The metric NDM (economy t nut) weld nut is a dual-tab spot weld nut designed for
applications requiring additional strength where tension is against the weld. Established
as the standard slot fastener in the aluminum extrusion industry (economy t nut).
The location of the twin-tabs enables the NDM to be used in bridging corners and
recessed areas. A precision pilot speeds location and provides a full thread engagement.
The NDM can use the same electrodes, equipment and settings used in production,
thus eliminating setup and changeover time, thereby lowering in-place-fastener cost.
