A screwdriver bit assembly includes a magnetic ring mounted in a front end of a sleeve hole of a sleeve. A retaining ring is made of a material more rigid than the sleeve, is mounted in the sleeve hole, and is located behind the magnetic ring. A screwdriver bit includes an insertion end, an extending section behind the insertion end, a flange section behind the extending section, and a clamping section behind the flange section. The front end of the screwdriver bit extends through the sleeve hole of the sleeve, the retaining ring, and the magnetic ring. The insertion end extends beyond the sleeve and is located in front of a front end face of the sleeve. The flange section abuts the retaining ring. The clamping section is held by a holding device mounted on the sleeve, providing a holding force towards a longitudinal axis of the sleeve hole.

Some embodiments of the present disclosure include a tool configured to attach to a handle, the tool being multifunctional. The tool may include a housing having a closed end and an open end, the open end defining a cavity sized to accommodate a handle; and a tool end extending from the closed end of the housing, wherein the tool end includes at least one scraper, a nail puller, and a screwdriver.

The invention includes a bit for use in a tool or drill for removal and re-installation of a screw knob necessary to secure a removable or convertible top to a vehicle. This invention replaces the previous methods of screwing and unscrewing screw knobs by hand.

A driving tool includes a coupling component defining a compartment and a driving component received by the compartment. The compartment includes a first receiving section and a second receiving section. The driving component includes a first driving body portion, a second driving body portion, and a connecting portion. The connecting portion is inserted through the first receiving section and is fixedly disposed in the second receiving section. The connecting portion and the second receiving section are forced into a tight interference fit with each other. The second driving body portion includes a length inserted and disposed in the first receiving section. The first and second driving body portions are made to have a first hardness and the connecting portion is made to have a second a second hardness respectively. The second hardness is less than the first hardness.

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.

An automatically opening tool with sliding scale release, including a frame; a tool; a release mechanism attached to the tool; a biasing mechanism for extending the tool; and a scale coupled to the frame and release mechanism. The tool is constructed such that sliding the scale along the longitudinal axis automatically unlocks the tool from the extended or retracted configurations. The tool can open automatically or manually. The tool can swing open or extend out a front opening in the frame.

A hand tool includes a handle and a driving head. The handle includes a first driving recess, a second driving recess disposed opposite to the first driving recess, a body made of a first material, and a cover member mounted around an outer surface of the body and made of a second material different from the first material. The handle further includes a first receiving recess therein. The driving head includes a connection portion alternatively engaged into one of the first driving recess and the second driving recess to provide a stationary connection between the handle and the driving head.

A method of installing a light fixture base to a surface is disclosed that employs an elongated tool that engages a mounting screw in rough alignment with an axis of the elongated member. The mounting screw and elongated tool are inserted through a mounting hole in the base and moved upward through thermal insulation in the base. The elongated tool is then manipulated while viewing both a tip end of the mounting screw and a threaded hole in a mounting bracket attached to a junction box so as to attach the mounting screw to the mounting bracket. The elongated tool then serves as a guide while sliding the base upward along the elongated tool so as to rapidly attach the base to a mounting screw in the mounting bracket.

A driver tool for insertion and removal of a first part configured for threaded engagement in a corresponding threaded bore in a second part has a driving end portion of polygonal shape with multiple flats configured for engagement in a recess in the first part having a corresponding polygonal shape. Some or all of the flats have a respective grabbing feature or edge designed to grab or grip into the opposing surface of the recess to allow a greater amount of torque to be applied to the first part when the tool is rotated in the unthreading direction than when it is rotated in the opposite threading or insertion direction.
