Guy there is no way one will go un-noticed in the unlocked position. It would be floppin and hangin all out in the open at you. Since these are adjustable, you would have to orient each one the same way and adjust the barrel exactly the same on every one to benefit from all the screwdriver slots lining up. I honestly dont think you could adjust them all the same and obtain a perfectly smooth surface on the head and washer.
