A 510 thread is a type of screw thread that is used to connect vape cartridges to batteries. It is a standard thread that is used by most vape manufacturers, so it is easy to find compatible cartridges and batteries.
The 510 thread is named after its dimensions: 5 millimeters in diameter and 10 threads per inch. It has a flat top and a rounded bottom, which helps to ensure a secure connection.
