This comprehensive 12 piece flexible head ratchet combination spanner set from draper expert provides professional grade performance in confined spaces. Manufactured from hardened and tempered chrome vanadium steel with black electroplating, these metric spanners deliver superior corrosion resistance and long term durability for demanding workshop environments.
