BSW | BRITISH STANDARD WHITWORTH DIE NUT

About this item:

  • Manufactured to British Standard Whitworth (BSW) specifications, these chrome alloy die nuts are designed for reliable threading performance.
  • Ideal for applications where button dies are unsuitable due to limited workspace or on-site thread accessibility.
  • Function effectively as thread chasers to clean and restore existing threads, ensuring smooth assembly and maintenance.
  • Capable of creating new male threads on non-ferrous metals and plastics, offering versatility across various materials.
  • Constructed from chrome alloy, these dies provide durability but are not intended for producing precision, safety-critical, or high-tolerance threads.
  • The BSW thread form, developed by Sir Joseph Whitworth in 1841, features rounded roots and crests, conforming to BS84:1956 standards.
  • Characterized by a 55° thread angle, distinguishing it from the 60° angle found in Metric and Unified thread systems.
