A thread is carried on the shank of the fastener having an included thread angle less than the standard included thread angle, a major diameter greater than is standard for the particular fastener size, and a root width less than is standard. At least one locking lobe is formed on the thread which lobe is engaged by material displaced by the thread whereby to effect locking.
