A socket includes two opposite ends and an axis extending between the ends. The socket further includes a small-diameter section in the vicinity of the first end, a large-diameter section in the vicinity of the second end, and a polygonal section between the small-diameter section and the large-diameter section. A circular bore extends in the small-diameter section along the axis. A non-circular bore extends in the polygonal section and the large-diameter section along the axis. Thus, an entire length of the socket and a length of the large-diameter section measured along the axis are rendered relatively small without reducing a depth of the non-circular bore.

A tube clamp socket, including a socket body, including a cylindrical surface, a first slot disposed on at least a portion of the cylindrical surface to receive a first portion of at least one fastener therein, a second slot disposed on at least a portion of the cylindrical surface to receive a second portion of the at least one fastener therein, and a fastener receiving aperture may be disposed within at least a portion of an interior of the cylindrical surface to receive a center portion of the at least one fastener therein, and an attachment body removably connected to the cylindrical surface to contact the first portion and the second portion of the at least one fastener to prevent the first portion and the second portion of the at least one fastener from moving away from the first slot and the second slot.

An engagement structure of a socket wrench contains: a body including a drive head, an accommodation chamber, a ratchet member received, a hexagonal groove, a circular large-diameter notch, multiple recessed, and a hexagonal small-diameter orifice. The hexagonal groove is configured to accommodate a locating sleeve. The locating sleeve includes an upper extension, a hexagonal positioning portion, a hexagonal receiving hole, multiple columns, two opposite central holes, two steel balls, and a slot. The locating sleeve further includes multiple springs fitted on the multiple columns of the multiple cutouts. The upper extension of the locating sleeve is connected with of the hexagonal small-diameter orifice and a hexagonal coupling aperture of a control disc, and a C-shaped retainer is engaged in the slot of the locating sleeve so that the C-shaped retainer abuts against the control disc, thus connecting the ratchet member, the locating sleeve, and the control disc.

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 cam lock chain tool apparatus for safely and effectively installing and removing tire chains includes a receiver body having a receiver front side, a receiver back side, a receiver left side, a receiver right side, a receiver top side, and a receiver bottom side. The receiver bottom side has a receiver aperture dimensioned to receive a standard socket wrench. An extender is coupled to the receiver body. The extender is coupled to the receiver top side. A tab is coupled to the extender. The tab is dimensioned to engage a cam lock for a tire chain.

A ratchet socket may include a main body, and an outer periphery of the main body has ratchet teeth formed in an endless circular pattern to form the main body with a polygonal cross section. The main body comprises a hexagonal inner periphery to form six internal angles and six inner edges. Each of the inner edges has an engaging portion at a middle portion thereof, and each of the inner edges comprises two abutting portions at two sides of the engaging portion between the engaging portion and each of two adjacent internal angles. Each of two recess portions is formed between the engaging portion and the abutting portion to form two engaging teeth on two lateral edges of the engaging portion. Each of the internal angles is curved to form an inclined surface between the abutting portion and the adjacent internal angle.

A wrench includes a ratchet unit located in the head and includes a mount hole. A collar is connected to the head and located corresponding to the mount hole. The collar includes a slot and an aperture. A C-shaped engaging member includes a first end thereof inserted into the aperture. A second end of the engaging member protrudes beyond the collar. The engaging member includes a curved section which is resiliently inserted into the slot. A rotary member is mounted to outer periphery of the collar and includes a notch defined in the underside thereof. The second end of the engaging member is located in the notch and covered by the rotary member. When the rotary member is rotated, the engaging member is deformed to insert or remove the curved section relative to the mount hole via the slot to position a socket in the head of the wrench.

A fastener extractor device for removing seized fasteners and aiding in disengaging the extractor device from said seized fastener afterwards. The extractor device includes a shank body, a drive head, a torque-tool body, a tubular sleeve, an external thread, and an internal thread. The torque-tool body includes a plurality of laterally-bracing sidewalls and an at least one engagement feature. The engagement feature is integrated into a specific sidewall to bite into a sized fastener. The drive head is terminally and concentrically connected to the shank body to receive an external torque tool. The torque-tool body is terminally and concentrically connected to the shank body, opposite the drive head. The tubular sleeve is slidably engaged along the shank body through the internal thread and the external thread to physically disengaged the torque-tool body from a seized fastener.

A striking tool includes an elongated handle having a first end and a second end. The head is attached to or formed integrally with the first end of the handle and defines a striking portion, a claw portion, and a body portion therebetween. The striking tool may have slots, notches, and/or cavities configured to engage fasteners or other objects for applying torsion thereto. A striking member may be removably attached to the striking portion of the head, which may define a nail puller. Attachments, such as an axe head, may be removably attachable to the head of the striking tool.

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.
