A temporary tightening tool includes a grip part and a socket part into which a bolt head part is inserted. The socket part is formed in a shape of a hexagonal tube surrounded by six side walls, a hook part, which is a leaf spring part, is formed in each of alternate three side walls among the six side walls, and a thick torque transmission part is formed in each of three remaining side walls without the hook part. When the bolt head part is inserted in the socket part, the hook part is elastically deformed, and holds the hold bolt head part with restoring force. Torque input into the grip part is transmitted to the bolt head part from the torque transmission wall.

A tool for manipulating flexible and non-flexible fastening devices. The tool assembly has a flexible rod for insertion into the distal end of the fastening device. A handle assembly interacts with proximal end of the flexible rod and the proximal end of the fastening device to control of the fastening device by initiating rotation at the distal end of the fastening device.

The present invention discloses a manual tool having a retractable tool member, which further comprises a handle and a linkage member. The tool member is configured to be retractably moveable relative to the handle between an operating state and a retracting state under the driving of the handle and the linkage member.

A hex wrench improved structure comprises a body, one end thereof has six equally divided planes, an abutting angle is formed between each of the two planes, at least one of the planes is disposed with a groove, the groove has two inclined surfaces, one side of each of the two inclined surfaces is connected to the abutting angle of the two planes, another sides of the two inclined surfaces are connected to each other, and an obtuse angle is included between the two inclined surfaces; thereby, the hex wrench can be pressed tightly against an inner wall surface of a hole in a screw for inserting a cap screw tool to apply force, so that the hex wrench is not easy to slip, and it is easier to turn and lock or adjust the screw.

Adjustable fastener tools are provided for engaging socket heads. The tool includes a support member, multiple engagement fingers, and an adjustment mechanism. The support member has multiple radially-extending tracks, and a central opening, and the fingers are associated with, and slidable along, the radially-extending tracks. The fingers include at radially inner ends jaws with respective contact surfaces for engaging the socket head. The adjustment mechanism resides, at least in part, within the central opening in the support member, and couples to the fingers. The adjustment mechanism includes an actuating member and multiple hinged trusses. A hinged truss of the trusses is hingedly coupled at one end to the actuating member and hingedly coupled at an other end to a respective finger of the engagement fingers. Movement of the actuating member results, via the hinged truss, in slidable movement of the respective finger along its associated radially-extending track.

An anti-slip fastener remover tool includes a torque-tool body and a plurality of paired engagement features. The plurality of paired engagement features that grips the lateral surface of the stripped fastener head is radially positioned around a rotation axis of the torque-tool body. The plurality of paired engagement features, wherein each paired engagement feature is offset by 30 degrees, comprises a first engagement feature and a second engagement feature. The first engagement feature and the second engagement feature each comprises a bracing section and a cavity section that are adjacently connected to each other. The cavity section of the first engagement feature is adjacently connected to the cavity section of the second engagement feature. The bracing section of the first engagement feature and the bracing section of the second engagement feature are oppositely positioned of each other about the cavity sections of the first and second engagement features.

A hand tool comprising a head portion, a shaft, and a grip component is provided. The grip component and the shaft form a handle of the hand tool. The grip component is a reverse-molded component formed by: forming the external portion of the grip component by molding a first thermoplastic elastomer (TPE) material or thermoplastic urethane (TPU) material into a shell that surrounds a first cavity; after forming the external portion; placing the shaft into the first cavity; and, after the external portion is formed and the shaft is placed into the first cavity, forming the inner portion of the grip component by injecting a second TPE material or TPU material into the first cavity and onto the shaft. The first TPE or TPU material has a first level of hardness, and the second TPE or TPU material has a second level of hardness lower than the first level.

A fastener extractor device for removing fasteners and disengaging the extractor from the so engaged fastener. The extractor includes a threaded main body with a hex drive head end portion and oppositely disposed elongated tool engagement hex body with multiple bracing sidewalls with independent contoured fastener engagement channels for fastener insertion and continued rotational removal. A tubular hex surface extractor nut is threadably disposed on the main body member for reversed thread rotation advancement to physically disengage the tool engagement body from the removed fastener.

A grip device includes a tubular body, an adjustment member, a left slide and a right slide. The body includes a passage, a guiding slot, a recess and a groove. The adjustment member includes threaded portion. The left slide is slidably located in the groove and includes threads which are engaged with the threaded portion of the adjustment member. When the adjustment member is rotated relative to the pin, the threaded portion of the adjustment member drives the threads of the left slide to move the left slide toward the right slide so as to clamp the hexagonal wrench.
