Metric thread wood screws, creative exhaust fix

[tri again]

So this is what I found holding the exhaust to the head of
a new '84 - 125m.
One looks like a mini lag screw and the shiney one has a 7/16" head.

Must of used a fancy tap for that lag bolt:lol: Maybe he was building a deck and got side-tracked:wondering
