How do self-clinching fasteners work?

During insertion, the base material is pressed into a corresponding groove by a knurling or hexagonal platform. Knurling and groove of the fastener are matched to one another in such a way that the deformation is limited to the immediate vicinity of the fastening element.

A completely flush finish is obtained on the one side and high thread stability is achieved by special heat treatment over a compact area.

The self-clinching element displaces the material in the hole, which flows into an undercut in the fastener. After setting, the elements are permanently connected to the base material such that any screw connections can subsequently be removed without risking displacement of the fastener.

Mechanical insertion prevents surface damage, enabling the products to be used even in prefabricated materials.

Typical applications currently include the production of modern communication devices (such as smartphones, computers and laptops) as well as in the automotive industry.

The machines offered by HONSEL simplify and optimise work processes and boost quality and productivity with the reliability and energy efficiency of a hydraulic machine.
