10 Pack 7/16-20 Spot Weld Nuts - Double Tab - ND 3924

This listing is for twenty pieces. The ND weld nut is a dual-tab spot weld nut 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 ND to be used in bridging corners and recessed areas. A precision pilot speeds location and provides a full thread engagement. The ND can use the same electrodes, equipment and settings used in production, thus eliminating setup and changeover time, thereby lowering in-place-fastener cost.
