Info
Self-Clinching Low-Profile Panel Fasteners provide a captivated spring loaded screw for use in thin sheet metal where panel to panel attachment is needed and subsequent access is required. They reduce loose components and so reduce the risk of loose hardware being lost or falling out and damaging internal components. Featuring a  recessed head which sits over the body when in use, giving a lower profile. Actuation can be by tool or hand. Utilising a special proven clinch feature, this fastener has excellent pull-out and push-out characteristics whilst providing a flush finish on the underside of the panel. Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of the panel.   Self-Clinching Low-Profile Panel Panel Fasteners are available in a range of thread sizes, manufactured from electro nickel plated carbon steel and are suitable for installation in ductile panels with a recommended maximum hardness of 60 HRB.
