Melco TM20 TM20 Metric Box Spanner 20 x 22mm x 125mm (5in) MELTM20

Double ended box spanners are thinner than a socket and are much longer so that they can be used to loosen or tighten bolts and nuts in narrow recesses, meaning that they are often used in plumbing maintenance and automotive repair. This tubular box spanner is made from bright plated steel and able to accommodate a tommy bar. Size 20 x 22mm Length 125mm (5 in)
