This is 3.5mm ball links and it works with WLtoys too. I use it to mod my car. Whole length is 11mm and the screw length is 6mm. Unfortunately the quality is mixed. Among 3 sets that I bought 1 of them doesn't have screw thread. Buy a lot because you don't know what you're gonna get.

Purchased it second time. Ball head is 3,5mm that is suitable for Wltoys 1/28, such as k989, k969 etc.
