Features and Benefits
Hex socket drive types have a hex-shaped recess in the head and are driven with hex keys or hex socket bits. The driving surface is protected from external damage and provides six sides of contact surface for added torque.
Alloy steel is the strongest of all steel types and offers excellent resistance to wear, fatigue and galling. Nylon is a lightweight, nonconductive material used on threads to prevent loosening.
