Redesigned Flank Drive Xtra

Snap-on Tools has given the first redesign to it Flank Drive Xtra (FDX) socket system. Introduced in 1965, greater turning power, improved secure fastening engagement and greater efficiency are all part of the redesign. The FDX system grips fasteners futher off the corners, giving up to 25 per cent more strength. It can grip rounded corner, damaged fasteners. Its shape has also been upgraded, now with a chamfered lip on the hex and drive ends to give more grip and turning power. The sockets have a grooved, grippable outer walls to make them easier to remove. Large and distinctive markings also make it easier to identify and read the sockets.
