Review on Santa Barbara Surfing SBS - Hassle-Free Stainless Steel Fin Screw for Longboard and SUP - Convenient 2 or 3 Pack Selection by Shawn Pollock

I use this fin screw on a few of my boards that need them. They work well, but make sure you button them up nice and tight. When first tightening I didn't apply too much torque because I didn't want to overload the fin box. Luckily I realized that the screw fell to the ground while unloading the board and wasn't lost. When I reinstalled it I made sure it was much better tightened. I also did the same when installing it on my SUP and now it seems to be holding up well. It's a nice plus that you don't need a screwdriver to adjust it, but I still never adjust the position of the fin.
