Key Features & Benefits at a Glance
- Exceptional tensile strength of 150,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black phosphate steel coating extends service life in harsh industrial environments.
- High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity over repeated use.
- Flanged head design eliminates the need for separate washers, simplifying installation and distributing load more effectively.
- Coarse UNC threads with Class 2A fit allow for quick assembly and better tolerance to debris in rugged conditions.
- Full threading offers consistent grip along the entire length, enhancing holding power in demanding setups.
- External hex drive enables easy tightening with standard tools, speeding up maintenance and reducing labor time.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 8 hex head screw addresses critical challenges in construction, machinery, and automotive sectors where vibration and high loads are common. The black phosphate steel material combats rust and corrosion, ideal for outdoor or humid settings, while the UNC coarse thread and Class 2A fit ensure secure fastening even in dirty or high-vibration environments. Its flanged feature provides a larger bearing surface, preventing loosening and reducing point stress on assembled components. By integrating high tensile strength and durability, it minimizes downtime and maintenance costs, making it a reliable choice for engineers seeking long-term performance in structural and equipment fastening.
Specification Summary & Compliance
This screw adheres to precise Class 2A thread fit and UNC coarse spacing standards, ensuring dimensional accuracy for consistent assembly. It meets SAE J429 specifications for Grade 8 fasteners, confirming high mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricts hazardous substances, supporting sustainable industrial practices.
