Proxxon Industrial ROTARY 23082 Forward/reverse ratchet 1/4 (6.3 mm) 180 mm

No space for leverage? That's not a problem for the rotary ratchet. By turning the handle, you can preload one side to the stop. You need just a few millimetres to loosen and screw down. Simply turning the handle is sufficient when "idling".
