Aluminium fasteners
facilitate lightweight
construction
Aluminium screws from Arnold
Umformtechnik are finding uses
in the joining of magnesium
components in transmissions,
housings as well as load-bearing
and stiffening applications.
Alufast fasteners are especially
useful with material pairs
exposed to thermal stress as they
significantly enhance the security
of threaded fastener joints.
Aluminium screws weigh only
one-third as much as equivalent
steel screws so with large volumes,
the weight savings can significant.
The type 6056 aluminium
Spelsberg ELS, which claims to
be Europe’s leading manufacturer
of non-metallic electrical
enclosures, has released a shortform
catalogue for 2012/2013
that features an overview of some
of its market leading new enclosures
and accessories for general
electrical applications. The
catalogue also focuses on some
of Spelsberg’s most popular
enclosure ranges and cable entry
accessories while providing key
technical information to help
simplify the specification
process.
56
alloy used for Alufast
fasteners has a proven
track record of durability
for joining magnesium
components
with threaded fasteners.
The material has
good characteristics
for thermal expansion,
corrosion resistance
and recycling.
At the same time,
Alufast products fulfil
stringent requirements
for retention of
clamping force, thermal
stability and
weight reduction, the
maker claims.
Alufast fasteners also exhibit
good corrosion characteristics in
contact with magnesium. The relatively
small difference in electromotive
force significantly
reduces the risk of corrosion
compared with steel fasteners.
The mechanical properties of the
screws are practically stable
under long-term stress at temperatures
up to approximately 150
°C and brief temperature excursions
up to approximately 180 °C
do not pose a risk.

Hardware catalogue covers
enclosures and accessories
Also included in the catalogue
are some of Spelsberg’s innovative
enclosure accessories including
the IP67 Klikseal insert -
which allows installers to make a
compact, watertight cable entry
in a matter of seconds - and DIN
Rail mounted terminal products.
The catalogue’s concluding
pages feature technical information
to allow users to compare the
featured products’ performance
capabilities and simplify the
specification process.

Mechanical struts
suit heavy weight category
Associated Spring has launched
of a range of mStruts to complete
its current offering, which now
includes everything from high
quality gas struts to fully stainless
models. Particular success
has been seen with manhole covers,
inspection covers/panels and
refrigerated vehicle applications
where low maintenance, repeatable
loads and temperature are a
particular concern.
Recently the company has
been working closely with automotive,
foundry and commercial
vehicle businesses on numerous
engineering projects. From production
line health and safety
solutions to bespoke systems, the
company’s engineering team is
constantly pushing the range to
be more versatile and fit with the
customer’s needs, it is claimed.
With their proven long life,
the mStruts are showing that they
are a long term cost saver for
their customers when compared
with gas struts in similar applications.
With over 70,000 stock
items and new ranges of 316 type
and stainless steel springs,
Associated Spring says it is confident
of meeting all customers’
Stop locks
keep things in place
The GN702 four position indexing
stop lock from Elesa is
designed for the location and
retention of drawers, access
doors and panels and offer a low
cost and simple solution for the
engineering designer. Stop locks
having a standard red latch with
black mounting flange are used
extensively on aircraft, fire
engines, ambulances and similar
service vehicles where rapid
manual operation is needed with
robust performance.
The GN702 features a flange
for surface mounting or mounting
with M8 female thread or
with standard rounded square
hole for lock style fitment. Latch
material is zinc die with red plas-
needs, no matter how big or
small.
