- Made of high quality alloy steel,has higher wear resistance and better toughness.
- Precision grinding pull stubs have higher surface finish and dimension accuracy.
- Precision finished on the bottom of the flange to improve fitting with the bottom nose of the taper on the tool holder.
- Each pull Stud Retention Knob come with a transparent plastic case for storage.
Using high quality alloy steel 20CrMnTi forging, the material is metallographic dense, uniform and stable. After carburizing, the outside of material is hardened, and the inside of material is still soft and has enough toughness. Therefore, Material has higher wear resistance and better toughness.
High quality black oxide finish can ensure long pull stub life and a non-rusting surface. The following picture shows the pull stub after black oxide finish
Other low price import pull stud are made from 45 medium carbon steel , but our pull stud is made from fine alloy steel, 20CrMnTi with heat treatment to HRC 56-58, better performance than 45 medium carbon steel. The price for 20CrMnTi is double of 45 medium carbon steel. After the forging process, the raw material can maintain the mechanical performance and flow line. This will ensure the life and stability of the material, after the material has been run through several heat treatment processes.
