This 8mm Draper Expert HI-TORQ® metric flexible head ratchet combination spanner is manufactured from hardened and tempered chrome vanadium steel, with black electroplating for corrosion protection. The 100-tooth ratchet enables 3.6° movement and with a 180° flexible head and the open end set at 15°, these spanners are ideal for use where there’s limited space. The ring end is 12-point Draper Expert HI-TORQ®, providing a superior grip; with Draper Draper Expert HI-TORQ®, the spanner grips the flats of the fastener rather than the corners. This gives more grip while transmitting more torque to the nut or bolt and prevents damage to the corners by spreading the load across the flats.
