An improved open-ended wrench that is adaptable for engaging hexagonal head nuts with non-specific engagement surfaces. The wrench provides a handle with an open working end having opposed flat jaw working surfaces with a positional work piece engagement cavity there between. A contact enabling contoured notch cutout in each flat inside working surface with corresponding standard and non-standard support and torque engagement surface respectively inwardly from the junction of the concave cavity portion.

An anti-slip torque tool with integrated engagement features includes a torque-tool body, at least one pair of diametrically opposing engagement features, and an intermediate feature. The pair of diametrically opposing engagement features includes a first opposing feature and a second opposing feature and functions as engagement features around the head portion of the fastener that needs to be removed. The first opposing feature and the second opposing feature are radially distributed around a rotational axis of the torque-tool body. The first opposing feature and the second opposing feature are terminally connected to each other by the intermediate feature. The torque-tool body is outwardly extended from the first opposing feature, the second opposing feature, and the intermediate feature thus delineating an opening to receive the head portion of the fastener.

A locknut wrench and method. The wrench may include a handle extending along an axis and having opposite sides; a first hook portion at one end of the handle, the first hook portion extending from the axis to a first hook member about a first angle, the first hook member being selectively engageable with a tab of a locknut; and a second hook portion at an opposite end of the handle, the second hook portion extending from the axis to a second hook member about a second angle different than the first angle, the second hook member being selectively engageable with a tab of a locknut, the second hook portion including a tooth positioned on a side of the handle opposite the second hook member, the tooth extending from the axis to an end about a third angle.

An apparatus for adjusting a height adjustable leg for supporting a cabinet, appliance or structure is described. The apparatus includes a foot of a height adjustable leg and a tool comprising a driving member and a torque input for applying torque to the driving member. The foot includes a rotatable foot part with a driven member and a base part to support the rotatable foot part on a floor or supporting surface. The tool and the foot are complementarily adapted to releasably maintain engagement between the driving member and the driven member to allow the driving member to drive the driven member to rotate the rotatable foot part about a longitudinal axis of the leg for height adjustment of the leg.

A wrench for removing and installing a water tank in a plumbing and/or heating system as shown and described herein can include, an elongated handle portion having opposed proximal and distal ends, and a crescent shaped head portion operatively associated with the distal end of the elongated handle portion. The head portion can include an opening that is adapted and configured to match the hexagonal dimensions of two different common threaded connectors.

A quick-turning wrench includes a driving end with a first jaw and a second jaw. The first and the second jaws respectively have a first and a second side, which face one another. The driving end defines an engaging space between the first and the second jaws. The driving end has a first grip-surface section, a second grip-surface section, and a third grip-surface section. The engaging space is partially delimited by the first, the second, and the third grip-surface sections. The first grip-surface section is adjacent to the first side and extends along a flat first phantom surface. The second and the third grip-surface sections are adjacent to the second side and respectively extend on a flat second phantom surface and a flat third phantom surface.
