SZCXDKJ4Pcs Surfboards Fin Screw Stainless Steel Fin Bolt Kit Fin Plate Replacement Accessories for Long Board, Inflatable SUP, Paddle Boards, Silver

Perfect as needed for keeping fin in place

Cheaply made, doesn’t fit any taps at all. Waste of money

These weren’t quite long enough for my board. They were decent quality though.

Spot on product….fits my fin box perfect….Bluefin US style

These are so much less hassle than the traditional screwdriver version. For a start, you don't need a screwdriver...If you usually take your fin off for transport these make life much easier. They are harder to get really tight, and at fingertight you'l find your fin vibrating at really high speed or pushing off a hard turn. There's not quite enough to grip to really do them up super-tight and so to get them really snug a small pair of pliers is best for the last half a turn. You don't need to though, and for 'good enough to get in the water' they are absolutely fine. No more asking round the car park to beg/borrow a screwdriver! At a pound each it's worth getting these just to keep in your board bag for emergencies. Great item.

Decent fin screws, very handy to have as spares as we only need one for our longboard. They are sturdy, and good quality. Great value.
