JL Grab Handle on Glove Box

[Wrangler_Flash]

So on the 2018 JL grab bar, this screw comes out. Does anyone know if there is a Ram mount (or similar) that will fit where this screw is? I've tried taking the screw to my local hardware store to find out the size, but it doesn't appear to be a "standard" size. Anyone know what size screw this is?

Thanks
