Panel Screw Components - Series CFS2, CFR2, CFN2
Captive Fastener Brand of Flush Mounted Panel Screw Components provide a solution where design engineers want a panel screw assembly to be used in panels at least .125” / 3.2 mm thick so that they can be engaged with a slotted screw driver in the assembly. The Captive Fastener flush mounted components consist of a stainless steel screw (CFS2) and retainer (CFR2) and a steel zinc plated receptacle (CFN2). They are often used in access panels for electronic enclosures and in equipment consoles The CFS2 screws are made with 300 series stainless steel, the CFR2 retainer is also made with 300 series stainless steel. The CFN2 receptacle is made with zinc plated steel. The flush mounted panel screw components offer a low cost of installation and provide strong reusable threads in sheets as thin as .125” / 3.2 mm thick. For the self clinching CFN2 receptacle and the CFR2 retainer to be installed properly, the fasteners must be sufficiently harder than the panels into which they will be installed. The fasteners can be installed into steel or aluminum panels with a maximum hardness of HRB 70.
Alternate Attachment Method:
When thin panel material makes it necessary for the screw head to remain above the top panel surface, CFS2 Screws may be used with CFL Flush Nuts as retainers. CFL nuts self-clinch into sheets as thin as .060 in. (1.5 mm) and remain flush on both sides of the panel. CFS2 Screws are rotated through the threads of the CFL Retainers to install and captivate. Refer to CFL section for dimensions and installation data.
Panel Screw Installation
The flush mounted panel screw assembly is to be installed into ductile material which allows for the metal into which the fastener is installed, to flow into the clinch profile of the fastener, and provide a reusable thread in the assembly. Since the CFN2 receptacle and the CPR2 retainer are captivated in the assembly there is no worry of losing the fasteners during servicing in the field. Each self clinching component is installed into the proper size hole in the mating panel and is then pressed into place using a squeezing force. The recommended hole sizes and suggested installation force is available in our catalog at www.captive-fastener.com. The captivated retainer and receptacle 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 clinching panel fasteners provide excellent push out values that meet or exceed the industry standards. The CFS2, CFR2, and CFN2 Series of flush mounted panel components design allow the fastener to retain its dimensional integrity during the clinch process. The clinch fasteners, unlike a swage fastener or rivet, do not deform around the panel but the material in the panel flows around the clinch profile of the fastener.
The Flush Mounted Panel Screw Assembly are available in inch and metric threads and are REACH and RoHS compliant. If 2D or 3D prints are required they can be downloaded from our website.
