What fasteners can be used in a hydroformed tube?
A- Most any fastener currently used in stamped and welded assemblies can be used in a hydroformed tube. The most cost effective fastening solution is a self tapping screw threaded into a conical extrusion that is pierced in the tube during the hydroform process. Other more costly threaded fastener options include but are not limited to weld nuts, pierce nuts, riv nuts, and snap nuts. Hydroformed tube can also provide holes compatible with pop rivets, christmas tree style clips, nut plates, and a wide variety of push pins.
