Teng Tools 8512A spanner wrench

12 piece metric combination spanner set featuring a brand new design that provides an anti slip grip on the open end as well as the hip grip function where the spanner drives on the flank of the fastening rather than the corner. These two design features combine to provide a much better grip with less risk of damage to the fastening. The design also provides grip on fastenings with worn or rounded corners. Supplied in a handy fold out storage case with a magnetic fixing.
