Steel, ferrosoferric oxide coating or electroless nickel plated.
For use when securing linear guideway rails or similar. The eccentricity of the clamping screw is formed as a result of the central axis of the head being offset from the central axis of the shank. This offset ensures that the rail is firmly clamped by the head when the screw is tightened. The torx socket drive ensures the screw can withstand a high tightening torque.
Use following suffixes to specify material when ordering:
BL - ferrosoferric oxide coating
EN - electroless nickel plated, providing good corrosion resistance.
