1.1/4″ x 12 UNF 3″ HSS Button Die – Goliath 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.
