Thread: Torx head pivot pin

I have a Chandler custom with some sort of Torx-head pivot pin. Problem is that this fitment is smaller than any Torx drive I have or have seen (T-5 I believe is the smallest I have). So, does anyone know the size and where I can get a socket to fit? Thanks.

I use one of these which covers most the torx screws I have seen or had to work on. I also have several single ones. But the Husky range has been my workhorse. I bet it's a T4 you need. That is very small. I also have the same range set from Kobalt which I believe came from Lowe's.
