I'm ordering a Fenix PD20 from Tactical LEDs, and was just curious, does it have square threads? Probably not that big of a deal, but don't they tend to hold up better in the long run?

Answered my own question: did a little further digging & found out that the PD20 has trapezoidal threads. Now my next question: is there any advantage of trapezoidal over square threads? Just curious.
