Torque alone to secure brake?

I'm building up a 330 Dakota (.338 cal with about 10% more case capacity than a 338WinMag). With 75+ grains of Retumbo under a 300gr bullet, I know that this will be a fairly heavy recoiler. My current plan is to put a Holland Quick Dump brake on it. Cutting the threads and indexing the brake to the barrel is pretty straightforward, but my question to those with experience in these things is: What keeps the brake from spinning off of the barrel? I am not looking at my components right now, but I think that the RH twist of the barrel will twist the gasses so that they will apply a torque on the brake in the direction of removing it ... do you guys just torque these brakes on really tightly so that they don't come off? The brakes are too expensive to launch downrange every 10 rounds

Thanks in advance!

I would put a small bit of Loctite on it. You can remove it if you need to but it will help preventing the initial movement that results in part loosening.
