Check out these Sweet 510 base connectors

[Kgb424]

I found these at FatDaddy Vapes, they are 22 mm sealed 510 connectors with a spring loaded center pin and you can use or not use the trim ring, I like the look of the base with the trim ring, I bought these for my DNA30 mods I'm going to build two DNA30 mods and the other ones in the pic, the first ones you drill a hole and press fit, not good it turns, then the second ones has too small of a lock nut, and it pulls out, So it took me awhile and some home work and scored these sweet 510 connectors. That have a nice lock ring and nice ground connection ring for good contact so it fires every time you push the button.

I'm going to use the other 510 connectors, the ones with the lock ring and make some rda work stands, cause my ohm meter with the 510 connector broke, it twisted the wires, and broke loose from the plastic when I tried to unscrew a stuck on RDA, so that's why I bought the sweet 510 connectors, so it doesn't happen when I build my mods, just need to find some sort of stand/ case to mount the cheaper 510 connectors into and make stands.

there back in stock , bought some on June 21st to make my work stand.
