Self Clinching Fasteners

Self Clinching Fasteners provide strong load bearing male or female threads in thin Steel and Aluminium panels.

Installation is neat and easy, simply locate the fastener into a punched or drilled hole and apply a parallel squeezing force to embed the fastener into the panel.

Self Clinching Fasteners works by utilizing a clinch ring which, when embedded into the panel is filled with metal by a cold flow process, thus effectively locking the fastener into the panel. The very nature of the clinch process gives high torque out and push out performance.

Self Clinching fasteners require a parallel squeezing force to be applied for successful installation. Equally important is the length of time the force is applied. Sufficient time must be allowed for the cold-flow clinching process to work (this is often referred to as the dwell time when installing on a hydraulic press). Self Clinching fasteners cannot be installed with a hammer blow as the force would only be applied for about a 100th of a second which is insufficient for the cold flow process to work.
