BORDO INTERNATIONAL PTY LTD Bordo 9/16" x 18 UNF Chrome Alloy Die Nut

This 9/16” x 18 UNF Chrome Alloy Die Nut is designed for restoring, repairing, and forming Unified National Fine (UNF) external threads, particularly in confined spaces where a standard button die cannot be used. Ideal for field maintenance, machinery servicing, and general-purpose thread repair, die nuts provide a practical solution for thread restoration and light thread cutting on a variety of materials.
Key Features:

• Thread Standard: Unified National Fine (UNF), offering a finer pitch than UNC for improved thread engagement and strength.
• Versatile Use:
  • Excellent for chasing and cleaning damaged or worn threads.
  • Capable of cutting new male threads on non-ferrous metals and plastics.
• Material: Manufactured from durable chrome alloy, suitable for general-purpose threading but not intended for precision, structural, or critical applications.
• Thread Form Details:
  • UNF standard introduced in 1948 to unify thread systems across the USA, Canada, and the UK.
  • Same 60o thread profile as metric threads, specified under JIS B0206.
  • Finer threads provide greater tensile stress area compared to coarse threads of the same diameter.
  • Improved resistance to thread stripping under high load conditions.
  • Ideal for applications with limited engagement length or where a fine pitch is required due to wall thickness constraints.

Technical Specifications:

• Diameter (inch): 9/16
• Pitch (TPI): 18
• Thread Form: UNF

Applications:
UNF die nuts are commonly used in automotive repair, machinery maintenance, engineering workshops, and equipment restoration. Their fine-thread geometry offers strong engagement, improved load distribution, and excellent resistance to stripping-making them suitable for precision mechanical assemblies and high-performance applications.
