510 Thread – What is it in Vaping?

Definition

The 510 Thread is the universal screw-on connection system that joins most vape tanks, cartridges, and atomisers to vape mods or batteries. Named after its ten 0.5 mm threads, it has become the industry standard for both nicotine and 0mg nicotine devices, allowing Australian vapers to mix and match components from different brands. Whether you use an Battery“>18650 batterymod or a compact pod-style battery, chances are it sports this familiar female port, making upgrades and replacements straightforward and cost-effective.

Technical Details

Inside every 510 Thread port you’ll find a positive pin surrounded by a negative threadingsleeve. The pin is spring-loaded or floating to guarantee solid electrical contact even when the male threads of an atomiser aren’t perfectly flush. Electrical specs are simple: 3.3–4.2 V from a single lithium-ion cell such as an 18650 battery, 21700 battery, or 26650 battery. While the basic 510 is 7 mm in diameter, manufacturers have created variations—eGo 510 (wider skirt for older clearomisers), 510 with airflow slots, and hybrid 510s that place the positive pin directly on the battery for lower voltage drop in mechanical mods. Always check that the positive pin protrudes at least 0.5 mm to prevent hard shorts.

Usage & Tips

  • Cross-compatibility: Virtually any 510 tank or cartridge will fit a 510 mod, but verify resistance limits and Wattage Range”>wattage range to avoid dry hits.
  • Cleaning:E-liquid or pocket lint can block the threads—use a cotton swab dipped in isopropyl alcohol once a week.
  • Loose connection? Slightly unscrew the atomiser, then retighten until snug; overtightening can strip the threads or push the centre pin too far down.
  • Safety: Never use a hybrid 510 mechanical mod with a tank whose positive pin is flush or spring-retracted; this can create a direct battery short.

History & Context

Introduced by Joyetech in the early 2010s for its eGo series, the 510 Thread quickly eclipsed the larger 808 and 901 connections. Its compact size, reliable conductivity, and open-source design let smaller Aussie vendors craft compatible parts, accelerating Australia’s shift from cig-a-likes to refillable3mg nicotine and nicotine-free devices.
