A ratcheting pliers device for extracting a fastener from a substrate includes a first arm, which is pivotally engaged to a second arm to define a pair of jaws and a pair of handles. Each jaw has a cutout for insertion of a head of a fastener. A ratchet bar, which is pivotally engaged to the first arm, has a plurality of first teeth extending from its upper surface. A biaser engaged to the first arm and the ratchet bar is positioned to pivot the ratchet bar into engagement with a second tooth that is coupled to the second arm. The second tooth sequentially engages the first teeth as the first arm and the second arm are motivated to a proximate orientation, concurrently with the jaws being motivated to a closed configuration. The jaws are prevented from opening while a user pulls on the handles to extract the fastener.

A plug for retaining a filter screen in a fluid port of a servovalve, comprises an annular body, the annular body comprising: opposed first and second axial end surfaces, a radially inner surface extending between the first and second axial end surfaces, a radially outer surface extending between the first and second axial end surfaces and at least one recess formed in the radially inner surface for receiving a tool for removing the plug from the port. A tool for removing the plug comprises a pair of handles pivotally mounted to one another about a pivot, each handle having a plug gripping portion extending therefrom beyond the pivot, each plug gripping portion comprising an outwardly projecting tooth for engaging in the recess of the plug when the plug gripping portions are moved apart by operation of the handles.

The invention relates to a hand pliers tool which might be embodied as crimping pliers, tube pressing pliers or cutting pliers. According to the invention, pliers pivoting parts are not (exclusively) connected to each other for being pivoted by bearing bolts arranged in bearing bores. Instead, pivot bearings are formed by bearing lugs having edge openings by which it is possible to insert a bearing pin into the bearing lug.

A hand tool and a wire stripper. The hand tool may include a first jaw portion and a second jaw portion having a spring constant more than about 2,225 lbs./in., measured when a force is applied in a direction parallel to the pivot axis to an associated jaw tip with a pivot member being held. The hand tool may include a jaw portion having a gripping surface and an angled wall connected to a side wall and defining a wire stripping portion, the wire stripping portion including a cutting edge and a recess defined in the angled wall, the recess extending from the cutting edge to an end at the one of the side walls, the angled wall being arranged non-parallel to the gripping surface and non-perpendicular to the side wall. The wire stripper may be a forged wire stripper including jaws defining a stripping aperture for Romex® NM wire.

A pair of pliers has a first and a second plier leg, which are mounted so as to be rotatable relative to one another in a joint region and which form gripping regions on one side of the joint region and a plier jaw on the other side. A locking part fixes position of the pliers. The locking part is rotatably mounted on the first plier leg at a transition between the gripping region and the joint region of the plier leg, and, in the fixed position, fixes the pliers by contact with the joint region of the second plier leg. The locking part, in the fixed position and under load, is in supporting contact both with the joint region of the second plier leg and with the gripping region of the first plier leg in a plane perpendicular to the axis of rotation of the plier legs.
