ABSTRACT:
A fastener device has a body member for welding and securing structural members together. The body member has a lateral bore extending between an upper flat side and a lower flat side. The sides each have a pattern of externally facing grooves communicating with the lateral bore and an exothermic material fills the patterns of grooves, the lateral bore and a radially extending bore communicating with the lateral bore. A fuse in the radial bore produces intense heat in the exothermic material to initiate an exothermic reaction to melt at least some of the body member, exothermic material, and structural members and weld the body member and structural members together. The man-portable, self-contained, reliable, fastener device permits a relatively unskilled workman to securely interconnect the structural members together at a primitive work site without requiring ancillary equipment.
