CTHULHU Fast Nut Knurled 510 Adapter
The Cthulhu Fast Nut Knurled 510 Adapter is a quick and easy solution to the standard flush nut. The Fast Nut has a knurled ring that sits above the mod, allowing for a tool-less removal and installation. The Fast Nut can accept most standard 510 drip tips, and comes with a white delrin nipple tip. This product is designed with the standard 'Billet Box' thread pattern and is compatible with Boro Box Mods with the same thread pitch.
