Features and Benefits
Flat head types have flat surfaces that taper toward the screw body to allow for countersinking. The flat head lies flush against the workpiece.
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. It has high tensile strength and offers excellent resistance to wear, fatigue and galling.
