Products Show

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.

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.

Other low price import pull stud’s are machined by a turning process, but our pull studs are fully ground by CNC on all critical surfaces including a pilotunder the flange of retention knob for full contact between tool holder's taper end and retention knob. Precision grinding pull stubs have higher surface finish and dimension accuracy. The fitting accuracy is obviously higher than that of machine pull stubs, effectively reduces the error of machine tool and cooperation, so as to improve the accuracy and stability of the connection and improves the precision of the machine tools and lengthens the service life.
