A bi-directional back stopping clutch having improved output pins connecting between brake shoes and an output member. During driving, the output pins transfer torque to the output member. When a sufficient back driving force is applied to the output member, the output pin is skewed to move the brake shoes into forceful contact with a brake drum surface. The contact surfaces between the pins and the brake shoes are flat meeting surfaces, and the pins may be spaced apart by including at least one spring or a combination of springs and spacers. The inner surface of the input yoke and the output member openings are laser hardened. The output member and the input member may be provided with a dual keyed hub at both ends, with the hub formed by machining a bore through the part and cutting the keys by broaching.
