BSF | British Standard Fine 1.5" Chrome Button Die

About this item:
  • Crafted from durable chrome alloy, these split circular button dies are designed for use with a die stock handle.
  • Ideal for both chasing existing threads and creating new male threads on non-ferrous metals and plastics.
  • Engineered with the British Standard Fine (BSF) thread form, which offers a finer pitch than the British Standard Whitworth (BSW) for enhanced thread engagement.
  • Introduced in 1908 and specified in BS84:1956, the BSF thread form provides greater tensile stress area on external threads compared to coarse threads of the same size.
  • Fine threads resist stripping better under high load conditions and are well-suited for applications with limited engagement length or thin wall thicknesses.
  • Please note, chrome alloy dies are not recommended for precision, safety-critical, or high-accuracy threading tasks.
