A repositionable abrasive disc mounting assembly comprises a backup pad and a clamp assembly. The backup pad has a rotational axis of use and a major surface with projections extending outwardly therefrom. The backup pad further comprises an inwardly facing centrally disposed first fastening member, and also an outwardly facing centrally disposed second fastening member. The clamp assembly comprises inner and outer clamp members for securing an abrasive disc. The inner clamp member comprises an inwardly facing centrally disposed third fastening member adapted to repositionably engage the second fastening member in a discrete number of rotational orientations. The inner clamp member further comprises an outwardly facing centrally disposed fourth fastening member. The outer clamp member comprises an inwardly facing centrally disposed fifth fastening member adapted to securely engage the fourth fastening member. A method of abrading a workpiece using the repositionable abrasive disc is also disclosed.

Aspects of the present disclosure relate to a self-mating fastener that includes a backing having a first side, and a rail element protruding perpendicularly from the first side of the backing. The rail element extends in a longitudinal direction along the backing. The rail element has a base portion attached to the first side of the backing and a cap portion distal from the backing. The cap portion has a cap width that is greater than a width of the base portion and the cap portion overhangs the base portion on opposing sides. The self-mating fastener includes an electrically conductive contact element proximate to the rail element.
