The draper hi torq 12 piece reversible ratchet combination spanner set is a professional grade metric spanner set designed for mechanics, engineers and technicians working in confined spaces. Each spanner is forged from chrome vanadium steel that has been hardened, tempered, fully polished and mirror chrome plated for excellent corrosion protection and durability. The ring end features a 15° cranked head incorporating a 90 tooth ratchet mechanism that allows just 4° movement between clicks, making these spanners ideal for working in restricted areas where standard tools cannot operate. A forward and reverse direction lever on the ring end provides quick switching between tightening and loosening operations. The open end is offset at 15° for improved access to recessed fasteners. The 12 point hi torq® design in the ring end delivers optimal leverage by transferring torque to the flats of the fastener rather than the corners, preventing rounding and damage to nuts and bolts. This makes the set particularly suitable for automotive repair, machinery maintenance and assembly work where fastener preservation is important. The complete 12 piece set covers the most commonly used metric sizes from 8mm to 19mm.
