Rounding of Miyata seat screws

Hello All!

 When I was taking the seat cover off my Miyata seat one of the nuts
refused to loosen - it just spun around together with the srew. This
was because the square part of the srew (which holds the***steady)
had become rounded. I fixed the problem by taking off all the other
front and rear bumper nuts and removing the seat cover as much as
possible. I then held the rounded srew's head steady with vice-grips
and took the nut off.  Feeling proud of myself, I reassembled the seat
only to discover that another***had become rounded and wouldn't do
up tight!
 This means that the bumpers cannot be properly re-installed.
Furthermore it would make any future seat upgrades (change of bumpers
or airseat conversion) very difficult.   Right now the seat is still
in pieces until I decide exactly what to do as any messing around with
it will probably make things worse!

Has anyone met this problem before? Should I just buy new screws?
Would extra washers on each side of the seat plate help? Or would a
steel plate with square holes strategically placed for each nut & bolt
work?  Help!!!

I've had the same problem from time to time. I find that husky lockwashers
usually do the trick.

If it's the bolt that has become rounded off, you can get replacements.
That type of bolt is called a carriage bolt. A well stocked hardware
store might have them. Otherwise you might have to go to a specialized
fastener or***shop. You can buy them, they're just hard to find. If
I remember right, the Miyata seat uses 6mm metric bolts.

If it's the square hole in the plastic seat base that has become rounded
then I would try David's idea an use a lock washer.

 Hmmmm, looks like I've got one of each!  It's off to the hardware store for me.

Thanks for the advice. Hopefully I should be able to fix this problem now.
