Abstract: An autofeed attachment (4) for a screw-driving apparatus (2) includes a base casing (30), a feeder casing (32) slidably mounted on the base casing (30) and a wheel (72) rotatably mounted within the feeder casing (32). When rotated in a forward direction, the wheel (72) advances a screw strip (50), which has a plurality of screws (52) coupled by a connecting strip. A wheel forward-direction rotating mechanism (60, 64, 66, 68) rotates the wheel (72) in the forward direction and restricts rotation of the wheel (72) in a reverse direction opposite the forward direction. A wheel-release mechanism (70, 107, 117) releases the restriction placed on rotation of the wheel (72) in the reverse direction. The wheel forward-direction rotating mechanism and the wheel-release mechanism are disposed, at least partially, inside of the wheel (72) and/or the rotational axis of the wheel (72) intersects a release button (107) of the wheel-release mechanism.
