- High hardness rating of Rockwell C35 provides superior resistance to wear and deformation, extending service life in demanding conditions.
- Coarse UNC threading offers quicker assembly and better resistance to vibration loosening compared to fine threads.
- Partially threaded design allows for precise clamping force control, ideal for applications requiring specific grip lengths.
- External hex drive enables easy installation and removal with standard tools, improving maintenance efficiency.
- ASTM A193 compliance guarantees material quality and manufacturing consistency for critical high-temperature and high-pressure services.
- Class 2A thread fit ensures smooth assembly with standard nuts while maintaining sufficient clearance for easy installation.
Professional Applications & Engineering Value
This ASTM Grade B7 hex head screw is engineered to address critical challenges in high-stress environments such as pressure vessels, valve assemblies, and structural supports. The steel construction combined with 125,000 PSI tensile strength and Rockwell C35 hardness provides exceptional resistance to mechanical stress and thermal cycling. The 1/2"-13 UNC coarse thread design ensures rapid installation and superior vibration resistance, while the partially threaded configuration allows optimal load distribution across the 4 3/4" grip length. These features make it indispensable for industrial applications requiring reliable, high-strength fasteners that maintain integrity under extreme operating conditions.
Specification Summary & Compliance
This hex head screw features precise 1/2"-13 UNC coarse threading with Class 2A thread fit for consistent assembly performance. Manufacturing and material specifications strictly adhere to ASTM A193 standards, ensuring compliance with industry requirements for high-strength Grade B7 fasteners. The product meets common regulatory and industry standards for heavy-duty industrial use, providing assurance of quality and reliability in critical applications.
