Grey Pneumatic 2116S 1/2" Drive M16 12-Point Socket

1/2" Drive M16 Impact Socket

The Grey Pneumatic 2116S is a 1/2 inch drive metric impact socket sized for M16 fasteners. Its 12-point configuration allows engagement at multiple angles, useful in tight clearance. The socket is built for pneumatic and electric impact tools. It suits professional technicians and serious DIYers working on suspension, wheel hubs or heavy equipment.

12-Point Geometry Under Load

The twelve-point broaching distributes torque across more contact faces than a six-point design, reducing the chance of rounding off stubborn or corroded M16 nuts. The black oxide finish resists corrosion and helps identify the socket in a busy tray. Impact-rated steel withstands repeated hammer blows without cracking. It maintains fit through extended service intervals.

Replaces Worn or Shallow Sockets

This socket upgrades from worn 12-point or six-point equivalents that slip on damaged flats. It also replaces shallow sockets when extra reach is needed for recessed bolts. The jump is worth it when the previous socket rounds fasteners or cannot clear the thread length. Buyers who need a different drive size or a non-metric hex should look elsewhere.
