NP - Self Clinching Fasteners - Keyhole Standoffs
|
|
Self Clinching Keyhole Standoffs reduce both the time and costs associated with traditional assembly methods for, say, PCBs.
The design of this fastener allows a panel or PCB to be quickly slid sideways and locked into place via a keyhole shaped hole in the mating panel. To remove, simply slide the opposite way and lift the panel off. A Through-Hole or Blind-Standoff can also be used in conjunction with this part to provide a secure fixing with 1 screw removal.
The use of this fastener will also minimise the amount of loose hardware (screws, for example) usually associated with such tasks.
Installed from the bottom of the panel, Keyhole Standoffs install flush and are suitable for installation in Steel and Aluminium bottom panels of minimum 1 mm thick with the Keyhole feature suitable for top panels of 1.45 mm to 1.62 mm.
Available in Steel, Stainless Steel and Aluminium in a range of lengths to suit your application.
Like all self clinching fasteners they are installed using a parallel squeezing action so require access to both sides of the panel.
Please check for availability before specifying.

Installation Guide
|
|
 |
|
First punch or drill the correct size hole. DO NOT deburr the hole prior to installation as this will remove material required during the clinching process. It is preferable to install the fastener from the side of the panel with the burring or blow through.
Place the fastener in the hole like in the diagram above making sure the part is seated squarely.
Apply a parallel squeezing force until the head is installed flush in the panel.
When installing Self Clinching fasteners, please pay attention to the minimum hole centerline to edge and parent material hardness limitations.
For special applications or if you are unsure of any aspect about the usage or installation of this fastener, give our sales office a call and we will do our best to offer you a solution or give advice on your application.

The above data is based on average values obtained in a test environment. Variations in hole size, panel material and installation will effect performance. It is recommended that you carry out your own performance tests in the actual application. Contact our sales department who will be happy to supply samples free of charge.
