Made from vanadium special steel, this insulated open-ended spanner will stand the test of time and any job you can throw at it. Vanadium produces a secondary hardening effect within the steel.
The curved ergonomic spanner benefits from a double coating insulating layer, which allows you to see when the coating is damaged. Orange on the outside, the inner insulating layer is yellow.
It meets a range of standards and this size 11 AF fully insulated open-ended spanner is suitable for hexagonal screw heads.
