Like, so what if the screws get rusty....the whole snowblower is rusty....so will give plain old pan head sheet metal screws a shot at about $2.99/box 100. It's like the fine balance between improving traction and not scratching up the cement and pressure treated lumber with chains or hex head sm screws.
After seeing what hex heads do, I guess one could turn a dirt motorcycle into an ice motorcycle with about 100 screws or 50/tire. Have never seen a motorcycle out on the Winnipesaukee snow splattered lake ice but it's probably doable. Probably happens in Minnesota or Maine or somewhere?
