Key Features & Benefits at a Glance
- Exceptional corrosion resistance with hot-dipped galvanized steel coating, ideal for outdoor and harsh industrial environments.
- Superior tensile strength of 120,000 psi ensures reliable performance in high-stress structural and construction applications.
- High hardness rating (Rockwell C19) provides excellent wear resistance and durability under heavy loads.
- Coarse UNC thread design (3/4"-10) allows for faster installation and better grip in various materials.
- Class 2A thread fit ensures smooth assembly and consistent performance with standard nuts.
- External hex drive and hex head design offers secure, high-torque tightening with common tools.
- Full threading along the 1 1/2" length maximizes engagement and clamping force across the entire fastener.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade A325 hex head screw delivers robust performance in structural steel connections, bridge construction, and machinery assembly. The hot-dipped galvanized steel material provides a thick, durable barrier against rust and corrosion, extending service life in exposed or humid conditions. With a coarse UNC thread and Class 2A fit, it ensures quick, reliable installation without cross-threading, reducing labor time and maintenance costs. The fully threaded design and 120,000 psi tensile strength offer consistent load distribution and high resistance to vibration loosening, making it a trusted choice for critical construction and engineering projects.
Specification Summary & Compliance
This screw features a 3/4"-10 UNC coarse thread with Class 2A thread fit for precise dimensional accuracy. It complies with ASME B18.2.6, ASTM A325, and ASTM F3125 manufacturing standards, ensuring consistent quality and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable usage.
