Snap-on introduces Flank Drive Xtra socket system

Snap-on has released its new Flank Drive Xtra (FDX) socket system. The first redesigned Snap-on socket since the patented flank drive system was developed in 1965, the FDX offers more turning power, a more secure fastener engagement and greater efficiency, the company states.

“Snap-on has taken its genius, often imitated flank drive design and completely reimagined a new, improved socket that delivers even better performance than before,” says Brian Benes, a Snap-on Tools product manager.

According to the company, FDX features include:

  • An improved design that grips fasteners further off the corners. The FDX offers up to 25 percent more strength than flank drive sockets.
  • With its angled contour, the socket wall grips damaged fasteners more closely for 50 percent more turning power.
  • A chamfered lip on both the hex and drive ends of the socket allows for a better grip and more turning power, especially for shallow-headed fasteners and fasteners with limited top clearance.
  • FDX sockets feature grooved, grippable outer walls, a design feature that makes them easier to remove.
  • Easier identification and improved readability are both achieved through large, distinctive markings on the socket exterior.
