The self-clinching hex nut type Kalei is a pressure fastener fixing system used to obtain extremely solid threads on thin sheets. The hexagonal shape of the Kalei nut makes it possible to obtain high resistance to torsion and extraction.
It can be supplied in galvanized or stainless steel for different sheet thicknesses.
The Kalei nut is easy to assemble using the special pneumatic press or with the hydraulic press, visible in the fixing systems product menu.
