Speaker Cable Multiplug Allen screw?


Hi all,
i have the Shunyata Delta Speaker Cable. They are interchangeable spade/banana. It looks like some sort of Allen screw but Allen’s don’t work.
Any Idea of the type and how to change them out? Appreciate any help!

Thanks so much Elizabeth.
Yes it’s a T6 Torx. I’ll pick one up tomorrow and follow your tips. I appreciate your quick response!!
I needed one of those to swap out some WBT bananas to WBT spades and found a Craftsman brand at my nearby Ace Hardware store.
