Recoil starter bolt diameter and pitch – 02 TB

Looking for the diameter, length and pitch of the inner recoil bolts, part #3081665. It’s listed as (10) on parts diagrams, but I’m unsure if that’s head size or actual bolt diameter, either way I’d still like some confirmation if anyone has one on hand they could put to a bolt gauge that’d be great!

Piecing together my $300 TB project and these bolts weren’t included in the purchase.

Thanks guys.
