The Allen wrench (hex key) for the 40v Ryobi pole saw, model RY40560 and head unit RY40051, does not have onboard storage. This was designed to clip on the saw head portion and keep the hex key close by the saw chain. Clipping it on is purposefully tight to ensure it stays on the head unit and the hex key hole is tight as well to ensure it does not vibrate out while in-use.
