It refers to this metric thread sizeThe connector on the mod and atty as well as some drip tips are called 510. Where does 510 come from and what does it refer to? I have been vaping for three years now and I have alsways wondered why it is called 510.
Thank you. That solves that.It refers to this metric thread size

It's an odd ball, rarely used. One particular desinger at one ecig manufacturer specified it before standardization and it became the standard, unfortunately in my opinion.
Same here Robin. It took forever for me to understand what would work with what. I felt like there was a simple answer but didn't ask the question because I felt like folks would consider it a dumb questionWe also have the eGo connection. It was so darned confusing when I first started.
It was either 510 or eGo threads. It took a picture of the difference to get it through mine, and many others, head.
5mm deep, 10mm in diameter ? just a guess

Thank you for reminding me about the kr-808.Thank you beck ... the history of the ecig through the eGo![]()

Looks like there are Chinese chat codes that have been around for quite some time. 510 (wo yi lai) translates to "I'm already here" in English.It's a name, not technical specification. A Translation.
It carried from original device with the threads.
Think 5 1 0 ( a phrase )
I can't remember what it means, something inspiring.
Do a search or tag a native to explain Mandarin character expression and the meaning of numbers.
Am I making sense? Maybe someone can translate me right?
Would love a sturdy "quick release" type of connection...
I agree 100%
Something along the lines of a bayonet style connector could have worked - standardised design and spring loaded on both mod & atomiser, never a gap would be seen
Which incidentally is much like the top cap on the Kraken V2 - which I`ve never seen since and is a wasted design IMO as it`s far better than fine threading with friction, not to mention quicker.
You could be a mind reader!!That's the Dagger. Great little single batt device. TC mode is funny, actually feels like little daggers to the throat because of the pulsing.That mod is beautiful![]()
