Gripco offers a series of round projection weld nuts engineered for automation and ease of assembly. Weld schedule and performance are better than a standard hex weld nut due in part to a larger bearing surface. An unthreaded version can be used with thread-forming screws.
Three and six projection types provide a non-rocking, firm current connection during welding. The mass of the projections is increased in proportion to increased pilot heights to assure weld on thick or thin metals.
Gripco's engineering staff can assist you in determining the exact requirements for your fastening needs.
