The apparatus also includes a locking member configured to engage the second jaw when the second jaw is rotated away from the first jaw and retain the second jaw in a rotated position.

In a continuous screw tightening machine with washer stacking supply mechanism, in conjunction with retreating of a tightening machine, a washer is placed on a seat surface portion of a washer feeding body of a washer sequential supply mechanism and reliably supplied to a tightening possible position one by one and the one screw is supplied by a screw sequential supply mechanism between the washer and a bit so as to be in concentric arrangement, in conjunction with advancing of the tightening machine, the washer sequential supply mechanism is set to a feeding preparation attitude of the subsequent washer, and the screw sequential supply mechanism is constituted to be set to a feeding preparation attitude of the subsequent screw, and the screw is tightened and fixed together with the washer at the tightening target spot by rotation/driving of the bit advanced to the tightening possible position by a driving machine.

A screwing device, which serves for screwing boards (2) onto underlying crossbeams (3) in such a way that the screws are screwed tilted in from the edges (5) of the boards (2). The screwing device includes a base (7) with an oblong foot (8) which in use stands on the upper side of the boards (2), two arms (9) extending tilted out from each their end of the foot (8), and two opposite screw drivers (10), which are mounted on each their arm (9) and each is arranged with means for conveying a disposable belt (34) of releasable screws (6) and for stepwise screwing in screws (6) from the belt (34). With the present invention, the components of a terrace can be screwed faster together than hitherto known, and at the same time the terrace obtains optimal strength.

The present invention provides a screw feeding/fastening unit of a continuous screw fastening device which enables assuredly pulling screws out of a screw strip in tandem with a screw fastening operation even in case of using the screws each of which has, e.g., a flat shape below its head portion.

A screw feeding/fastening device of a continuous screw fastening device according to the present invention is a screw feeding/fastening unit 1 of a continuous screw fastening device which fastens screws 4, and it is configured to include a screw strip binding piece unbinding section 51 which supports a screw strip guide unit 2 to be rotatable in a direction orthogonal to a longitudinal direction of a bit by a shaft body 53 provided at a position before a feed case 22 in a feeder unit 21 and to be restorable to its original position by a spring 54, has on the screw strip guide unit a turning receiver 6 which abuts on a part of a slide frame and receives turning force at the time of a slide operation of the slide frame 31 toward the screw strip guide unit, and turns the screw strip guide unit together with the turning receiver around the shaft body as a spindle in a direction along which a tip side gets away from a screw at the fastening acting position to impart unbinding force to a screw strip binding piece 3a at the time of fastening the screw.

A fastener installation tool and related method are provided for installing fasteners in boards. The tool can include a feed mechanism that automatically and sequentially feeds collated fasteners to a nose assembly. The nose assembly can include a guide having an alignment projection extending downwardly from the guide, and configured to engage a board corner and/or side surface, so as to align an angled bore through which fasteners are guided with the board corner and or side surface. The nose assembly can include a magnetic element located adjacent a path on which the collated fasteners are advanced. The magnetic element can exert a magnetic force on an individual fastener, aligning it for precise entry into the angled bore. The nose assembly can include a guide pocket to positively constrain a fastener as it rotates to ensure a desired advancement trajectory. A related method of installation is provided.

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.

A fastener delivery system includes an escapement mechanism configured to control dispensing of associated fasteners located in a column one associated fastener at a time and a rotate and present apparatus operable with the escapement mechanism. The apparatus is configured to rotate between a fastener receiving position and a fastener loading position. In the fastener receiving position the apparatus is adapted to receive each associated fastener released from the escapement mechanism, and in the fastener loading position the apparatus is configured to present each associated fastener to an associated fastener installation device. The escapement mechanism is adjustable in a height direction relative to the apparatus.

A fastener assembly includes an elongated fastener body with a head end part. A propelling member supported on the fastener body, wherein the propelling member has a lengthened shape, wherein a portion of the lengthened shape extends around the head end part of the fastener body. A method of propelling the fastener assembly is also provided.
