Self Clinching Riveting Screw Head

Self Clinching Riveting Screw Heads are permanent mechanical fasteners designed specifically for thin sheet metal structures. They embed the threaded connection point into a metal substrate through a cold-press riveting method, achieving high-strength internal thread fixation without welding or tapping. Its working principle is based on the radial compression and axial displacement of the sheet metal by the screw head's kerf during the riveting process. This causes the sheet material to plastically flow under the constraint of the mold and fill the gaps between the kerfs, forming a mechanically interlocking structure, thereby establishing reliable resistance to torsion and pull-out forces.

In thin-plate assembly scenarios such as new energy storage systems, photovoltaic inverter cabinets, electric vehicle high-voltage power distribution units, and power electronic equipment, the Self-Clinching Weld Screws for Automotive solves problems such as sheet metal deformation, thread ablation, and subsequent coating damage caused by the heat-affected zone of traditional welding. It also avoids the risk of loosening of the rivet nut under dynamic loads, becoming a standardized solution in the field of thin-plate connections that combines structural reliability and assembly efficiency.
