Designed
for
demanding
industrial
applications,
our
Heavy-Duty
Hex
Standoffs
provide
robust
spacing
and
mounting
solutions
where
strength
and
reliability
are
paramount.
The
H4.75-M3x31+6
size
is
built
to
create
durable,
high-clearance
connections
in
challenging
environments.
Made
from
A4-80
(316)
Stainless
Steel
with
a
protective
blue-white
zinc
plating,
they
offer
superior
resistance
to
corrosion,

and
moisture
compared
to
standard
A2-70
grade,
making
them
suitable
for
industrial
controls,
telecommunications
infrastructure,
and
outdoor
applications.

Primary
Uses
&
Applications
-
Industrial
Automation:
Mounting
PCBs
in
PLC
cabinets,
motor
drives,
and
robotic
systems
where
shock,
vibration,
and
humidity
are
present.
-
Telecommunications
Infrastructure:
Used
in
5G
base
stations,
network
switches,
and
outdoor
cabinets
requiring
mechanical
durability
and
environmental
resistance.
-
Power
Electronics:
Spacing
and
mounting
boards
in
power
supplies,
inverters,
and
battery
management
systems
within
industrial
settings.
-
Outdoor
&
Marine
Equipment:
Providing
corrosion-resistant
mounting
points
in
sensor
housings,
navigation
equipment,
and
control
units
exposed
to
the
elements.
-
Transportation
Electronics:
Securing
control
units
in
automotive,
rail,
and
marine
applications
(non-safety-critical).
How
to
Use
-
Preparation:
Ensure
the
tapped
holes
in
the
base
material
are
clean
and
free
of
debris.
Using
stainless
steel
screws
is
recommended
for
optimal
corrosion
performance
match.
-
Installation:
Use
a
correctly
sized
hex
wrench
or
socket.
Screw
the
male
thread
into
the
base
material.
The
A4-80
stainless
steel
is
stronger
but
can
be
prone
to
galling
(cold-welding);
using
a
moderate
speed
and
avoiding
over-tightening
is
advised.
-
Final
Assembly:
Place
the
component
over
the
standoff
and
secure
it
with
an
appropriate
stainless
steel
machine
screw.
The
deep
female
thread
(25mm)
allows
for
a
strong
connection
with
various
material
thicknesses.
-
Torque
Control:
For
critical
applications,
use
a
torque
wrench
according
to
the
specifications
for
A4-80
stainless
steel
to
ensure
a
secure
connection
without
damaging
the
threads.
-
