This 14 x 16mm Draper Expert HI-TORQ double ring ratchet half moon spanner 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 along with the S-shape means these spanners are ideal for use where there’s limited space, and the curved shape makes it easier to reach round obstacles. The ring ends are 12-point Draper Expert HI-TORQ to give a superior grip; with 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.
