Primary
Uses
&
Applications
-
Medical
Devices:
Assembly
of
surgical
instruments,
diagnostic
equipment,
and
implantable
device
packaging
where
cleanliness
and
corrosion
resistance
are
paramount.
-
Marine
Electronics:
Navigation
systems,
underwater
sensors,
and
communication
devices
on
boats
and
offshore
platforms.
-
Laboratory
&
Analytical
Equipment:
Spacing
components
in
equipment
exposed
to
chemicals
and
requiring
easy
decontamination.
-
Food
&
Beverage
Processing:
Equipment
assembly
where
cleanability
and
resistance
to
corrosive
cleaning
agents
are
required.
-
Chemical
Processing:
Mounting
components
in
or
near
equipment
exposed
to
corrosive
vapors
or
splash.
How
to
Use
-
Clean
Environment:
For
medical
and
high-purity
applications,
install
in
a
controlled,
clean
environment.
-
Installation:
Use
a
clean,
3/16
inch
hex
wrench.
Carefully
screw
the
male
thread
into
the
receiving
tapped
hole.
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:
Use
a
matching
M3
stainless
steel
screw
(max
length
~4mm)
to
secure
the
component
to
the
female
thread
of
the
standoff.
Ensure
the
screw
length
is
chosen
to
fully
engage
the
female
threads
without
bottoming
out.
-
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.
