BORDO INTERNATIONAL PTY LTD Bordo 3/4" x 16 UNF Chrome Alloy Die Nut

Bordo chrome alloy die nuts are ideal for restoring or forming external UNF threads, especially where a full-size button die cannot be used due to restricted access or on-site thread repair conditions. Suitable for general engineering, automotive, and maintenance applications.

The UNF thread form was introduced in 1948 as part of a standardisation effort across the USA, Canada, and the UK. Featuring a finer pitch than UNC, the UNF series provides a greater tensile stress area and improved resistance to thread stripping. This makes UNF threading well-suited to applications requiring strength, precision, or limited thread engagement.

Key Features & Benefits

• Repairs, restores, or forms external UNF threads
• Compact die nut design for tight or restricted work areas
• Durable chrome alloy construction for long service life
• Suitable for use on non-ferrous metals and plastics
• Fine thread improves tensile strength and load distribution
• Not intended for certified precision or safety-critical thread production

Technical Specifications
