Abstract
Wrenching lobes of an internally threaded nut are separated by circumferential, tapered walls so that the lobes and contiguous portions of the walls deform in radial compression upon reaching a predetermined preload and displace radially inwardly while the central portions of the walls deform radially outwardly, but do not interfere with the tool that sets the nut.
