About this item:
- 1/4" x 20 BSW 1.5" Chrome Button Die
- British Standard Whitworth (BSW).

- Chrome alloy dies are not suitable for creating precision, safety or critical threads.
- The BSW thread form was developed by Sir Joseph Whitworth in 1841.
- The thread form has rounded roots and crests and is specified in BS84:1956.
