UNF 1" HSS Button Die - TO SUIT A 1' DIE STOCK

UNF 1" HSS Button Die - TO SUIT A 1' DIE STOCKUNF 1" HSS Button Die TO SUIT A 1' DIE STOCK HSS Circular Split Button Die HSS Button Dies (also known as Adjustable Dies) are designed for cutting external threads. They are used for threading rods, bolts, and studs, either by hand using a die stock, or by machine using a floating die holder. They also can be used to cut smaller or larger, than factory setting, by utilising the adjusting screws in the die holder. Dies are manufactured with a thread

• HSS Circular Split Button Die
• HSS Button Dies (also known as Adjustable Dies) are designed for cutting external threads.
• They are used for threading rods, bolts, and studs, either by hand using a die stock, or by machine using a floating die holder.
• They also can be used to cut smaller or larger, than factory setting, by utilising the adjusting screws in the die holder.
• Dies are manufactured with a thread chamfer to aid starting.
• M2-HSS material provides increased wear resistance and superior thread accuracy.
• Unified National Fine (UNF) thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
• The thread profile of UNF is the same as for metric threads and is described in the JIS B0206 standard.
• The thread is described by its major diameter and the number of threads per inch of length (TPI).
• When used on external threads this series has greater tensile stress area than coarse threads of the same size.
• Fine series threads will resist stripping out better than coarse threads in areas where the external and mating internal threads are subjected to loads equal to or greater than the capacity of the screw or bolt.
• Fine threads are also used where the length of engagement is limited 1-1/4 or where wall thickness demands a fine pitch.
