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.

Exemplary embodiments are disclosed of backup tools. In an exemplary embodiment, a backup tool generally includes a socket configured for receiving a nut of a flanged connection; a release nut; and an arm extending generally between the socket and the release nut. The arm defines a reaction surface configured to abut against at least a portion of the flanged connection for holding the nut against rotation when a bolt or another nut on a stud is being rotated relative to the nut within the socket of the backup tool, to thereby tighten the flanged connection.

A novel drum speed key tool that provides improved balance and efficiency for the installation, tightening, and removal of drum lug nuts. The drum speed key tool provides a finger receiving cup to allow a user to insert a finger or grip with their hand and efficiently apply rotational force to the drum speed key while maintaining attached to the drum lug nut with reduced slippage of the drum speed key tool from both the user's grip and the drum lug nut.

The multi-function tool described herein includes a case, a drive ratchet installed in the case, a threading die held within the case, a file attached to the case such that a working surface of the file is exposed, a wrench tool removably secured to the case by a wrench retaining feature formed in the case, socket tools removably secured to the case by socket retaining features formed in the case, and a bar extension tool removably secured to the case by a bar extension retaining feature formed in the case. The ratchet has a fitting exposed at the top of the case, and a toggle switch exposed at the bottom of the case. The bar extension tool is compatible with the socket tools, the fitting of the ratchet is compatible with the socket tools, and the fitting of the ratchet is compatible with the bar extension tool.

A socket spanner insert releases or fastens wheel bolts which in the mounted state rest inside wheel bolt holes of a car rim. The socket spanner insert includes a base body which has a screw head receptacle and a tool receptacle, and a sleeve which encompasses the base body at least in portions and is rotatably connected to the base body. In order to prevent damage to the rims when mounting and removing wheel bolts, a retaining element is provided which, during release or fastening of the wheel bolt, blocks a relative rotational movement of the sleeve with respect to the car rim and allows a rotation of the base body within the sleeve.

Provided is a gear box removable electrically driven torque wrench. The gear box removable electrically driven torque wrench includes: a body casing 10 including a body part 12 in which an electric motor and a motor driver are mounted in an internal accommodation space and a handle part 14 extending downward of the body part; a gear box 20 dynamically coupled to a motor rotation shaft 13 of the electric motor in front of the body part 12, and adding and reducing an output according to driving of the electric motor and transmitting the added and reduced output to a tightening member; and an adapter socket including a coupling adapter installed on a gear box coupled surface 11 in front of the body part 12 and a coupling socket fixedly installed on a body coupled surface 21 at the rear of the gear box 20 and detachably coupled to the coupling adapter.

An electrically isolated coupler includes a drive body, a driven body, and a torque transfer assembly. The drive body is made of first metallic material and has a drive end configured to interface with a fastening component. The drive body includes a first interface portion and the driven body includes a second interface portion. The driven body is made of a second metallic material and has a driven end configured to interface with a driving tool. The torque transfer assembly is disposed between the drive body and the driven body to electrically isolate the drive body and the driven body from each other and transfer torque between the drive body and the driven body. The torque transfer assembly includes non-conductive material configured to maintain separation between the drive body and the driven body of at least about 0.400″.
