Heavy Hexagon Bolt A325/A325M – Structural Strength You Can Rely On

Heavy Hexagon Bolt A325/A325M, as a classified structural fastener, is one of those structures designed for applications that could not compromise their requirements for strength, stability, and durability. According to the ASTM A325 standards, this bolt has served as the backbone of structural steel connections in:

1. Bridges

2. Towers

3. Oil & gas plants

4. Heavy industrial construction sites across the UAE and GCC

It has a wider head hex than a standard bolt, allowing the heavy A325 hex bolt to resist torque better as well as distribute load better—hence, making it most suitable for critical joints that must be secured against extreme stress, vibration, and exposure to the environment.

Applications & Industry Use

These bolts are widely used in:

1. Steel construction buildings and fabrication

2. Assembly of infrastructure and bridges

3. Installations in oil, gas, and offshore rigs

4. Power plants, wind farms, and solar projects

5. Industrial machinery and equipment fastening

They are the most preferred for contractors, engineers, and procurement teams across Dubai and Abu Dhabi, through Sharjah, Ajman, and the rest of the Middle East, where structural reliability is urgently needed.

Construction & Coating Alternatives

At Global Fasteners, we supply A325/A325M heavy hex bolts in many different materials and finishes, which suit use in harsh and demanding environments. Options include:

1. Plain black finish for general use

2. Zinc-plated for light corrosion resistance

3. Hot-dip galvanized for applications in marine, outdoor, and chemically exposed environments

4. Custom coatings available on request

Heavy hex nuts and hardened washers match these bolts in terms of construction, and together they ensure complete structural integrity and international standards compliance.

Performance & Quality

Every A325 bolt supplied is built to withstand:

1. Very high tensile and shear strength

2. Excellent corrosion resistance

3. Reliable torque locking for vibration protection

4. Conformity to ASTM, ISO, and EN standards
