??? There is: 510 threads to 901 threads, 901 threads to 801 threads, 901 threads to 4081 threads, etc., unless you mean something else.
This is more of what I was referring to, but is is still a little dated.
The Basic Six
The six most common connection thread types are 401, 510, 801 (Penstyle), 901, 4081, and E9. So, what is the difference between these? There are three characteristics that determine each of these types: Barrel size (diameter of the threads), thread pitch (the spacing of the threads), and gender of the battery connection (male if the battery screws into the atomizer and female if the atomizer screws into the battery). Here is a table showing these characteristics of the six thread specs.
Thread Spec, Barrel Size, Thread Pitch, Battery Gender, Other Names by Which The Standard Is Called
401, 7 mm, .5 mm, male, 402, 403
510, 7 mm, .5 mm, female, KR808-A, KR808-B, L88B
801, 9 mm, .75 mm, male, Penstyle, BE112, DSE801, E11, Joye302, Joye304, KR108, M201, RN112
901, 8 mm, .75 mm, male, DSE901, DSE508, DSE568, KR808-D, KR808-D1, RN4075
4081, 8 mm, .75 mm, female, DSE103, RN4081
E9, 7.5 mm, .75 mm, male, KR808-D2, V0
Product Compatibility
Anyone who has done much perusing of our sales web site (nwvapors.com) will notice that all of our products are designed around either of two standards. Our 510, EGO, and KGO products and most of our accessories are based on the 510 thread spec. Our Echo products, the brand-new Scoo e-cigarette, and the 808D-1 Cartomizers are based on the 901 thread spec.
Now, even with all this information, you may still not know what to buy because you dont know what thread spec the e-cig in your hand conforms to. So, to help you out, here is a list (admittedly incomplete) of e-cigarette products and the thread spec they conform to. Please note: we have not tested the compatibility of all these products. This information is provided based on empirical data and may not be completely accurate.

Final Disclaimer
Batteries and atomizers/cartomizers have different methods of providing for air flow through the e-cigarette. They all have slots and holes of various forms and in different places. Even though products are manufactured to the same thread specification, it is possible that they wont work (or will work poorly) when used together because of inefficient air flow.
Got this on Northwest Vapors website,
E-Cigarette Standards | , cant get the table to come up right, but it is at the link above. I even placed an order with them before I could get off the site.
