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 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 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 bracing surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base. The engagement cavity is specifically positioned offset from the first lateral edge by a first distance.

A connecting tool for connecting a first connecting portion and a second connecting portion of at least one connecting member. The connecting tool may include a shaft. The shaft may include a shaft axis, an operational end, and a body. The shaft may include a recess configured to engage said first connecting portion of said at least one connecting member. The operational end may include an aperture configured to engage said second connecting portion of said at least one connecting member.

A fastener extractor tool is an apparatus that is used to remove a seized or damaged fastener. The apparatus may include at least one shank body and at least one torque-tool body. The at least one shank body allows the apparatus to be attached to an external torque tool. The torque-tool body engages the seized fastener to apply torque to dislodge said seized fastener. The at least one torque-tool body may include a plurality of laterally-bracing sidewalls and at least one engagement feature. The plurality of laterally-bracing sidewalls engage with the seized fastener to efficiently transfer torque from the external torque tool to the seized fastener. The at least one engagement feature is an engagement cavity that forms at least one engagement tooth on the at least one torque-tool body. The at least one engagement tooth engages the seized fastener to ensure torque is transferred to the seized fastener.

The present invention relates to a technical field of a tool glove combining with various tools, more particularly to a tool glove applied for construction, civil engineering, outdoor sport, agriculture, forestry, butchery, catering, fishery, husbandry or horticulture. In addition, the tool glove of the present invention can combine with various replaceable toolheads upon working demand, such as building repair, high scaffold assembly/disassembly, hitting work, mountain climbing sport, tree climbing for picking fruit, meat cutting in butchery, peeling and vegetable-fruit cutting in catering, scales removing and fish-shrimp cutting in fishery or husbandry, boring for growing flower in horticulture, earthmoving, painting by using brush or roller in painting works, so that it is not necessary for a user to carry multiple dedicated tools to complete various works.

An apparatus for holding interchangeable tool bits includes a body including inner walls defining first and second bit holding spaces configured to receive first and second interchangeable tool bits, a resiliently deformable bit holder coupled to the body and separating the first and second bit holding spaces, the first bit holding space adjacent to and encircled by an inner surface region of the resiliently deformable bit holder and the second bit holding space adjacent to an outer surface region of the resiliently deformable bit holder, such that the inner surface region and the outer surface region of the resiliently deformable bit holder are configured to deform against the first and second interchangeable tool bits respectively, to hold the first and second interchangeable tool bits when the first and second interchangeable tool bits are in the first and second bit holding spaces. Other apparatuses and systems are disclosed.

The driver bit according to the present invention includes: a tip on which a cross blade is formed; a torque transmitting part having a polygonal outer circumference; and a locking groove which extends in the circumferential direction between the tip and the torque transmitting part and into which locking balls enter, wherein the tip has four blade forming grooves forming the cross blade, the blade forming grooves are continuous with the locking groove, and the blade forming grooves are arranged so that the blade forming grooves have bottom parts, at which they are connected with the locking groove, located inwardly of the outer circumference of the torque transmitting part, and the center lines are displaced from a line connecting the shaft center with vertex positions of the polygonal outer circumference and a line connecting the shaft center with center positions of sides of the polygonal outer circumference.

A mold, punch and workpiece are provided. In a preferred embodiment, a tapering outer edge is provided, along with a plurality of rib sets arranged circumferentially about the outer edge, and a ramp. A ramp may be located to facilitate the removal of burrs. Various slot patterns may be provided or formed, including star-shapes/Torx® slots. Using the present invention, a driver bit may be more securely fit to the slot of a screw, for example, allowing the screw to be threaded into a machined part more securely and smoothly, reducing rocking, shaking or tilt.

An apparatus, system, and method are disclosed. The apparatus includes a body coupled to a head, the head including a hole of at least three sides and a shaft of at least three sides, the shaft being disposed inside the hole. The system includes a fastener apparatus that includes a head including a hole of at least three sides and a shaft of at least three sides located inside the hole. The system further includes a fastener driver that includes a driver head of at least three sides, and a driver hole of at least three sides, the driver hole located within the head. The method includes providing a fastener apparatus that includes a body coupled to a head, the head including a hole of at least three sides and a shaft of three sides that is located within the hole. The method further includes using the fastener apparatus.

A universal multiple bit adapter is disclosed. The adapter is designed for compatibility with most of the available screws in the construction market including Philip screw, Roberson screw, Torx screw and nut drivers. The multiple bit adapter comprises a cylindrical enclosed housing chamber with plurality of openings to enable selective application of the elongated driver bits. The screw driver bits are made from hardened steel and housing chamber is made from any metal or plastic material. The multi-functional bit adapter unit further comprises a clip protection member to hold the elongated driver bits from rotating further during short repair maintenance. This convenient single unit is small, compact and easy to carry in a pocket and can be easily attached to a power tool like a drill or impact wrench.

A tool handle for holding multiple tools of different sizes during use. A wedge and body which, when placed together, creates a handle with a generally cylindrical shape and internal cavities for retaining hexagonal wrenches. A sliding wedge holds the hexagonal wrench and itself into place. A plurality of slots that allow each size tool to be indexed to the underside of the sliding member/wedge. There are two grouping arrangement of tools within the handle: a large group and a small group facing the opposite direction. The purpose for the two groups is to optimize the function of the wedge. If all of the tools were oriented in the same main slot then the smallest tools would not protrude from the end of the handle/body in a screwdriver mode to facilitate good function. Therefore the two groupings are arranged back to back to stabilize the tools laterally.
