Abstract: A driver has a deltoid wrenching and deforming socket in the form of an equilateral triangle with rounded corners. Flats of the socket between the apexes of the triangle bear on lobes of a collar to thread the collar onto a pin in the making of a joint. At a predetermined clamp-up load on the joint, the flats of the deltoid socket crush the lobes plastically and force material of the collar radially inward of the lobes into locking engagement with the pin. Thereafter the socket can rotate freely on the collar. A pilot section of the deltoid socket cooperates with a corresponding section of the collar to keep the driver from canting off axis. Reliefs with cylindrical surfaces in the sides of extensions of the flats define piloting surfaces of the pilot section.
