Features and Benefits

Button head types have cylindrical heads with curved tops and flat bearing surfaces. They slightly protrude out of the workpiece and are used for aesthetic purposes.
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.
