A4-80 grade stainless steel - identical corrosion resistance to A4-70 but with a higher tensile strength equivalent to that of 8.8 high tensile steel.

Brass - offers an attractive, corrosion resistant finish.

High tensile carbon steel with a bright zinc plated finish - the general purpose non-stainess grade for screws and bolts where good corrosion resistance is not required.

High tensile carbon steel with a bright zinc plated finish - the general purpose non-stainess grade for washers where good corrosion resistance is not required.
