BORDO INTERNATIONAL PTY LTD Bordo 1" x 11 BSPF 2" Chrome Button Die

The Bordo 1” x 11 BSPF 2” Chrome Button Die is designed for forming, restoring, and repairing British Standard Pipe Parallel (BSPF) external threads. These split circular button dies are ideal for use with a die stock handle and are commonly chosen for maintenance, repair, and general-purpose threading tasks on non-ferrous metals and plastics.
Key Features:

• Thread Standard: BSPF (British Standard Pipe Parallel), widely used for mechanical coupling and non-pressure sealing applications.
• Versatile Use:
  • Suitable for chasing and cleaning worn or damaged threads.
  • Capable of cutting new external threads where precision and sealing integrity are not critical.
• Material: Chrome alloy, offering durability for general workshop use (not intended for precision, structural, or critical thread production).
• Thread Form Details:
  • Standard BSPF threads typically have a 55o thread angle, though some US-influenced variations may use 60o.
  • BSPF belongs to the G-Series pipe thread standard and is specified under JIS and ISO R228.
  • Designed primarily for mechanical fastening rather than pressure sealing.

Technical Specifications:

• Diameter (inch): 1
• Pitch (TPI): 11
• Thread Form: BSPF

Applications:
BSPF button dies are widely used in plumbing maintenance, equipment repair, industrial machinery servicing, and fabrication work where parallel pipe threads are required for fittings, couplings, and mechanical assemblies. Their large, stable thread profile makes them suitable for producing reliable non-tapered pipe threads in workshop and field environments.
