Quantity
The Yancheng Hex Socket Cap Bolt is a high-performance industrial fastener engineered for demanding bolting applications. Manufactured from ASTM A193 B7 alloy steel, this bolt delivers exceptional tensile strength, fatigue resistance, and wear durability – critical properties for pressure vessels, flanges, and heavy machinery. Its hex socket cap design enables precise torque transmission via a standard Allen key, reducing cam-out risk and simplifying installation in confined spaces. Each bolt meets the stringent requirements of ASME B18.3, ensuring dimensional accuracy, thread uniformity, and interchangeability with mating socket cap screws.
Coating & Corrosion Protection
The hot-dip galvanizing coating provides a metallurgically bonded zinc layer that offers superior corrosion resistance – far outperforming electroplated or mechanical zinc finishes. This makes the Yancheng Hex Socket Cap Bolt ideal for outdoor structures, marine environments, chemical plants, and wastewater treatment facilities where moisture, chlorides, or pH fluctuations accelerate rust. The HDG coating also delivers sacrificial protection, extending service life even if the surface is scratched during installation.

Application Scenarios
- Flanged joint assemblies in petrochemical refineries – replacing standard hex heads where clearance is limited.
- Heavy equipment frames – mining crushers, wind turbine towers, and conveyor systems.
- Bridge and highway guardrails – requiring long-term weathering resistance.
- HVAC and plumbing supports – where vibration resistance and maintenance accessibility are priorities.
- Flanged joint assemblies in petrochemical refineries – replacing standard hex heads where clearance is limited.
- Heavy equipment frames – mining crushers, wind turbine towers, and conveyor systems.
- Bridge and highway guardrails – requiring long-term weathering resistance.
- HVAC and plumbing supports – where vibration resistance and maintenance accessibility are priorities.
Performance Advantages
- High preload retention – B7 material minimizes stress relaxation at elevated temperatures (up to 450°C).
- Wear-resistant head – the socket broach maintains its geometry after repeated tightening cycles.
- Gall-resistant threads – HDG coating reduces friction, enabling consistent clamp load with lower torque scatter.
