These Draper HI-TORQ® metric extra-long double ring ratchet and fixed end spanners are forged from chrome vanadium steel that is hardened, tempered, fully polished and mirror chrome plated for corrosion protection. The extra length provides better access to hard-to-reach spaces, while the 90-tooth ratchet mechanism gives 4° movement enabling use in tight spaces. Both ring ends are 12-point HI-TORQ®, which delivers maximum leverage by transferring torque to the flats and prevents slipping or damage to the fastener.
