Hammerhead bolts attach pipe clamps
HKS hammerhead bolts, which Stauff
will be introducing for the first time at
this year’s Hanover trade fair, round out
the company’s product range in the area
of clamping equipment for pipes, tubes,
hoses, cables and other components in
accordance with DIN 3015.
The new hammerhead bolts facilitate
easy and safe installation of Standard
series and Twin series Stauff clamps
in usual cable trays with diagonal,
lengthwise or crosswise slots and
perforations. This refers to containment
systems made of bevelled steel or
stainless steel, which are generally used
for attaching electric lines, and even
sometimes tubes and hoses, to ceilings
and walls.
This solution is often used for handling
large numbers of cables, such as those
found in large buildings, but is also used
in key industries such as marine, oil and
gas, or process technology.
The slotted or perforated ducts give
maximum flexibility for installation
and inspection as well as future line
replacements.
Users have already had the option
of attachment with Stauff clamps in
numerous varieties of containment and
support systems. Conventional hexagon
head bolts or socket cap screws were
inserted from above through both the
clamp halves and cable trays, and the
hex nuts were tightened from below,
which required the use of a second
spanner.
HKS hammerhead bolts reduce the time
needed for installation and do not require
a second tool. They are attached from
the upper side with hex nuts and fit
securely into the slots and perforations
in the substructure when turned 90°. The
range of HKS hammerhead screws will
be available in sizes M6 and M8 at the
time of the market launch, and have been
designed for attaching Standard and
Twin clamps up to size 3 in accordance
with DIN 3015. These are suitable outer
diameters between 6.4 and 25.4mm.
In order to ensure optimal corrosion
protection even in extreme conditions,
such as for the offshore industry or
process industry, the screws are made
of V4A stainless steel. This complements
the recently introduced ACT clamps,
which prevent crevice corrosion to
pipelines thanks to their design.
Walter Stauffenberg GmbH was founded
in the 1950s, and was initially a contract
turning shop. Today the company
operates under the trade name Stauff,
developing, producing and marketing
fluid technology components for use
in plant construction and mechanical
engineering.
