Critical: Box spanners = LOW TORQUE applications. For high-torque use socket + ratchet. Tommy bar leverage = limited. Don't replace with pliers or improvised tools — damages soft fastener. Brands: Maxigear, Sutton Tools. Companion: spanners, sockets, hand tools.
Box spanners (also called tubular spanners or basin wrenches) are hollow tube wrenches with a hex socket pressed into each end, driven by a tommy bar that passes through holes in the tube. They reach hex fasteners and nuts in recessed positions a normal spanner or socket can't — the classic case is the back-nut on a basin or sink tap, often buried behind splashbacks and inside cupboards.
Common uses
- Plumbing — tap connections, basin and bath waste nuts, toilet cistern fixings.
- Spark plug removal where a dedicated plug socket won't fit.
- Long-reach work into deep recesses on machinery and equipment.
Buy sized to the fasteners you actually meet. For plumbing, the workshop standard kit covers the common imperial and metric sizes you'll find on Australian taps and waste fittings.
