Installation Method & Performance
Performance
√  X
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. 
HRB (ROCKWELL HARDNESS B SCALE) Ensure that you are installing into a panel that is at or below the published maximum recommended hardness for the fastener.
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.
