M4 Series DIN912 Carbon Steel Hex Socket Head Cap Screw.
The hexagon head socket cap screws have a narrow head and are perfect for use in hard to reach areas, particularly in machine repair and maintenance. As this range is produced to 12.9 grade black self-colour high tensile steel, they are ideal when corrosion resistance is not required but a stronger more hardened material than 8.8 and 10.9 great steel is required.
