Only 0.13" thick. They also have a keyed notch which is either for locking action (nuts are a tight fit on the bolt/shaft) or possibly in case clearance/indexing is needed when installing on a shaft, notch is roughly 0.2" wide at the thread end and extends to a radiused end roughy 0.16" in length (see pics for how it looks).
