Goliath UNC HSS Left Hand Circular Split Button Die

• HSS Left Hand 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 the 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.
• The Unified National Coarse thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
• The thread profile of UNC 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).
• This thread series is commonly used in the mass production of bolts, screws, and nuts.
• It is used for threading into lower tensile strength materials (bronze, brass, aluminium and plastics) to obtain the best resistance to stripping of the internal thread.
• It is also used on quick assembly or disassembly or if corrosion or slight damage is possible.
