摘要

A joint for securing a tubular member to a support member comprises a pair of extruded holes in the sidewall of the tubular member opposite each other, a hole in the support member, the tubular member being disposed against the support member with the extruded holes in alignment with the hole in the support member, and a self-tapping fastener engaging the support member and passing through the hole therein to threadedly engage both extruded holes, the threaded fastener having cut complementary threads in both extruded holes during fastening.
