Heavy-duty: HDA Truck Pride announces leadership expansion
Snap-on has introduced its new Flank Drive Xtra (FDX) socket system, a redesigned and updated version of Snap-on’s original Flank Drive system, which was first introduced in 1965.
According to the company, the benefits of the FDX include the following:
- With an improved design that grips fasteners further off the corners, the FDX offers up to 25% more strength than Flank Drive sockets.
- With its angled contour, the socket wall grips damaged fasteners more closely for 50% more turning power.
- An optimally 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, which makes them easier to remove.
- Easier identification and improved readability are both achieved through large, distinctive markings on the socket exterior.
