## Long description

Hartsson 17A318Z is a 1/2" drive 18 mm hex socket bit engineered for secure engagement with hex-head bolts and nuts.

Advantages
The 18 mm hex profile provides accurate contact with fasteners to reduce wear on bolt heads. Built for use with 1/2" drives, the socket bit supports common ratchets and torque tools, enabling controlled torque application.
