The handle also has a coupling end formed of spaced parallel arms with a slot therebetween with aligned apertures through the arms. An intermediate portion is formed between the gripping end and coupling end. The wrench has a head in a generally cylindrical configuration having a lower end formed of a cylindrical wall with an upstanding recess for the receipt of a locknut, with a plurality of downwardly extending legs for removable coupling with respect to a locknut to be turned.
