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