A socket structure includes a socket body, an O-ring, and a carbon-fiber tube. The socket body includes a driving section and an acting section coaxially connected to the driving section. The driving section has an outside diameter greater than an outside diameter of the acting section and a stepped portion is formed in outer circumference between the driving section and the acting section. The driving section and the acting section have end faces that are recessed inwardly to form a driving hole and an acting hole, respectively. The outer circumferential surface of the acting section is formed with a circumferential groove in which the O-ring is received. The carbon-fiber tube is fit over the outer circumferential surface of the acting section of the socket body and has an end in abutting engagement with the stepped portion and an internal circumferential surface in contact with the O-ring.

A compact, lightweight, universal multi-functional tool that can be used on the fly to adjust and repair surfboards and skateboards is disclosed. The tool includes a housing and an adjustment member. The housing comprises an elongated cylindrical member having a first elongated cylindrical member end and an opposing second elongated cylindrical member end; a first socket head integrally connected to the first elongated cylindrical member end, the first socket head defining a first hexagonal socket; a second socket head integrally connected to the second elongated cylindrical member end, the second socket head defining a second first hexagonal socket; and a cavity extending horizontally through the first socket head, the elongated cylindrical member, and the second socket head. The adjustment member, configured to be received within the cavity, the adjustment member comprises a first arm; and a second arm, the second arm integrally connected, and perpendicular to, the first arm.

A wrench may include a head, a drive tang that engages a work piece, a locking detent operably coupled to the drive tang, and a release button configured to control operation of the locking detent. The release button may be movable between a locked position where the locking detent locks the work piece to the drive tang and an unlocked position where the detent permits removal of the work piece from the drive tang. The wrench may also include a slide lock member configured to slide along a second direction between an engaged position and a disengaged position. In the engaged position, the slide lock member may prevent movement of the release button, and, in the disengaged position, the slide lock member may be disengaged from the release button to permit movement of the release button from the locked position to the unlocked position.

Methods and devices for providing a threaded male member for a fastening arrangement are disclosed. The threaded male member can include at least one reaction portion at or towards at least one respective end of the threaded male member for use in reacting applied torque during tightening or releasing an associated nut of the fastening arrangement. The at least one reaction portion can be a permanent feature of the threaded male member and can remain part of the threaded male member after said tightening to a target torque.

A cartridge tool set comprising a body having a joint portion at each end of the body, the joint portion having a screw hole axially recessed on the end face of the joint portion, the screw hole having a screw surface formed on the inner surface of the screw hole; and a tool portion detachably connected to a tool member.

A clench wrench includes a structure defining a first body defining a handle and a second body integrated with the first body and defining an engaging head respectively. The second body has two opposite sides with one side defining a front side and the other side defining a back side respectively and includes an engaging space. The engaging space extends through the front and back sides, and an opening is defined on both the front and back sides. One of the front and back sides includes a clenching member of a clenching device connected thereto. The clenching member is selectively movable between a first position blocking the opening of the engaging space adjacent to one of the front and back sides and a second position in which the opening of the engaging space adjacent to one of the front and back sides is not blocked.

A non-magnetic locking sleeve includes an engagement unit disposed in a body which includes a locking socket and a positioning groove. The locking socket is enclosed by a plurality of peripheral walls connected one after another for holding a fastener. The positioning groove is annularly recessed into the peripheral walls for receiving the engagement unit. Preferably, an intersection of two adjacent peripheral walls forms a recessed portion whereby the fastener is held by the peripheral walls more tightly while inserting into the locking socket. A periphery of the engagement unit can be formed with a rough surface or at least one engaging surface to increase a contact area between the engagement unit and the fastener. Accordingly, the fastener is firmly positioned by the locking sleeve to increase the stability of a following fastening operation executed by the fastener.
