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.

An electrically isolated adapter may include a drive body made of first metallic material extending along a common axis, a driven body made of a second metallic material extending along the common axis, and an isolation assembly formed of insulating material disposed between the drive body and the driven body. The drive body may include a drive head configured to interface with a socket or fastener. The insulating material has a resistance to electrical current that is higher than the resistance to electrical current of at least one of the first metallic material and the second metallic material. The driven body may include a drive receiver configured to interface with a protrusion of a driving tool. A portion of one of the drive body or the driven body is received inside a portion of the other of the drive body or the driven body such that the drive body and driven body overlap each other along the common axis.

An anti-slip fastener remover tool includes a torque-tool body, a plurality of paired engagement features, and a plurality of intersection points. 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 torque-tool body is inwardly extended from an outer wall of the torque-tool body to the plurality of paired engagement features. Each paired engagement feature is offset by 30 degrees, comprising a first engagement feature and a second engagement feature. The first engagement feature and the second engagement feature each comprise a bracing section, a cavity section, and a connector section. The cavity sections of the first and second engagement features are adjacently connected to each other. The bracing sections of the first and second engagement feature are oppositely positioned about the cavity sections of the first and second engagement features.

A tool for torquing a regulator onto a cylinder of a portable cylinder assembly. The tool includes a nut and a socket. The nut is configured to fit around a body of a regulator of a portable cylinder assembly. As such, the nut has a first set of grooves that avoids one or more valve assemblies on the body of the regulator. The socket has a cavity extending therethrough such that the cavity consists of three sections: a top section, a middle section and a bottom section. The top section of the socket is configured to be coupled to a device that applies a torque force on the socket. The middle section of the socket is configured to avoid a case of the regulator which is disposed above the body of the regulator. The bottom section of the socket is configured to be coupled to the nut.

A extractor insert may a body and a securing lip. The body may have a fastener engagement recess. The securing lip may extend radially away from a central axis beyond an exterior of the body. The fastener engagement recess may be an internal channel through the body and is open at a driven end and a drive end. Engagement ribs may extend from internal sidewalls of the body towards the central axis, and each engagement rib may include an apex that extends along a length of the engagement rib. Each engagement rib may have an opposing engagement rib such that apexes of the opposing engagement ribs may be disposed on a common plane with the central axis. Further, each apex may taper at a taper angle such that a distance between apexes of opposing engagement ribs is largest at the drive end and smallest at the driven end.

A wrench head for a universal wrench is disclosed that may include a housing having an upper portion and a lower portion. The wrench head may further include a base plate positioned inside the housing towards the upper portion of the housing, and a plurality of push-rods positioned inside the housing. The wrench head may further include a resilient member positioned inside the housing between the base plate and the distal end of each of the plurality of push-rods. In the default position, the resilient member biases each of the plurality of push-rods, and in the retracted position, the proximal end of each of the plurality of push-rods is pushed against the resilient member to be received along with a portion of the resilient member by a compartment of the plurality of compartments defined at the bottom surface of the base plate.

A socket includes a socket body, a teeth structure, and a stopping structure and is engageable with a tool member. The socket body has an opening and an inner wall. The teeth structure is disposed on, and along the circumference of, the inner wall of the socket body and includes alternating inner teeth and concave portions. The stopping structure is disposed on, and along the circumference of, the inner wall of the socket body, is farther away from the opening than is the teeth structure, and includes a through hole and an inner surrounding wall. The through hole corresponds to the opening and is surrounded by the inner surrounding wall, which has a thickness. The distance from each concave portion to the hole wall surface of the through hole is defined as a stopping distance to be considered in relation to the thickness of the inner surrounding wall.

An erosion control securing apparatus and method is disclosed. For example, an erosion control securing device is provided that includes a main shaft with a hexagonal-shaped head portion at its proximal end and a coil portion at its distal end. In one example, the coil portion of the erosion control securing device includes three turns. Further, a method of using the presently disclosed erosion control securing device for securing erosion control products is provided.

An anti-slip fastener remover tool includes a torque-tool body, a plurality of paired engagement features, and a plurality of intersection points. 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 torque-tool body is inwardly extended from an outer wall of the torque-tool body to the plurality of paired engagement features. Each paired engagement feature is offset by 30 degrees, comprising a first engagement feature and a second engagement feature. The first engagement feature and the second engagement feature each comprise a bracing section, a cavity section, and a connector section. The cavity sections of the first and second engagement features are adjacently connected to each other. The bracing sections of the first and second engagement feature are oppositely positioned about the cavity sections of the first and second engagement features.
