Stupid question that I know this group can answer in about 6 seconds

I have a Stihl 009L chainsaw. Kid you not, I haven’t used it since 1996 or 97.

Clean the carb and fresh gas. Fired right up.

The question: the handle is detached on the left side. The bolt went MIA

What size and pitch is it?

Scroll through the parts list to find your specific bolt.
