Description
Structural principle
Core features:
High-strength materials: Made of alloy structural steels such as 35CrMo and 42CrMo, after quenching and tempering treatment, the tensile strength is ≥800MPa (such as grade 10.9, grade 12.9), suitable for heavy-load and high-vibration scenarios.
Flange design: The bolt head is equipped with a circular flange (with a diameter of 1.5 to 2 times the nominal diameter), which increases the contact area, distributes pressure, and prevents the connected parts from deforming.
Surface treatment: Commonly used anti-corrosion processes such as hot-dip galvanizing and Dacromet are adopted, with a zinc coating thickness of ≥85μm, featuring both high strength and corrosion resistance.
