Anti Slip Metric Combination Spanner Set in Tool Roll 8512MM

12 piece metric combination spanner set featuring a typically Teng new design in combination spanners that gives an anti slip grip on the open end as well as the Teng Tools hip grip function where the spanner drives on the flank of the fastening rather than the corner, two design features that combine to give a much better grip with much less risk of damage to the fastening. The design also gives grip on fastenings with worn or rounded corners. Supplied in a handy tool roll.
