A radial screw connecting device for an electrical wire includes a casing, a connecting seat, a press member and a bolt. The casing provides at least an opening for being extended with a joint. The connecting seat is disposed at and attached to a side of the casing and provides a lock hole and a receiving part. The press member is received in the receiving part and provides a pair of inner arms and an inner chamber. The bolt passes through the lock hole and provides a head, a first threaded part, a hollow part and a second threaded part with the second threaded part being engaged in the inner chamber. While in assembling, a ground wire is inserted into the receiving part below the press member and the ground wire can be fixed in the connecting seat and keeps contact with the connecting seat evenly by way of the bolt being turned and pressing a force against the press member and the press member can be lifted along with the bolt during the bolt being turned inversely.
