No clue the thread pitch for the tripod...it mounts to standard tripod thread pitches tho. I've tried on 2 different ones and they both work (both are mini-tripods tho).
BTW, I received new 1mm x 10mm o-rings from Waion and they work great. No binding at all now, even when twisting fast. And I got them extremely fast...Waion's customer service is amazing. I'm liking the LR5-3W more and more.
