Product:Chymney (lug) nut

The Chimney nut is a fastener composed of two flaps in clip form.
The design of this nut means that a double elastic force is exerted when tightened. The upper flap has a longitudinal slit on either side forming struts which increase the grip of the nut onto the panel.
In the middle of the upper flap there is a hollow cylinder or “chimney” with multiple threads which when given the correct torque guarantees maximum fastening and assembly strength.
No special tools are required to mount chimney nuts, and they can be assembled much more quickly and easily than conventional nuts and costly operations such as tapping, welding or riveting can be avoided. They are normally mounted on the edge of a panel but can also be used in a rectangular mounting hole in the middle of a panel. The
use of this nut allows slight adjustment within the mounting hole thereby ensuring correct alignment of the panels.
