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 tool bit for driving a fastener includes a shank having a tool coupling portion configured to be coupled to a tool. The tool coupling portion has a hexagonal cross-sectional shape. The shank also has a head portion configured to engage the fastener. The head portion is composed of powdered metal (PM) steel having carbide particles distributed uniformly throughout the head portion.

The instant invention is directed to a universal bone screw screwdriver and in particular to a universal screwdriver that permits the removal of screws from bone plates that are manufactured by different manufacturers having distinct characteristics. The universal bone screw screwdriver is adapted to removably receive an elongated tool bit having a hollow center. The elongated tool bits correspond to the screw heads of different manufacturers and comprises a torque limiting and locking spring assembly to secure the elongated tool bit to the driver shaft and inhibit over-tightening of the bone screw into the bone or bone plate as the case may be.

A tool bit includes a hexagonal drive portion, a working end, and a shank interconnecting the drive portion and the working end. The shank includes an outer peripheral surface having a curvature in a plane including a central axis of the tool bit. The outer peripheral surface having the curvature includes a length in the direction of the central axis. A ratio of the length of the outer peripheral surface having the curvature to the length of the tool bit is between about 0.2:1 and about 0.7:1.

Fasteners, drivers, and fastener systems constructed wherein example fasteners have driver engageable surfaces on or within a shank tip of the fastener. Example embodiments are included where at least one of the installation and removal surfaces are configured to define a segment of a spiral. Some example embodiments are also included where the installation and removal drive surfaces intersect an enlarged core diameter in an inner transitional surface that extends between the installation and removal surfaces of adjacent wings. Embodiments include fasteners with installation and removal drive surfaces on or within a shank tip of fasteners.

A belt buckle adapted for securing a plurality of tools. The multi-purpose belt buckle system includes a first component for screwing a screw and a second component for holding the first component. The first component is T-shaped and includes various types of screwdriver heads. The second component further includes a slot for holding the first component, at least one open wrench and least one means for connecting a strap/lace.

A tool bit includes a drive portion configured to be engaged by a tool, the drive portion including a first maximum outer dimension, a shank extending from the drive portion and including a reduced outer diameter, and a tip coupled to an end of the shank opposite from the drive portion. The tip includes a compressive residual stress layer formed by blasting to increase a wear resistance of the tip relative to the shank. The tip additionally includes a second maximum outer dimension. The reduced outer diameter of the shank is smaller than the first maximum outer dimension of the drive portion and the second maximum outer dimension of the tip.

A solid state tool system includes a first solid state tool, a second solid state tool, and a third solid state tool. In a first mode, the first solid state tool, the second solid state tool, and the third solid state tool are coupled to one another in a storage configuration. In a second mode, the first solid state tool is used as a tool by itself. In a third mode, the second solid state tool is used as a tool by itself. In a fourth mode, the third solid state tool is used as a tool by itself. In a fifth mode, the first solid state tool is coupled to the third solid state tool and used as a first combination tool. In a sixth mode, the second solid state tool is coupled to the third solid state tool and used as a second combination tool.

A screw bit body allows for efficient torque force application onto a socket fastener. The screw bit body includes a plurality of laterally-bracing sidewalls, a plurality of intermittent sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a first bracing surface, a second bracing surface, and an engagement cavity. The engagement cavity creates an additional gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the screw bit body from the first base to the second base.

A tool bit includes a drive portion configured to be selectively coupled to a tool. The drive portion is composed of a first material. The tool bit includes a working end portion having a shape configured to correspond with a recess of a fastener for the working end portion to engage and drive the fastener. The working end portion includes a first segment and a second segment. The first segment is located between the second segment and the drive portion. The first segment is composed of the first material. The second segment is fixed to the first segment at a connection interface. The second segment is composed of a second material different than the first material.
