The draper hi torq 6 piece double ratchet ring spanner set delivers professional grade performance for mechanics and engineers working in confined spaces. These metric double ring ratchet spanners are forged from chrome vanadium steel that is hardened, tempered, fully polished and mirror chrome plated for corrosion protection. Each spanner features a 90 tooth ratchet mechanism on both ring ends, requiring just 4° of movement to engage the next tooth. This minimal swing arc makes these spanners ideal for working around obstructions where conventional spanners cannot complete a full rotation, such as engine bays or tight pipework installations. The 12 point hi torq® design transfers torque to the flats of fasteners rather than the corners, maximising leverage whilst preventing slipping or damage to bolt heads and nuts. This makes the set particularly suitable for working with corroded or precision fasteners where maintaining grip is critical.
