Remnant 2 axle size

I need to replace an axle for the Remnant 2. Would someone be so kind as to link me to a correctly sized axle?

Why don’t you take it to the hardware store and see what fits.

Do what JBH said then if that store doesn’t have one get a 4mm x 12mm set screw. Ace hardware is your friend.

Alright, thanks! I appreciate the help, I’ve never had to replace an axle before.
