The sealey premier 13 piece extra long double ring ratchet spanner set is a comprehensive collection of metric spanners engineered for professional mechanics and technicians. Manufactured from hardened and tempered chrome vanadium steel with a fully polished mirror finish, this set combines durability with corrosion resistance for long-term workshop use. Each spanner features 12-point ratchet and fixed walldrive ring ends, with a 72-tooth ratchet mechanism that requires only 5 rotation to pick up the next tooth. This minimal swing arc makes the set particularly effective in confined spaces where standard spanners cannot achieve a full rotation. The walldrive system grips fastener walls rather than corners, delivering up to 30% more torque whilst reducing the risk of rounding off bolt heads. The extra long design, ranging from 230mm to 445mm in length, provides extended reach for recessed fasteners and improved leverage on stubborn fixings. This set is ideal for automotive work, machinery maintenance, and any applications requiring access to deeply seated nuts and bolts. The comprehensive metric sizing from 8mm through to 24mm covers the most commonly used fastener dimensions in professional environments.
