The Bordo 5/16" x 24 UNF 1.5" Chrome Button Die is part of Bordo’s professional threading tool range, designed to cut or chase fine external threads with ease in workshop and on-site environments. Engineered for general threading and thread repair tasks, this chrome-finish button die works with a standard die stock handle — making it ideal for maintenance, fabrication and repair work requiring Unified National Fine (UNF) threads.
Manufactured from chrome alloy in a split circular button design, this die utilises the UNF (Unified National Fine) thread form — a fine-pitch standard introduced in 1948 that delivers greater tensile stress area and improved resistance to thread stripping compared to coarse threads. The 5/16" diameter with 24 threads per inch (TPI) is perfect for creating clean, fine external threads or chasing worn ones on non-ferrous metals like aluminium, brass, bronze and plastics. Note that chrome alloy button dies are designed for general use and not intended for precision, safety-critical or specialised threading applications.
Bordo is a trusted name in industrial threading and cutting tools, backed by quality manufacturing standards. Industrial Shed ensures fast access to dependable trade-grade button dies when you need them on site or in the workshop.
