The package includes an Allen wrench, with the Saitek logo printed on it. It's a rather small part, so you'd better have a back-up in your toolbox in case you loose it. Upon disassembling the joystick, I also noticed that the screws were quite small. Be careful not to loose any while you're adjusting the joystick. Even with these small counterparts, the adjustment process is relatively easy.
Every part is secured by a bolt.
In order to adjust this part, you'll need to unscrew it, adjust the part, and replace the screw. The joystick components are very well made, so they'll be safe and secure when you're ready to play. The shape of the joystick is symmetrical down the middle. This way, everything can be shifted from the left to the right side, and vice versa. The other buttons stay stationary, because they're in the same position for lefties and righties.
