Self-clinching fasteners

In modern sheet metal fabrication, creating reliable fixing points without additional welding or complex machining operations is an important requirement for many industrial applications. Self-clinching fasteners provide an effective solution by becoming permanently integrated into thin metal sheets through a controlled pressing process, creating strong and accurate fastening points for subsequent assembly operations.

Press-in fasteners for sheet metal are installed into a correctly prepared hole by applying a controlled installation force. During the pressing operation, the surrounding sheet material flows into the locking area of the fastener, creating a secure mechanical connection with high resistance to rotation and push-out forces. This technology allows manufacturers to obtain reliable fixing points even on thin panels while maintaining a clean external surface.

A.T.S. Lamberti supplies a complete range of self-clinching fastening solutions and supports customers in selecting the most suitable component according to sheet thickness, material type, mechanical requirements and assembly conditions. The range includes self-clinching nuts, self-clinching studs, spacers, standoffs, captive screws, self-clinching pins and PCB spacers for different industrial applications.

Self-clinching fasteners are widely used in sectors including sheet metal manufacturing, electrical enclosures, electronics, automation, automotive components and industrial machinery. They are particularly suitable for panels, covers, housings and metal structures where a permanent fixing point is required while maintaining high assembly accuracy and repeatable production results.

A.T.S. can supply self-clinching fasteners in zinc-plated steel, stainless steel 303 and stainless steel 400, allowing the correct solution to be selected according to application requirements such as mechanical strength, corrosion resistance and operating environment. Selecting the appropriate material and configuration helps ensure reliable performance throughout the service life of the assembly.

For the correct installation of self-clinching components, A.T.S. also provides hydraulic and pneumatic presses for press-in fasteners. These systems allow controlled and progressive application of the required force, helping manufacturers achieve consistent installation quality, reduce assembly errors and maintain reliable production standards.

With experience in industrial fastening systems, A.T.S. Lamberti supports engineers, manufacturers and technical departments in identifying the most suitable self-clinching fastening solution for each application. Through technical advice and application support, A.T.S. helps customers improve the reliability and efficiency of their assembly processes.
