This 12-piece Draper Expert HI-TORQ® metric reversible ratchet combination spanner set is manufactured from hardened and tempered chrome vanadium steel, with a mirror chrome plate finish for corrosion protection. The 100-tooth ratchet enables 3.6° movement and the open end is set at 15°, making the spanners ideal for use where theres limited space. The ring end is 12-point , providing a superior grip; with Draper Expert HI-TORQ®, the spanners grip 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. The set comes supplied in a useful storage/carry rack.
