Description:
Automotive High-Strength Bolts are made from alloy steels such as SCM435, SCM440, and 42CrMo, offering superior tensile strength and high preload capacity for secure, reliable connections. With strict dimensional tolerances for threads and heads, along with multi-phosphate and chromium-free coating treatments, they provide excellent fastening performance and durability in demanding automotive applications.
