Applications

• HSS Button Dies (also known as Adjustable Dies) are designed for cutting external threads
• They also can be used to cut smaller or larger, than factory setting, by utilising the adjusting screws in the die holder
• Fine threads are also used where the length of engagement is limited 1-1/4 or where wall thickness demands a fine pitch
