I politely emailed Youde about the post screw issue. After a few emails back and forth I was told that they are aware and working on the issue. They responded saying they are releasing the newer Goblin tanks with longer screws, as well as replacement screws for those who have the short screws. They said they can mail free screws out if you purchased from Youde, I doubt any of us purchased the Goblin from them directly. They also said that the new screws will be available at B&M stores and online stores and we can contact them for the replacements, I guess this is assuming the stores ordered the screws. Maybe what Youde meant by sending free screws is that they sent them to the stores who have purchased in bulk for resale, maybe. Either way I hope to see replacement screws available soon. I have Goblin 1331 and my post screws are short and pointed. The unstable connection is an issue on the positive block for me, the negative post traps the wire fine. I also noticed that my IGO-s and IGO-f screws fit, but the post block is so small, that those screws heads overlap each other.
I also searched for metric set screws and purchased these in 4mm length.

I will post back after I receive them to let you know if they fit.
