BORDO INTERNATIONAL PTY LTD Bordo 1/2" x 20 UNF 1.5" Chrome Button Die

Bordo 1/2” x 20 UNF 1.5” Chrome Button Die

The Bordo 1/2” x 20 UNF Chrome Button Die is designed for producing or restoring fine-pitch Unified National Fine (UNF) external threads. Manufactured from durable chrome alloy, this die is ideal for general workshop use, thread maintenance, and applications requiring strong, high-tensile thread engagement.

UNF threads feature a finer pitch than UNC, providing increased tensile stress area and excellent resistance to stripping under load. Suitable for use with a die stock handle, this die can be used for chasing damaged threads or forming new threads on softer metals and plastics.
