Installation Method & Performance
Performance
Do not remove any extra material or
chamfer the hole as this could result in
improper installation or reduced
performance.
Ensure that attention is paid to the
minimum hole centreline to edge
dimension for each fastener. Installing
too close to an edge or bend could result
in improper installation or reduced
performance. Minimum centreline to
edge dimensions shown for each
fastener apply to one edge only. If this
distance is applied on multiple sides
there will be significant panel distortion
unless the panel edges are supported
during installation.
First prepare the specified hole in the panel.
Place the fastener in the panel and then locate in the anvil.
Ensuring the panel is held level, apply a parallel squeezing force
until the head of the fastener is seated against the panel. Do
not over squeeze the fastener into the panel as this will result in
panel deformation or damage. Quick-Release Broaching
Standoffs do not install flush (refer to A dimension).
When installing broaching studs, please pay attention to the
minimum hole centreline to edge limitations.
Performance figures are averages obtained over a range of
installations and should be used for guidance only. Panel
material, hole preparation, installation tooling and method
can affect part performance. We always recommend that
you carry out your own tests in the actual application.
Please call our sales team and we will be happy to provide
you with samples as well as offering technical assistance.

Info
Quick-Release Broaching Standoffs reduce the time and costs associated with traditional assembly methods for
panel spaced applications, such as mounting and detaching printed circuit boards, panels, or components easily
without requiring any tools or additional hardware.
This fastener can also reduce or eliminate the risks associated with loose hardware potentially damaging internal
circuitry.
Suitable for installation in non-ductile materials such as printed circuit board, polycarbonate, acrylic, glass epoxy
and resin laminate components as well as ductile panels with a maximum hardness of 60HRB and minimum panel
thickness of 1.27mm. The quick-release end is suitable for any panel material from 1.0mm to 1.8mm thick.
Featuring an axially knurled ring, the serrations are designed to cut into the panel material as it is installed, resulting
in an interference fit that offers good push-out performance.
Installation is simple, prepare the specified hole and using a flat punch and appropriate anvil, apply a parallel
squeezing force to press the part into the hole. When installing in printed circuit board, broaching studs are suitable
for use in non-plated holes only.
Available in various lengths in brass and electro tin plated brass.
