A2-70 grade stainless steel - also known as grade 304 or 18/8. A general purpose grade of stainless steel.
A4-70 grade stainless steel - also known as grade 316 or 18/8/3. A higher corrosion resistant, marine grade of stainless steel.
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.
High tensile carbon steel with a bright zinc plated finish - the general purpose non-stainess grade for nuts where good corrosion resistance is not required.
Nylon - a tough lightweight plastic. On offer here to help protect bodywork/panels when assembled with metal fasteners.
