Good responses. One more that might cause it. Bolt circles are off. Either on the wheel or the hub. If the bolt circle is off for example on the wheel (not likely but possible) or the hub then you will be pulling the stud over when torquing and with the way studs are fully threaded they cant take a shear load.
Just a thought and maybe something to look at. Easy to measure the bolt circles and see if any are off. And because its the same wheel I would check the hub first. Kinda suspicious that they are all on one wheel. Kinda points to a mismatch on that hub, not the batch of wheels or the studs. JR
