A folding flex ratchet having a handle that is joined to a ratchet head by an offset hinge that allows the handle to be selectively folded between an extended position for applying greater torque and a folded position in which the ratchet operates in spaces where access is minimal, somewhat like a palm ratchet. The ratchet head may include a generally L-shaped neck that provides an offset handle connection point that is offset in two directions from the ratchet head, both rearwardly and longitudinally. The handle, ratchet head and offset hinge are configured so that, when in the folded position, the handle is approximately centered over the ratchet head and the handle extends substantially parallel to the ratchet head.

A hand tool for fastening a fastener, such as a screw. The hand tool comprises a handle and a rotatable fastening head connected to a first end of the handle, and engaged with a manually driven actuator. The hand tool further comprises a fixed fastening head connected to a second end of the handle, which is configured to apply a configurable fastening torque to the fastener The fixed fastening head is selectively pivotable with respect to the handle about an axis parallel to the center axis of the fixed fastening head.

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 screw driver system includes a screw driving bit and a guide clamp. The screw driving bit includes a unitary body having a first end and a second end with a longitudinal axis defined therebetween and an outer surface having a cylindrical portion between the first and second ends. The screw driving bit includes a first circumferential groove and a second circumferential groove that are affixed in coaxially positioned arrangement about the longitudinal axis on the outer surface of the cylindrical portion each having a bottom surface. The bottom surface of the first circumferential groove defines a first outer diameter that is larger than a second outer diameter defined by the second circumferential groove. The guide clamp includes a jaw for holding the screw driving bit. When engaged with the first circumferential groove, the guide clamp prevents rotation of the screw driving bit. When engaged with the second circumferential groove, the guide clamp does not prevent rotation of the screw driving bit.

A screw engagement system comprising a screw and a driver. The screw may comprise a recess in the screw head and a plurality of grooves arranged circumferentially around and formed radially outwardly into the screw head from an inner circumferential surface of the screw head recess. The driver may comprise a driver head having the general shape of a spherical frustum and including a plurality of splines that engage the screw head recess grooves and transmit torque and impart rotational motion to the screw therethrough.

A multi-functional wrench having an adjustable construction and including i) a ratchet mechanism that can be disposed at a plurality of different angular positions with respect to a body of the wrench and ii) a plurality of sockets which are useful for many applications and can accept various bits or tools engageable within the socket. The multi-functional wrench has a body that is archial or curved in shape which is a particular benefit when the wrench is used in difficult to reach areas.

An adapter for a bearing race and seal driver tool that allows the tool to be used in hard to reach applications. The adapter connects to a driver and a handle at a non-zero angle, for example a right angle, to allow the adapter to be struck at a face of the adapter rather than the handle to be struck at an end of the handle. A pocket is included at one or more connection points between the adapter and the handle or driver to resist rotational movement of the handle or driver.

A module for transmission of a force including two toothed wheels which are connected to a main shaft; a first ratchet holder and a second ratchet holder which are provided with a first ratchet and a second ratchet, and are designed such, when they are actuated, to rotate the toothed wheels by support of the ratchet concerned against a tooth of the toothed wheel; a first cam and a second cam, which are designed to actuate respectively the first ratchet according to a first angular course around an axis YY of the first cam, and the second ratchet according to a second angular course around the axis YY of the second cam, which is different from the first angular course.

A screw driver system includes a screw driver and a guide clamp. The screw driver includes a driving bit. The driving bit includes a body having a first end and a second end and an outer surface comprising a cylindrical portion between the first and second ends. The screw driving bit includes a first circumferential groove and a second circumferential groove on the outer surface of the cylindrical portion each having a bottom surface. The bottom surface of the first circumferential groove defines a first outer diameter that is larger than a second outer diameter defined by the second circumferential groove. The guide clamp includes a jaw for holding the screw driving bit. When engaged with the first circumferential groove, the guide clamp prevents rotation of the screw driving bit. When engaged with the second circumferential groove, the guide clamp does not prevent rotation of the screw driving bit.

A method of determining an actual amount of torque and/or angle applied to a work piece by a tool. In an embodiment, the method includes determining a rotational angle, a tilt of the tool, and a measured torque of the tool. The actual amount of torque or angle applied to the work piece is then determined based on the rotational angle, the tilt, and the measured torque.
