+#### Pin
+
+The pin slides into a groove in the US Box fin slot, allowing the fin to move forward or backward to adjust the fin's position for different conditions or board feel.
+
+US Box require a pin of diameter 4.76mm (3/16 inch) per L 14.28 mm (9/16inch) 
+
+### Screw
+
+The screw for securing single fins is often 10-32 x ¾” (or 5mm x 19mm).
+It's usually a slotted screw designed to go through the fin and into the square plate.
