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. Thread Size 5/16-18 Width (in) 5/8 Thickness (in) 9/64 Length (in) 1-1/2 Hole In Sheet (in) 0.375 Material C1010 High-Welding Quality, Low Carbon Steel Plain Finish Threads Unified Standard Class 2B ASME B 1.1-2003

I use these and several other sizes to weld into place for various race car fabrication work. They are a super handy and inexpensive means to install fasteners that don’t require extra tools to hold a nut, especially in “blind†applications like behind a firewall or a seat mount. I highly recommend them.
