A slogging wrench (10) comprising: a ring socket (36) for receiving a nut or a bolt head (NBH, NBH′); an elongate body (20) for receiving blows from a mass to transmit torque to the ring socket; and a tool-free locking mechanism (22,24,26,26′,28,30) for retaining a nut or a bolt head in the ring socket. The locking mechanism comprises a slider (22) operable to engage a nut or a bolt head in the ring socket; a channel (24) for guiding movement of the slider towards and away from the ring socket; and an actuator (30,74) manually operable to move the slider with respect to the ring socket. The channel (24) opens into the ring socket (36) via an internal periphery (40) of the ring socket. The locking mechanism comprises a resilient member (34) biasing the slider (22) towards a nut or a bolt head (NBH, NBH′) in the ring socket (36).
