Abstract

Apparatus for tightening or loosening fasteners pneumatically, electrically, hydraulically and manually driven are disclosed, and in one example includes: a receiving member (111), rotatably supported in the apparatus for tightening or loosening, for receiving the fastener; a device (100) for effecting rotation of the receiving member to tighten or loosen the fastener, and an apparatus (150) which transfers a reaction force during tightening or loosening of the fasteners. The apparatus which transfers a reaction force includes: a first force-transmitting element (160) rotatably attachable about a turning force axis of the device for effecting rotation, and a second force-transmitting element (170) either rotatably attachable about extensibly and retractably attachable along, or rotatably attachable about and extensibly and retractably attachable along at least a portion of the first element.
