A tool includes a first output from a gear system, the first output along a first axis and a second output from the gear system, the second output along a second axis. A first torque limiter is attached to the first output along the first axis and a second torque limiter is attached to the second output along the second axis. A first tool bit is attached to the first torque limiter along the first axis and a second tool bit attached to the second torque limiter along the second axis.

A hook spanner has a spanner body having two opposite side surfaces, a handle segment, and a hooking segment formed on an end of the handle segment. The hooking segment has an abutting end surface located away from the handle segment and having an abutting end surface extending obliquely from one of the two opposite side surfaces of the spanner body to the other side surface. The hook spanner is adapted to turn a nut having multiple grooves arranged around the nut. Each groove has an inclined surface extending obliquely and inwardly from a peripheral surface of the nut. The abutting end surface is aligned with the inclined groove surface of one of the grooves of the nut to stably turn the nut.

Drum hardware tools are described. Some implementations may include a tension rod hardware tool designed for assembling/installing/setting up and/or disassembling/uninstalling tension rods. Some implementations may include a drum wing nut hardware tool designed for assembling/installing/setting up and/or disassembling/uninstalling drum hardware wing nuts.

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 self-clamping torque adapter comprises a tool base, a central hub, a plurality of clamps, and a cam actuator mechanism. The tool base has a central axis and the central hub is rotatably coupled to the tool base and configured to rotate relative to the tool base about the central axis. The central hub comprises a torque input member configured to receive a torque input. The plurality of clamps are slidably coupled to the tool base, and configured to displace bi-directionally along a radial axis. The cam actuator mechanism couples each of the plurality of clamps to the central hub. Rotation of the central hub relative to the tool base causes the cam actuator mechanism to move each of the plurality of clamps in a radial direction.

A multipurpose tool for handles and valves has been designed to facilitate the operation of outdoor water faucets (sillcocks, cocks, spigots, bibs, taps) and water splitters (diverters, wyes). Metal fingers (pins, tines) on the tool fit into or onto window, tee, and cross tee handles to open or close water faucets. Other metal fingers fit onto various shapes of levers to open or close water splitter valves. The valve fingers also work as a wrench to tighten or loosen the nut securing most faucet handles to the spigot. Both types of fingers can be used to scoop out damaged leaky washers. The tool arm has a metal file surface to smooth rough faucet edges that touch washers, often a place where water leaks occur. Finally, the hollow tool handle contains extra plumbing sealing tape and washers for onsite faucet and hose repairs.
