The draper hi torq 12 piece flexible head ratchet combination spanner set is a professional metric spanner set designed for automotive, mechanical and engineering applications. Each spanner is forged from chrome vanadium steel that has been hardened, tempered and mirror chrome plated for long lasting corrosion protection and durability. The standout feature of this combination spanner set is the 180° flexible head ring end, which incorporates a 90 tooth ratchet mechanism. This fine tooth mechanism allows just 4° movement between clicks, making it ideal for working in confined spaces where a full swing isn't possible. The open end is offset at 15° to improve knuckle clearance and access around obstructions. The 12 point hi torq® ring end design delivers optimal leverage by transferring torque to the flats of fasteners rather than the corners, preventing slipping and reducing the risk of rounding off bolt heads. This 12 piece set covers all the popular metric sizes from 8mm to 19mm, supplied on a convenient plastic storage rack for workshop organisation.
