Stanley-Proto has added 68 new large-drive impact sockets to their already extensive socket line to total nearly 1,750 sockets, 213 of which are strictly large-drive. The line extension encompasses an entire line of metric sockets for the 1-1/2"-drive line, a complete line of 2-1/2"-drive fractional sockets and new fractional sockets for the 1-1/2"-drive line. All Proto impact sockets feature:
A high-performance design that permits them to contact fasteners away from their corners, while spreading stress over a larger area to allow you to apply 15 percent more torque to the fastener, reduce the risk of fastener rounding, and facilitate the turning of worn or rounded fasteners.
The TORQUEPLUS wrenching system.
Special alloy steel, which is heat-treated for the correct balance of strength and hardness.
1-piece construction to ensure concentricity.
Optimal socket wall thickness to provide maximum strength and ample access to restricted fasteners.
