Milwaukee 49-66-6040 1/4" Drive 6mm Deep Impact Socket

Milwaukee 49-66-6040 SHOCKWAVE Impact Duty 1/4" drive 6mm deep 6-point metric impact socket. One socket, forged from impact steel, for 1/4" drive impact wrenches, impact drivers with an adapter, and ratchets.

• Size markings: stamped and ink-filled, so the size stays readable as the socket wears
• 6-point hex: non-slip geometry that grips the flats to keep sockets and fasteners from rounding
• Forged impact steel: made for high-torque impact use
• Dual hole and ring groove: easier to snap on and pull off the anvil
• Standards: meets ASME standards; part number is laser etched

Is this the right one for you?

Deep sockets reach nuts on long bolts, studs and threaded rod that a standard socket cannot get over. If the bolt does not stick out past the nut, a standard-depth socket keeps the tool closer to the work in tight spots. This is a metric size (6mm); Milwaukee makes this socket in a full run of SAE and metric sizes. It is a 1/4" square drive, so a 1/4" hex impact driver needs a socket adapter. Milwaukee's Lifetime Guarantee covers the socket.
