A pre-assembled female mould arrangement for being installed on a moulding machine, the pre-assembled female mould arrangement comprising: an annular forming element, extending about an axis and delimiting a forming cavity about said axis; a plate element, which delimits the forming cavity transversely to said axis; a peripheral annular component that surrounds at least partially the annular forming element; a supporting base;
a fastening element which is so mounted as to render the annular forming element fixed relative to the plate element.

Interchangeable reaction washer initially penetrates with outward bottom serration edges only during manual pre tightening. Slippage is thereby avoided at begin of the consecutive power torque wrench assisted full tightening of the nut and/or bolt head resting on it. As the load ramps up, the reaction washer flattens out and the bottom serrations gradually penetrate radially inwards. Reaction and actuation sockets of varying sizes matching a broad range of reaction washers and nut and/or bolt heads may be interchangeably snapped on a reaction coupling connected to the torque wrench housing. A clearance undercut underneath the reaction washer torque receiving flanges absorbs eventual debris to further assist unimpeded and fast coupling of the system. Radially oriented contact faces between reaction washer and reaction socket provide a snug contact unaffected by their toroidal movement during washer flattening and a force transfer free of radial force components.

A valve including a body having an inner central orifice and a chamber, a piston formed by a rod and by a head mounted in the chamber, the rod extending outside the body and moving in a bore of an application system. The valve includes a first sealing device around the rod on one side of the valve where the rod extends outside the body, part of the chamber being filled with a pressurized control fluid to obtain movement of the piston against the force of a spring housed in the body. The valve includes a second sealing device around the rod, between the first sealing device and the chamber. The valve includes a vent duct in the rod that communicates with the inner central orifice between the first and second sealing devices and emerges in the open air or in part of the chamber communicating with the open air.

Valve for a system for applying a covering product, including projecting or recessed shapes on a peripheral part, configured to cooperate with projecting or recessed shapes of a dedicated mounting and dismounting tool, these projecting or recessed shapes of the valve being configured to transmit a rotational movement to the valve, and to be secured to the tool. The projecting or hollow shapes of the valve include a first peripheral profile having at least one planar surface, and a second peripheral profile located behind the first profile relative to an outer end of the valve. The second profile has at least one first planar surface aligned with the planar surface of the first profile, and at least one second planar surface angularly offset relative to the planar surface of the first profile, such that the second planar surface of the second profile forms a shoulder relative to the first profile.

A multifunction socket tool is provided that has first socket component for engagement with a first size drive portion of a threaded fastener, and a second socket component for engagement with a second size drive portion of a threaded fastener, with the second size being smaller than the first size The second socket component translates from a first position where it can torque a drive portion of the second size to a second position where the first socket component can torque a drive portion of the first size. The first socket component includes a first pair of opposed slots for receiving and torqueing the eye of an eyebolt, and the second socket component includes a second pair of opposed slots for aligning the first pair of slots with the eye prior to engagement of the eye by the first pair slots.

A faucet installation tool includes at least two coupling units. Every adjacent two of the coupling units are detachably connected together. A hollow area is formed between middle portions of the coupling units. Tops of the coupling units are formed with a first socket portion. The first socket portion is configured to receive a lock nut used for installing and fixing a threaded connecting pipe of a faucet, improving the connection strength between the first socket portion and the lock nut. The faucet installation tool does not require a large lateral space and is convenient to tighten the lock nut when in use.

A torque tool is provided, including: a barrel; a first member disposed to the barrel, including at least one first engaging portion; a second member disposed in the barrel, including at least one second engaging portion, the at least one second engaging portion and the at least one first engaging portion being disengageably engaged with each other; an elastic mechanism, disposed inside the barrel and including elastic arms, the second member being configured to abut and radially deform the elastic arms; wherein when there is a torsional three greater than a preset torque value between the at least one second engaging portion and the at least one first engaging portion, the second member urges and radially defines the plurality of elastic arms so that the at least one second engaging portion and the at least one first engaging portion are relatively slipable and disengageable.

A self-adjusting-size socket formed as a pair of coaxial tubes in rotatable relationship to one another, the innermost tube having a limited directional distance and independently rotational relationship with the outer tube by rotating along a mated set of threaded structures on immediately adjacent sides of the coaxial pair of tubes. The inner tube is a deep well chamber having a tool receiving end and a fastener receiving end, with an annular array of independently pivotable fingers arranged about an internal perimeter of the inner tube at the fastener receiving end. Rotation of the inner tube pushes a lowermost portion of the inner tube against the fingers, pushing them into the deep well chamber and around an irregularly shaped bolt or nut style fastener, gripping the fastener and allowing a user to remove or reinstall the fastener. The fingers self-adjust around the fastener.

A bidirectional extraction socket may include a driven end configured to receive drive power from a driving tool, a drive end configured to interface with a fastener, and a body portion extending between the driven end and the drive end about an axis of the extraction socket. The drive end includes a fastener engagement recess extending into the body portion and coaxial with the body portion. The fastener engagement recess is configured to engage with the fastener such that the fastener is drivable in either a clockwise or a counterclockwise direction while avoiding contact with corner portions of the fastener.

A nut driver includes an elongate drive shank and a reversible socket. The socket has a first hex socket opening sized to engage a hexagonal profile of a first size, and a second hex socket opening sized to engage a hexagonal profile of a second size that is larger than the first size. The socket is mountable on the drive shank in either a first orientation that presents the first hex socket opening for use, or a second orientation that presents the second hex socket opening for use. Additionally, in the first orientation, the socket is mountable in either a screw head receiving position or a drive bit receiving position.
