Captive Fastener Brand of Self Clinching Panel fasteners Series CPFK provide a solution where design engineers want a spring loaded panel fastener assembly to be used in PC Boards so that they are easily assembled, and removable in the assembly. The panel fasteners are available in 300 series stainless steel and are passivated to ASTM A967.  The Broaching type of panel fasteners offer a low cost of installation and provide a strong reusable thread in PC Boards as thin as .060” / 1.53 mm thick.  For the self clinching spring loaded panel fasteners to be installed properly, the fasteners must be sufficiently harder than the panels into which they will be installed. The stainless steel plungers can be installed into PC Boards with a maximum hardness of HRB 70.

The self broaching panel fasteners are to be installed into brittle material which allows the fastener to broach into the board when installed and provide a permanent reusable thread in the PC Board assembly. Since the panel fasteners are captivated in the assembly there is no worry of losing the screws during servicing in the field. Each self broaching panel fastener is installed into the proper size hole in the mating PC Board and are then broached into place using a squeezing force. The recommended hole sizes and suggested installation force is available in our catalog.  The CPFK Series of panel fasteners eliminate the possibility of loose hardware in the assembly which is a very important feature for design engineers particularly in electronic enclosures and cabinetry. When properly installed the self broaching panel fasteners provide excellent push out values that meet or exceed the industry standards. The performance values are readily available on the product pages on our website. The panel fastener’s design allows the fastener to retain its dimensional integrity during the broaching process. The CPFK broaching fasteners, unlike a swage fastener or rivet, do not deform around the substrate but are broached into the hole provided in the PC Board assembly.
 
The self broaching CPFK self clinching fasteners are available in inch and metric thread and are REACH and RoHS compliant. If 2D or 3D prints are required they can be downloaded from our website.
