Draper 27744 8231FBSMM Hi Torq® Metric Flexible Head Double Ring Ratchet Spanner, 8 X 9mm

These Draper HI-TORQ® metric flexible head ratchet combination spanners are forged from chrome vanadium steel that is hardened, tempered, fully polished and mirror chrome plated for corrosion protection.
Both ring ends have a 180° flex head and 90-tooth ratchet mechanism, and the 4° movement enables use in tight spaces.
The 12-point HI-TORQ® delivers maximum leverage by transferring torque to the flats and preventing slipping or damage to the fastener.
