FCS fin screws
The FCS fin screws are used to secure your surf fins in your fin plugs. With fcs’ original fin screws, you can also secure your surfboard fins in Fusion Plugs and FCS II Plugs as an extra reinforcement. This is also the advice from our shop, rely on FCS II not only on the click system but always use at least 1 fin screw per fin box. This provides extra security and prevents you from losing your fins.
Furthermore, it is important to regularly replace your FCS fin key. This prevents the corners from flattening and damaging the FCS fin screws.
