Abstract
A cylindrical lock on a door panel has an outside actuating lever and an outside nut. Torque from both the nut and the outside lever is transferred to a substantially planar torque plate engaging the door panel and having a central opening bounded by arcuate edge surfaces spaced away from external threads on the lock hub. The central opening is also bounded by chordal edge surfaces disposed next to chordal surfaces on the lock hub. The nut has chordal surfaces next to the chordal surfaces of the torque plate and has arcuate surfaces close to the arcuate surfaces of the torque plate, all of such surfaces being in the plane of the torque plate.
