The RD weld nut was designed for applications where orientation is a factor, where there are space limitations and where they will be applied by automatic equipment. The RD weld nut is a self-locating, through-hole weld nut with three precision, spherical weld projections that give strong, uniform welds. RD projection weld nuts offer clean design and reliability. They can speed up production and reduce fastening costs 

The BFWN and BFWNS series part is ideally suited for use in confined areas because of its small diameter relative to the thread size. The precision pilot orients the nut in the mounting hole eliminating the need for fixturing or special electrodes.
