Installation is convenient and efficient: The design adopts a twist-shear type, during installation, only a dedicated electric wrench is needed to break the flower head to complete the preload control. No additional torque detection is required, significantly improving construction efficiency and reducing labor costs.
Connection is highly reliable: Through pre-tension to achieve frictional connection, it has excellent anti-slip performance, can effectively resist vibration, impact and alternating loads, avoiding connection loosening, and ensuring the long-term safety and stability of the structure.
Weather-resistant and corrosion-resistant durable: Various surface treatment options such as hot-dip galvanizing and Dacromet are provided. It can be used in humid and corrosive environments for a long time, significantly extending the product's service life and reducing maintenance frequency.
Precision control is precise: Strictly following national standards for production, the cooperation accuracy of bolts, nuts and washers is high, and the preload consistency is good, ensuring that the mechanical performance of each connection pair is stable and meets the standards.

Structural Design: The tail of the round-head shear bolt is equipped with a rose-head. By breaking the rose-head, the pre-tightening force can be intuitively confirmed to reach the design value. The installation process is visualized and traceable.
Material Properties: High-strength alloy steel is selected, and after quenching and tempering treatment, its tensile strength and yield strength exceed those of ordinary bolts. It can withstand heavy loads and is suitable for heavy-load structural scenarios.
Specification Compatibility: Multiple diameter specifications (such as M16, M20, M22, M24, etc.) and length options are provided, which can match different thickness steel structure components and meet diverse engineering requirements.
Appearance Differentiation: Available colors include black oxide, silver-gray hot-dip galvanizing, etc. This not only meets the anti-corrosion requirements but also facilitates the specification identification and management at the engineering site.

Building steel structure: Widely used in the connection of beams and columns in high-rise office buildings, large venues, industrial plants, etc. of steel structure buildings, it is a key fastening component of the core load-bearing nodes.
Bridge engineering: Suitable for the connection of steel box girders and steel truss girders of highway bridges and railway bridges. It can withstand alternating loads such as vehicle passage and wind force, ensuring the safety of the bridge structure.
Power and communication towers: Used for the component connection of transmission towers and communication base station towers. It can maintain stable connection even under extreme conditions such as strong winds and earthquakes.
Mechanical and lifting equipment: Applied to the connection of steel structures of large-scale construction machinery and lifting equipment, bearing high-intensity vibration and impact, ensuring the reliable operation of the equipment.
Rail transportation: Serves the track support steel structure and vehicle body connection of subways and high-speed railways, meeting the strict requirements of high reliability and long lifespan for rail transportation.
