An A2 stainless steel full hex BSW (British Standard Whitworth) nut is a standard, six-sided, internally threaded fastener made from A2 (AISI 304) stainless steel, designed to fit the specific BSW thread profile. Its purpose is to create a strong, durable, and corrosion-resistant mechanical joint. Due to the decline of the BSW standard, these nuts are primarily used for maintenance, repair, and restoration of legacy machinery and heritage projects, as well as general outdoor use where the BSW standard is still relevant.
