lead/probe that can grab a small bolt?

Question

Hi, I'm wondering if I can get some leads/probes that can grab onto some terminal block bolts that are around 5mm wide. I want to be able to test the voltages on the bolts without having to screw anything on, or hold leads in place. My alligator clips almost work, but slide or fall off too easily.

I am wanting something that had a four-claw grabber on the end of it, like you see on those pick-up tools for grabbing dropped screws or whatnot. But I haven't been able to find anything like that on the Internet yet.

I'm familiar with the mini-grabber leads that are easy to get on Amazon, and also similar ones with the u-shaped hooks, but these would be too small to work on these posts.

Could anybody point me to a product like this, or some similar idea that might work?
