Stanley 6-point 1/2′ Drive Deep Well Impact Socket – 18mm
Stanley® sockets feature our Max-Drive design, a unique radius corner design which provides 15% more torque, making it easy to tighten fasteners and simplifies the turning of rounded corners. Helps reduce fastener wear without contact on the outer 5% of the fastener, so fasteners last longer. Helps reduce slipping on frozen or rusted fasteners. These impact sockets are made of alloy steel for strength and durability, then heat treated to balance strength and hardness. The socket wall thickness is optimized to provide strength while retaining ample access to restricted fasteners.
