An anti-slip fastener remover tool includes a torque-tool body, a plurality of paired engagement features, and an intersection point. 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, a cavity section, and a connector 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 sections of the first engagement feature and the second engagement feature are oppositely positioned of each other about the cavity sections of the first and second engagement features.

An insulated screwdriver includes: an insulator, a first metal sleeve, a second metal sleeve, an insulated sleeve, and a handle. The insulator has a first connecting portion and a second connecting portion. The first metal sleeve is disposed on the first connecting portion of the insulator. The second metal sleeve is disposed on the second connecting portion of the insulator, and the second metal sleeve and the first metal sleeve are insulated. The insulated sleeve covers the insulator, the first metal sleeve, and the second metal sleeve. The handle has an accommodating hole for accommodating the insulated sleeve. According to the insulated screwdriver of the present invention, because the first metal sleeve and the second metal sleeve are insulated, there is no electric shock danger for a user, and safety in use of the insulated screwdriver of the present invention may be improved.

A socket having an offset drive keyway for transmitting torque to asymmetric fastener heads to facilitate their rotation by applying torque across the fastener end to minimize stress on the fastener end-fastener shaft joint.

A grip device for hexagonal wrenches includes a body, a rotary member, a resilient member and a fastening member. The body includes an engaging portion which includes multiple recesses, multiple first slots and an axle. The rotary member is rotatably and movably mounted to the axle. The rotary member includes a first room defined in the inner periphery of the passage through which the axle extends. A first shoulder is formed between the first room and the passage. The resilient member is mounted to the axle and the fastening member is connected to the axle. An L-shaped tool has the first section thereof received in one of the recesses and the first slot of the recess. When the rotary member is moved toward the engaging portion, the first section is inserted into the first slot. The L-shaped tool is restricted by the rotary member and used as a T-bar tool.

A pair of screwdrivers each having a handle, a nondetachable outer shaft, a detachable inner shaft, and at least two detachable double-ended screwdriver bits. Each screwdriver handle is formed having a hollow space configured to substantially house the outer screwdriver shaft, the inner screwdriver shaft, and the at least two double-ended screwdriver bits of the other screwdriver, whereby, the pair of screwdrivers may be assembled together when not in use so that the outer shaft, the inner shaft, and the at least two double-ended screwdriver bits of both screwdrivers are substantially non-exposed to prevent the potential for accidental user injury.

Various embodiments of a curved-tip screwdriver bit are presented. The bit may include a shank, a body connected with the shank, and a tip disposed at an end of the body. The tip may include curved blades that project from the end of the shaft. A first curved blade may have a first arc shaped cross section. A second curved blade may have a second arc shaped cross section. A radius of the second arc-shaped cross section may be greater than a radius of the first arc-shaped cross section of the first curved blade.

Driver support assemblies to work in concert with a setup assembly are provided. Setup assemblies to work in concert with a driver support assembly and a cutting assembly are provided. Cutting assemblies configured to work in concert with a driver support assembly are provided. Driver tip cutting assemblies are provided. Methods for cutting the tip of a driver shaft are provided.

A driving tool includes a body portion, a driving portion, and a neck portion. The driving portion defines a reference rotating axis. A distal end of the driving portion opposite to the body portion is provided with a front driving face having a first width in a radial direction of the reference rotating axis. The neck portion is disposed between the body portion and the driving portion and has a second width in the radial direction of the reference rotating axis. The second width is less than the first width.

A driving tool includes a body portion, a driving portion, and a neck portion, wherein the driving portion defines a reference rotating axis, wherein distal end of the driving portion opposite to the body portion is provided with a front driving face having a first width in a radial direction of the reference rotating axis, wherein the neck portion is formed between the body portion and the driving portion and has a second width in the radial direction of the reference rotating axis, wherein the second width is less than the first width.

A fastener system includes a fastener and a driver, each of which have three alternating lobes and troughs that define the drive surfaces. Each alternating lobes and troughs is defined by an outer radius portion, a drive side transition, an inner transition radius, and a reverse drive portion. The fastener recess and the driver each also have a side wall defined by the outer transition radius that tapers at a taper angle relative to a rotational axis. The fastener side wall may taper at about 60°. The driver side wall may taper at about 60°. Alternatively, the driver side wall may taper at an angle at least 10° less than the taper angle of the recess side wall, such as 42°. The drive side transition defines a drive angle, which may be between 0° and 5°.
