The main spanner accessory is the extender bar which grips the shaft of a spanner and extends the length of the shaft. A longer shaft means a greater leverage so the spanner can exert a greater force on the fastener. Extender bars can easily snap cheap spanners so be careful.
Accessories are also available to help keep your spanners ordered and accessible.
Pouches and holders that attach to belts are an excellent way of keeping a spanner on your person between uses…
…as are tool aprons which can hold a number of different tools without pulling your trousers down!
Tool boxes and tool rolls can be purchased to store a spanner set in so you always know where to find the right size…
…and spanner rings can hold a set like a bunch of keys so they are always together.
