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 anvil with the shank facing up like in the diagram above. Locate the panel mounting hole over the shank of the fastener. Ensuring the panel is held level, apply a parallel squeezing force until the shoulder of the fastener is seated against the panel and the spigot is flared. Do not over squeeze the fastener into the panel as this will result in panel deformation or damage. When installing flare-mounted broaching standoffs, please pay attention to the minimum hole centreline to edge limitations. Flaring Punch detail is per end user requirement to achieve desired spigot profile

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.

Info

Flare-mounted broaching standoffs provide strong reusable threads in a spacer format in non-ductile materials such as printed circuit board, polycarbonate, acrylic, glass epoxy and resin laminate components. Featuring an axially knurled shank combined with a spigot that is flared out during installation, the serrations are designed to cut into the panel material as it is installed, resulting in an interference fit that offers good torque-to- turn resistance while the flared spigot provides increased pull-out performance. Installation is simple, prepare the specified hole and using a flaring punch and appropriate anvil, apply a parallel squeezing force to press the part into the hole. When installing in printed circuit board, flare-mounted broaching standoffs are suitable for use in non-plated holes only. Available from stock in metric thread sizes in electro tin plated brass.
