Abstract: Components of a an assembly of operatively related devices for installing a flange cover for a gas valve include a bit especially useful for engaging a corresponding access hole or opening in the face plate portion of a flange cover for transmitting torque thereto for coupling it with a matingly threaded gas valve. The bit end of the bit may have a hole extending axially therethrough and is preferably successively smaller as the end is approached. In one embodiment the bit includes a drive end of a shape differing from the bit end so that a shoulder is formed separating the two ends and providing a stop to prevent the bit from sliding into the hole in which it is engaged. In another embodiment, the drive end is circular with a square recess to accept a drive lug of an appropriate driving tool.

Abstract: A tool for quickly removing or replacing threaded fasteners such as nuts or bolts has a spool-like body with an axial bore. A socket in the bore is dimensioned to engage a fastener. A flexible member can be wrapped around a circumferential channel in the body. A user can loosen or tighten A fastener by wrapping the flexible member around the channel and pulling on a pull ring on the free end of the flexible member. The tool is particularly well adapted to removing or tightening nuts or bolts in constricted spaces such are encountered when repairing automotive engines or other machinery. The tool is simple and inexpensive to manufacture. The tool may be provided in a kit having several tools for turning fasteners of several standard sizes.
