Fenix thread problems

Well CPF got me into this, so I figured you could help me. I purchased a Fenix L1Tv2.0 just about 2 months ago. I like it very much but have one issue. The threads where the head attaches to the battery tube is constantly gritty. I can turn the head OK with both hands, but it is nearly impossible to turn one handed. I clean the threads often with a paper towel and alcohol and get a greyish grit each time. I have also tried dielectric grease to lube the threads, but there is very little difference.

Does this seem like normal behavior for a L1TV2.0?

I bought it from FenixStore, and will contact them if you (CPF) think it is warranted.

Thanks,

One of my P2D's was like that when I bought it. What I did was lightly lubed the threads, and just twisted the head back and forth over and over to smooth out the threading. I did this for about 20 minutes, taking breaks when I got tired, and it smoothed itself out eventually. I then cleaned the threads and lighty relubed and was good to go. Hope this helps.

I haven't had grit problems, but my grease is constantly turning black on my L2D's- clean off old stuff and re-apply grease, screw up, unscrew, and it's gone black.

Have a look at the threads- you may actually have a bit of grit in there that you can remove with a bit of paper towel/finger.

The problem is probably in the fact that a paper towel with alcohol does not remove all the grit. Some of my Fenixes behaved like yours and only a thorough cleaning with an old toothbrush plus alcohol took away all the grit. Of course this operation was followed by a good lube.

My experience says that eventually the threads get clean and then you have no more problems.

Thanks for the quick responses. I'll try the toothbrush and repeated twisting ideas.

The grit is certainly aluminum shavings. I cleaned the threads today, and could clearly see flakes of metal.
