Yes that could be a problem, but I have eight Invader Mini mods. I always like screwing on the top cap to the atty first (I think this is easier on those chrome plated brass threads). And when you screw both on the mod and it stops. I only tighten a tad more by the top cap only. And I have always been able to get everything loose once again and you get a really solid 510 connection.But heatvape hybrid connector cap do give me problems at times when my tank got screwed in too tight, it is very difficult to remove and twice I unscrewed the deck instead...you know how the rest of the story goes.
