It some how seemed wrong so I took the time to read our FORUM topics to find out they should not be removed. Question...how do I put the round head bolt back or can I use a grade 8 or 9 bolt in it place. | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | I would grind six sides to the round head to except a socket.
It is important to use that shouldered bolt.
I would also use Loctite on it.

Glad it worked out for you!
