An impact driver includes a hammer that is rotated by a motor and an anvil configured to be struck by the hammer to rotate the anvil about a rotational axis. A hammer case houses the hammer. Two or more bearings are provided inside the hammer case and support the anvil. To inhibit vibration of the anvil during operation, the bearings may be differing types, such as a regular ball bearing and an angular contact ball bearing, and/or the bearings may have different inner and/or outer diameters. A contact member, such as an O-ring, may be disposed in an insertion hole of the anvil to reduce vibrations that are transmitted to the tool bit.

An adjustable impact wrench and ground anchor assembly including a torque bar having a plurality of apertures disposed therein, where the plurality of apertures have a first and second diameter, a wrench shaft having a first and second end, a chuck arranged at the first end, a handle arranged at the second end, where the wrench shaft is arranged to engage one of the first diameter apertures of the plurality of apertures therein, a clamp, said clamp arranged to accept said wrench shaft through an aperture disposed therein, a pin arranged to engage a pin aperture of the wrench shaft and is further arranged to sandwich the torque bar between the pin and the clamp, a plurality of spikes arranged to engage the second diameter of apertures of the plurality of apertures, and a clip arranged to engage one of a pair of end apertures of the plurality of apertures.

A manual impact driver for aiding the removal of a threaded fastening member from a structure, is disclosed having a longitudinal axis (L), the manual impact driver including a body having a first end and a second end and a sliding member configured to be coupled to the body at the second end. The impact driver is movable between a first configuration, upon impact at the first end of the body, a linear impact force is translated along the longitudinal axis (L) from the first end of the body to the sliding member and a second configuration, upon impact at the first end, the linear impact force produces a torque, about the longitudinal axis (L), at the sliding member. The impact driver is operable to switch between the configurations upon rotation, by a user, of the body with respect to the sliding member.

A handheld guide for advancing and installing a decking fastener with an elongate track with a rail and an advancement member. The advancement member carries a pivoting pawl with an engagement surface for advancing fasteners forward through the track to an installation position with a frontmost fastener aligned with a screw guide for driving a screw through the frontmost fastener. The rail has a ramp transitioning to a cliff and a lower ledge such that the frontmost fastener is maintained forward of the cliff above the ledge in the installation position. The pawl pivots to disengage from the fasteners when the advancement member moves rearwardly along the track.
