Info
Self-Clinching Plunger Assemblies provide a captivated spring loaded positioning pin for use in thin sheet metal components such as draw slides and consoles. When fully retracted the plunger pin sits below the underside of the panel and features a twist to lockout design (type NTL2), so the plunger pin can be locked in a fully retracted position. It can also be supplied without the lockout feature (type NSL2). 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 Plunger Assemblies are manufactured from electro nickel plated carbon steel and are suitable for installation in ductile panels with a recommended maximum hardness of 80 HRB.
