A power tool accessory is adapted to be mounted to a spindle of a power tool having a power tool housing. The power tool accessory includes a hub, a working element, a bolt, and a nut. The hub includes a first surface and a second surface that is opposite to the first surface. The hub further includes an opening extending through the hub. An axis of rotation of the hub is defined through the opening. The working element is connected to the hub. The bolt includes a head having a cross-section that is greater than the opening of the hub. The bolt further includes a shaft adapted to extend through the opening of the hub. The shaft is adapted to be received on the spindle of the power tool. The nut cooperates with the bolt and includes a head and an aperture extending through the head. The head of the nut has a cross-section that is greater than the opening of the hub. The aperture of the nut is adapted to be received on the shaft of the bolt. The bolt and the nut are mounted to the hub such that when the power tool accessory is mounted to the power tool for operation, the position of the hub relative to the power tool housing is substantially the same regardless of whether the first surface or the second surface of the hub is adjacent to the power tool housing.
