Where else is a 7mm - .5 thread used besides these 510 atty's/batteries???

[Chip_]

Anyone know where or what in the world these darn thread sizes are used on? I am talking about the 7mm x .5 threads.

I have SAE/METRIC tap and die sets. But it only came with 7mm x 1.0, and 7mm x .75!!!

Everywheer I go, I cannot find 7mm x .5 --- anywhere. So the question is what in the world is this type of thread used on??? It has to be used on something other than just these E-CIGS, other wise this size wouldn't be on the charts...

Anyone know??

In almost 2 years of vaping I have yet to come across anything that a 510 will screw into.

I'm sure you could find a tap and die set online somewhere, probably china, but with atty and battery connectors costing as little as 99 cents, is it worth it?
