These Draper HI-TORQ® metric reversible ratchet combination spanners are forged from chrome vanadium steel that is hardened, tempered, fully polished and mirror chrome plated for corrosion protection. The open end is offset at 15°. The ring end has a 15° cranked head which incorporates a 90-tooth ratchet mechanism allowing 4° movement, enabling use in tight spaces. There is also a forward and reverse direction lever on the ring end. The 12-point HI-TORQ® delivers maximum leverage by transferring torque to the flats and preventing slipping or damage to the fastener. This 12-piece set contains the full range.
