The Joker combination ratchet spanner is a real revolution in wrench technology. The incredibly versatile open end is now the favourite end to use first. Patented designs allow simple assembly / disassembly; double hex drive design that means no need for flipping over after each turn, fastener holding feature, stop plate, huge torque transfer capability and serrated teeth for turning even rusted bolts or nuts. Ideal as a pipe union wrench, with a strong and ultra fine 80 tooth ring ratchet end. Imperial version marked with silver plate at open end (metric is black). Supplied in a rugged roll up pouch.
