This spanner combines a ratchet end and an open-end spanner in 16 mm, offering two complementary modes of use on the same tool. Its extra-long length allows access to bolts located in restricted or deep spaces, a frequent constraint when working on classic mechanics. It integrates naturally into the tooling of classic vehicle restorers, where accessibility of parts often presents a particular difficulty. A versatile and robust tool for carrying out precise interventions without risk of damaging surrounding elements.
