slide the screw plate into the fin box carefully and take it toward the front of your board. With the help of a pen or screwdriver, you can move the plate as your hand will not be fitted into the box. 

2- Insert the fin into the box

There is a pin on the back of your longboard, and you must insert this part into the center of the fin box. Slide the fin back in addition to the front of the fin that is still lifted.

Find the accurate position for the fin because it should be your priority. The more maneuverable it will be if it is farther forward the pin. 

Once your fin is attached in its right place, you can quickly push the front of the fin down towards the box. If you feel the tightness in the board, you can easily remove the fin and scratch it with the sandpaper, which makes the sides even.

3- Tight the screws

With the end of the fin, line up all the screw plates so that the screw can thread in. Move the plate around; you can do it with the screwdriver.

You can tighten the screws with your hands if you do not have a screwdriver. While if you have a classic longboard screw, you must use a screwdriver to tighten it. 

You can also consider an alternative process to attach fins to a longboard.

How do you glue Longboard fins?

Gluing fins to a longboard is a straightforward process that requires some essential tools and materials. 

Here are the tips for gluing fins to a longboard. 

Gather your materials

You will need the fins to be attached, a longboard, a fin key or screwdriver, sandpaper, and a proper adhesive. Epoxy resin is a well-known adhesive for attaching fins to the longboard.

Prepare the surface

Sand the surface on the bottom of the surfboard where you want to plan to attach the fins. This will allow the adhesive to adhere correctly to the board. 

Install the fin boxes

If your surfboard has no fin boxes, install them first. Follow the instruction manual to ensure that they are installed correctly. 

Apply the adhesive

According to the manufacturer’s instructions, mix the epoxy resin. Apply the adhesive to the base of the fins and the area on the board where the fins will be attached.

Insert the fins

Insert the fins into the fin boxes and use a fin key or screwdriver to tighten the screws. Make sure the fins are correctly aligned and secure.

Allow the adhesive to dry

Allow the adhesive to dry completely before using the surfboard. This typically takes several hours or overnight, depending on the type of adhesive used.

Check the attachment

Before taking the surfboard out into the water, check the attachment of the fins to ensure they are securely attached.

The tightness of a fin on a surfboard can affect its performance and stability in the water. Generally, fins should be tight enough to prevent movement but not so tight that they damage the fin box or the fin itself.

To ensure proper tightness, use a fin key or screwdriver to tighten the screws in the fin box. Tighten the screws until you feel some resistance, but be careful not to overtighten them, as this can cause damage to the box or the fin.

It’s also important to ensure the fin is properly aligned before tightening the screws. The fin’s leading edge should be in line with the board’s centerline, and the trailing edge should be parallel to the board’s rail.

When in doubt, it’s always better to err on the side of slightly loose rather than too tight. Fins that are too loose can cause the board to feel unstable, while fins that are too tight can put unnecessary strain on the fin box and the fin itself.

How do longboard fins work?

Longboard fins improve a longboard skateboard’s stability, maneuverability, and speed. They create resistance against the water or pavement, which helps control the board and keep it on course.

Fins are typically attached to the bottom of the longboard near the rear wheels. They can be single or multiple fins and vary in shape and size depending on the desired performance characteristics.

The size and shape of the fins can affect the board’s performance in different ways. For example, a longer fin can provide more stability at high speeds, while a shorter fin can provide more maneuverability for tricks and turns.

Fins also create drag or resistance against the water or pavement, which helps to control the board and keep it from sliding or drifting. This is particularly important when riding in choppy or windy conditions or performing high-speed turns.

In addition, fins can help to distribute the rider’s weight more evenly over the board, improving the board’s balance and stability. This is especially important for beginners still learning to maintain balance while riding.


What does a longboard fin do?

The Fin of the longboard plays an important role, as the more significant the fin more stable and controlled it will be for the longboard.
These fins are the perfect choice for surfers and beginners.

How tight should it be found in Longboards?

Fins of the longboard should be tightened to a reasonable extent, as they should not be over-tightened because they will not if the case is so.

What is the purpose of longboard fins?

Longboard fins act as a point of hold within the water so that you can easily control the movement of your board in conjunction with the water flow under the water. 


To sum up, attaching a fin to your longboard is a simple process as it is necessary for the stability and improvement of your longboard. Several types of fins are available in the competitive market, and all come with different steps with various tools. 

 So when installing a fin, you must follow the steps mentioned above with the right tools handy to get the best results.
