Well the BS1362 fuse certainly isn't the same shape as any screw, since
screws taper to a point, nor is it the shape of any bolt, unless you cut the
head off the bolt.

It's just Jerry's fevered imagination running away with him again.

As for round bar, well it would have to be the same
diameter and length, how many people have bits of round bar just exactly the
right size hanging around the house?

Reminds me of the Americans using penny coins to short out the old
porcelain screw-in fuses when those blew.
