When working with stranded wire it is good to pay a little more and get
better fixtures that use a screw tightened clamp to hold the wire, than
trying to wrap the wire around a screw.


If you can't wrap the wire around a screw so that
it is in full contact with all of the strands,
then you should practice a little more or not do
the work. A few stray strands separating at the
cut end are not than uncommon and make no
difference if the screw fully contacts the wire
near the insulated end.
