Goliath 1-3/8" x 8 TPI UN 2-1/2" HSS | AIMS Industrial

Product Features

• M2-HSS material provides increased wear resistance and superior thread accuracy
• In almost all thread series, the number of threads per inch decreases as the diameter increases

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
• All the bolts in the 8N series had 8 threads per inch, all in the 12N series had 12 threads per inch (used in boilers and for thin nuts on shafts), and in 16N, sixteen threads per inch (used where precise positioning of a big nut is required e.g., for bearing adjusting nuts)

Specifications

• They are used for threading rods, bolts, and studs, either by hand using a die stock, or by machine using a floating die holder
• The N constant-pitch series were later replaced by the constant-pitch Unified Thread series, which have the Unified thread form and are designated 4-UN, 8-UN, and so on
• HSS Circular Split Button Die
• Dies are manufactured with a thread chamfer to aid starting
