Super Strong Magnetic Ball Bearings - Bulk Buy?

Hey, I got some magnetic ball bearings and put em in my 5mm bolts.

Now I can't get em out, so I bought a very strong magnet - 16kg pull, and they still won't fucking budge. Only been in a few days and haven't gotten wet, sprayed with WD40, made no difference.

Any ideas?

I was thinking that the BBs would magnetize the bolts, making a magnet on the end of it useless :/

Just seen this...

Dear oh dear.

So, alloy bolt heads with magnetic BBs would work, if you greased them in. Magnet to remove.

Or use glue on normal ones...

What I want to know is, how does Murts change a tyre?
