This BSW hex nut, manufactured to BS 1083, is made from bright steel—steel with no coating or surface treatment. While the material is strong, it offers little inherent protection against corrosion on its own. The nut has a Grade A strength rating and features British Standard Whitworth threading. Whitworth threads (BSW/BSF) are not recommended for international use; for new builds, we suggest going with metric threads (M/MF/MEF) or Unified threads (UNC/UNF) instead. Please note that dimensions may vary slightly depending on availability.
