1. Each pull stud is tested throughly which ensures the quality of the pull stud.

2. Made from fine alloy steel 20CrMnTi with treatment to 54-57 HRC.

3. Hard outside and soft inside, with higher wear resistance and better toughness.

4. Surface coating processing treatment, improve surface hardness and endurance, cleaness better, antirust, accuracy more stable.

5. Precision turning on all critical surface.

6. Cryogenic treatment and thermal aging treatment can reduce the inner residual stress, improve durability and precision stability.

7. Appearance electroless plating process improve surface hardness durability, cleanness, precision stability, the surface is more smooth, anti-rust and anti-corrosion is better, feel comfortable and surface is more nice.
