Product Description

This high-strength hex heavy bolt is made from carbon steel grade 12.9, offering exceptional tensile strength for structural support in critical applications. The M16 size with a 7/16-inch thread is engineered for large structural projects including steel structures, bridges, and high-load equipment. The black oxide finish provides enhanced corrosion resistance and a professional appearance.

Designed for industrial, mechanical, and structural applications, this bolt delivers heavy-duty performance and long-term reliability in demanding environments.

Applications

12.9 grade screws are manufactured using SCM435 alloy steel with minimum tensile strength of 1220Mpa and hardness of 39~44HRC. These ultra-high strength fasteners are primarily used in:

Textile industry equipment
Hydraulic systems
Injection molding machinery
Industrial machinery components

As the top-grade screw variety, 12.9 level fasteners offer exceptional hardness and tensile strength, making them ideal for special industrial applications with high performance requirements.
