Snap-on's 1/2" Triple Square Socket Drivers offer improved access in servicing VW Touaregs, Audis, and Detroit Diesel 900 and 4000 engines. The new socket drivers have no pins, which translates to a solid shaft in helping to eliminate bit wiggle and tool breakage. Applications can include front axle bolts, differential mounting bolts, transmission plugs, belly pans and caliper bolts.
