1.1/2" x 8 BSF 3" HSS Button Die - Goliath

About this item:

• 1.1/2" x 8 BSF 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.
• British Standard Fine thread form was based upon the British Standard Whitworth (BSW) but has a finer thread (more threads per inch for a given diameter).
• The thread form was first introduced in 1908 and is specified in BS84:1956.
• 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 or where wall thickness demands a fine pitch.
