This 11 x 13mm 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 and the curved shape makes it easier to reach round obstacles, making the spanner ideal for use where theres limited space. 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.Features & Benefits:Manufactured from hardened and tempered chrome vanadium steel, with a mirror chrome plate finish for corrosion protectionThe 100-tooth ratchet enables 3.6° movement and the curved shape makes it easier to reach round obstacles, making the spanner ideal for use where theres limited spac
