Nyloc Self Clinching Nuts provide a strong reusable female thread in panels that are too thin to be conventionally tapped. A nylon element provides a reusable non-metalic prevailing torque locking feature suitable for use in temperatures up to 120°C.
Utilising a special proven clinch formation, along with a radially knurled collar, this fastener has excellent torque out and push out characteristics whilst installing flush on the underside of the panel.
Available in Steel and Stainless Steel in thread sizes M3 - M5.
Like all self clinching fasteners they are installed using a parallel squeezing action so require access to both sides of the panel.

Note: This part may be used in panels from 1.0mm to 1.49mm if the fastener is not installed with the knurling collar fully flush. The knurled collar must be left proud of the panel as if the sheet thickness was 1.5mm or less. Incorrect installation of this fastener may result in the collar fracturing in panels thicker than 1.7mm where the mating screw is tightened past the maximum recommended torque.

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 knurled collar is installed flush with the top of the panel or until the shank is flush to the bottom of the panel for panels thinner than 1.5mm. Do not over squeeze the fastener into the panel as this will result in the threads being crushed or the collar breaking.
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.
