It is fast. It can be applied mechanically just in seconds. Once the fastener is mounted, the connection can operate for years. Excessive torque resistance: The weldless clinching fastener mounts the assembly parts with a very economic and fast way without deteriorating micro crystal structure. It provides a very strong connection. NORM weldless clinching fasteners are developed to provide a very strong torque resistance with high axial clamping loads without performing any welding operation. It mechanically creates a permanent joining without causing any metallurgical change in assembled parts.
