The images show a high-tensile threaded bolt with a distinct splined (serrated) shoulder just below a large, rounded pan head.
The Splines (image_2.png): These bite into the metal of the wheel hub or brake drum when pressed in from behind, preventing the bolt from spinning when you torque down the wheel nuts.
The Dimensions:
Looking at image_2.png, the splined shoulder has a diameter of roughly 22mm to 23mm.
Looking at image_3.png and image.png, the threaded portion is quite substantial, likely an M22 thread size, measuring roughly 95mm in length.
