Carbon steel anchor bolts are heavy-duty fastening components designed to secure steel structures, machinery, and equipment to concrete foundations. They are widely used in structural anchoring applications where high load-bearing capacity, pull-out resistance, and long-term stability are required. Common configurations include L-type, J-type, straight type, and custom-bent anchor bolts to suit different foundation designs and installation conditions.

ZSD Screw specialize in high-strength carbon steel anchor bolts designed for demanding structural and industrial use. By integrating raw material selection, cutting, bending, thread rolling, heat treatment, and surface finishing within an in-house production system, ZSD Screw maintains full control over product quality and dimensional accuracy. This integrated manufacturing capability allows ZSD Screw to deliver reliable, international-standard anchor bolt solutions directly to global customers, ensuring stable mechanical performance and long-term structural safety.

Standard anchor bolt dimensions are manufactured according to DIN, ISO and ASTM standards.Custom drawings and samples are accepted.

Strength Grades:  Anchor bolts are available in different strength grades to meet various load requirements: 4.8, 8.8, 10.9, 12.9, 14.9. ASTM grades: ASTM F1554 Gr.36, Gr.55, Gr.105 (where specified by project requirements). Heat treatment is completed in-house to ensure stable mechanical properties, controlled yield strength, and reliable tensile performance under long-term structural loading.

Surface Treatment:  To improve corrosion resistance and service life, we offer the following surface finishes: Zinc plated (blue / white / yellow). Black oxide. Hot dip galvanized. Zinc flake coating. Phosphate. Dacromet. Special surface treatments are available according to customer requirements, especially for outdoor and infrastructure applications.

Applications:  In mechanical equipment manufacturing, ZSD Screw carbon steel anchor bolts are widely used for fixing heavy machinery, compressors, pumps, production lines, and automated equipment bases to concrete foundations. These applications require high anchoring force, stable preload, and resistance to vibration to ensure safe and continuous operation of industrial equipment.

In electronic equipment and industrial electronics, carbon steel anchor bolts are applied in securing control cabinet platforms, equipment frames, testing system bases, and industrial enclosure foundations. Reliable anchoring performance helps maintain alignment accuracy, vibration resistance, and long-term structural stability in precision industrial environments.

In the new energy sector, carbon steel anchor bolts from ZSD Screw are used in solar mounting foundations, photovoltaic support structures, wind turbine base systems, inverter platforms, and energy storage equipment foundations. These applications demand stable load-bearing performance and long-term durability under outdoor exposure, temperature variation, and continuous mechanical stress. Controlled surface treatment improves corrosion resistance and service life in renewable energy installations.

In conventional and renewable power generation facilities, these bolts are applied in generator foundations, turbine bases, auxiliary equipment supports, cooling system structures, and pipeline anchoring systems. Secure anchoring performance is essential for maintaining structural stability under high static loads, thermal expansion, and long-term vibration. ZSD Screw provides anchoring solutions that support safe installation and reliable operation in thermal power plants, wind power projects, hydropower stations, and energy infrastructure facilities.

In the automotive and transportation industries, ZSD Screw carbon steel anchor bolts are used for fixing production line equipment, robotic systems, heavy assembly machinery, and structural columns within manufacturing plants and logistics facilities. Consistent strength performance and dimensional accuracy support stable equipment positioning and production safety in high-load industrial environments.

In heavy industry and engineering equipment manufacturing, these bolts are widely applied in steel structure foundations, construction machinery bases, mining equipment installations, lifting system supports, and large-scale industrial infrastructure projects. Applications involving heavy static loads and impact forces require dependable anchoring strength and long-term reliability. ZSD Screw supplies anchor bolts designed to support structural integrity and safe operation in demanding industrial conditions.
