I can't see any difference between ones bought from Halfords or
from TLC. Neither does RS etc list ones for low voltage stranded
and mains solid core - and they of course would cover both events
with their products.

I would be cautious about crimps, unless the blurb
actually said the word 'solid'.

For example, I assume that all RS crimps are for
stranded wire, with the only exception being the
range from Solistrand, whose blurb actually does
say "designed for solid, stranded, and irregular
shaped copper conductors".

The Solistrands are uninsualated crimps, of a thicker
gauge copper than usual, with heavy serrations down
the bore, presumably to bite into solid copper wires.
