“The internal frame was designed, fabricated
and installed around a tubular steel skeleton.
A tubular steel secondary frame carried the
many brackets to which the stainless steel
‘skin’ was attached using C50L fasteners,”
explainedJohnRickers, systems development
manager at Alcoa Fastening Systems.
“The C50L’s powerful clamp strength
combined with Huck’s hydraulic tooling
enabled the sheet to be immediately
shaped into place during installation, thus
eliminating the additional time it would
have taken using a conventional nut and
bolt system. Not only did the solution meet
the mechanical requirements of holding
everything in place, but the fasteners were
quick and easy to install.”
David Tyas, managing director at Permalok
Fastening Systems, added: “The C50L
lockbolt is historically a heavy industry
fastener, and this application showcases
the enormous strength of the product – as
shown in its ability to bend the sheets to the
supporting frame – and the ease with which
it can be installed. It is also interesting to see
how the fastener has been incorporated
into the aesthetics of the sculptures.”

Cable labels take the heat
UK labelling manufacturer Silver Fox has
reported positive results from recent
high temperature tests on its printed
labels. The tests, carried out by the UKAS
certified Environmental Test Services over
a three-month period, were performed
in accordance with the test specification
MIL-STD-202G, method 108A.
The resulting certificate relates to the white,
yellow, blue and red Fox-Flo UV-stable LSZH
tie-on cable label.
When tested, Silver Fox’s Fox-Flo labels
showed no change after being subjected
to a temperature of 70ºC for 500 hours.
The labels continued to perform well when
subjected to a temperature of 85ºC and at
100ºC for 500 hours, with only the white label
becoming “a shade darker” according
to testers, with the same observation after
exposure to 100ºC for 1,000 hours.
Nick Michaelson, CEO of Silver Fox, said:
“These labels are used in the energy,
power, rail and data and telecoms
industries worldwide, often in demanding
conditions where they can experience high
temperatures, so it’s important that the labels
are tested thoroughly to ensure that they’ll
perform well under ‘real world’ conditions.”
Offshore fasteners
Measurement technology is being adopted
across a number of major offshore oil and
gas projects in an effort to extend the life of
essential platforms. Work is underway on the
re-fit of measurement fasteners on existing
