A good fastener order is not finished when production is finished.

Before these Dacromet-coated fasteners are ready for shipment, we check key dimensions one by one and make sure the packing is suitable for international transportation.

🔩 Dimensional inspection
📏 Key size verification
📦 Neutral carton packing
🛠️ Reinforced pallet protection

For overseas buyers, the important thing is not only finding the right fasteners — it is receiving the right specifications, properly checked and properly packed.

This is part of what FASNA does in Yongnian: coordinating fastener sourcing, inspection, packing and export delivery for international buyers.

Large fasteners are not standard shelf products.

For industrial fabrication and project applications, bolt diameter, length, grade and production accuracy all need to match the actual drawings and working conditions.

At FASNA Fasteners, we manufacture large-diameter and extra-long bolts for steel structures, industrial equipment, energy and infrastructure projects.

Core production range:
M16–M64 | Length 80–1000 mm
Custom sizes are available according to drawings.

🏭 No filters. No effects. Just real manufacturing.

Take a closer look inside our hot forging workshop and hear the authentic sounds behind every heavy-duty bolt we produce.

From raw material to finished product, quality is built into every step.
# # # Heavy-Duty Hot Forged Bolts for Critical Structural Applications

When standard bolts fail under extreme loads, project delays, safety risks, and costly maintenance become major concerns.

Our hot forging production line is specially designed for manufacturing heavy-duty bolts with superior strength, excellent toughness, and reliable performance under demanding conditions. Through advanced hot forging technology, the bolt grain structure is optimized, providing higher load-bearing capacity and better resistance to impact, vibration, and fatigue.

**Customer Problems We Solve:**
✓ Bolt bending or breaking under heavy loads
✓ Inconsistent quality from different suppliers
✓ Delayed projects due to long lead times
✓ Corrosion and reduced service life in harsh environments
✓ Limited availability of large-diameter and custom-size fasteners

**Typical Applications:**
• Wind Power Towers
• Steel Structure Construction
• Bridges & Infrastructure Projects
• Oil & Gas Pipelines
• Mining Equipment
• Heavy Machinery Manufacturing
• Power Plants & Industrial Facilities

With strict quality control, advanced heat treatment, and comprehensive testing, we ensure every heavy-duty bolt delivers the strength, reliability, and safety your project demands.

Quality Assurance for 10.9 Grade Bolts

Our 10.9 grade bolts are manufactured from high-quality 40Cr alloy steel and undergo precise quenching and tempering heat treatment.

Each production batch is tested using a Rockwell Hardness Tester to ensure the hardness meets the requirements of international standards. Strict hardness control guarantees excellent tensile strength, wear resistance, and service life.

By monitoring hardness throughout production, we effectively prevent common quality issues such as insufficient strength, brittle fracture, and thread damage, ensuring reliable performance in demanding applications such as steel structures, machinery, construction, and industrial projects.

Every batch is traceable and can be supplied with inspection reports upon request, giving customers confidence in product consistency and quality
