It has to do with the physics of the machine. Imagine the fastener being "held in place" to stop it from turning as the machine starts. With the machine starting to turn, the fastener will tighten. The last thing you want is to have the fastener become loose when the machine is running. The blade could kill or injure someone if it came off. That's why the fasteners that hold the blades on these machines always come loose when turned in the direction the blade rotates.
