When collecting from Fyshwick, it was lucky that I looked in the box when it was given to me as the nuts which were supposed to come with the bolts were missing. I would have been very unhappy if I had driven home to Nicholls only to find my order was incomplete.

The bolts had very uneven galvanizing and some were difficult to put nuts on, others impossible.
