Interesting. I’ve had at least 25 pairs. Never an issue. But I do lap them, and use a torque wrench.
I've had a bunch of them, only the 2 cracked. I don't lap and only use 2 fingers on the short end of the wrench to tighten alternating screws so there is a chance I over-tightened...but nothing else has ever failed and the same technique is used. That rifle lived (still lives) a hard life as it lives in an ATV boot and is used/carried/driven every day. The DNZ mounts which replaced the LW's are still good.
