The Bordo 1/2" x 20 UNF 1" Chrome Button Die is part of Bordo’s professional threading tool range, engineered for reliable fine-pitch thread cutting and repair in workshop, fabrication and maintenance applications. Designed for tradespeople and technicians, this button die delivers clean, consistent external threading performance on Unified National Fine (UNF) fasteners and components where access is limited or confined.
Manufactured from high-quality chrome alloy with a bright finish, this button die utilises the Unified National Fine (UNF) thread form — a 60° fine-pitch standard widely adopted in mechanical and industrial assemblies. Chrome alloy construction offers corrosion resistance and durability for everyday threading tasks. The 1/2" diameter with 20 threads per inch (TPI) makes this tool ideal for creating or cleaning external threads on non-ferrous metals and plastics when a full die cannot be used due to space constraints. Button dies are commonly used with a die stock handle to chase worn threads or form new male threads.
Bordo is recognised for producing dependable threading solutions backed by quality manufacturing standards. Industrial Shed ensures fast access to trusted trade-grade button dies when you need them on site or in the workshop.
