Our high-strength bolts and nuts are engineered for exceptional performance in demanding industrial applications. With a temperature range of -40°C to 150°C and hardness rating of HRC≥50, these durable fasteners provide reliable performance under the most challenging conditions.
These high-strength bolts and nuts are essential components across multiple industries including heavy machinery assembly, structural engineering, automotive, construction equipment, and mining operations. The coach bolt style is particularly useful in wooden structures, fencing, and panel assembly where a smooth, rounded head prevents damage or snagging.
Customization Options
We offer extensive customization including ISO 3506 A4-80 stainless steel bolts and nuts (SS316), ISO 898-1 class 8.8 high tensile bolts and nuts, and EN 14399-1 HV 10.9 preloaded structural bolting assemblies. All products are RoHS compliant and available in sizes from M20 to M45.
Support & Services
Our technical team provides expert support for product selection, compatibility, and installation procedures. We offer comprehensive after-sales services including warranty support and product replacement for manufacturing defects. Regular maintenance recommendations include checking proper torque and corrosion resistance for optimal performance and safety.
All bolts and nuts undergo 100% inspection to ensure dimensional accuracy, mechanical properties, and compliance with industry standards.
