I have seen a lot of searches for e-Cig thread sizes so that tells me that there are a lot of people out there who are looking to create atomizer connectors or other types of e-cig connections. Below, I will list the thread sizes of the most common e-cigs out there.
To make your own atomizer connectors for e-cig battery mods, you may need to make your own. The list below lists the different tap and die sets you may need to use to cut threads for the e-cig atomizer you are trying to mod for.
A Radio Shack “M” type power jack (RS# 274-1582) has the exact thread sizes for a 901 atomizer and works perfectly for a 901 atomizer connector (which is what I use in my “Puck” mod).
For a 510 atomizer though, there is nothing you can use as a jack for the atomizer to screw into that already exists so you either need to make your own, use one off an old 510 e-cig battery or order one.
Thread sizes for the most common e-cig atomizer/batteries.
- 901 8mm X .75
- 801 9mm X .75
- 510 7mm X .5
- RN4081 8mm X .75
- EGO 12mm x .5
A 901 Atomizer has female connector, Battery has male connector.
A 801 Atomizer has female connector, Battery has male connector.
A 510 Atomizer has male connector, Battery has female connector.
A RN4081 has female connector, Battery has male connector.
An ego connector has the larger outer set of threads for ego style tanks and most ego mods also have screw threads for a 510 in the center.
There are various places to get taps and dies to cut the threads you need.
Here are some links to get the exact taps and dies for whatever e-cig model you are designing for. To make threads for a…

These are the most common e-cigarette sizes. There are others but these are the most popular e-cig configurations.
