The SaeboStep Eyelet Hook Kit comes with three different screw lengths to secure the hook to your shoe. Be sure to select the appropriate screw length for your shoe. Each shoe is different and the material around the eyelet can be thicker on some shoe designs. It is important that the screw is long enough to thread into the brass fitting on the underside of the eyelet hook to secure it properly. If your eyelet hook has popped off, you may need to select the next longest screw. Next, make sure you tighten the screw using the Allen wrench provided in your kit.
