Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 120,000 PSI tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance through black oxide finish, extending service life in demanding environments
• Optimized thread engagement with UNC coarse threading and Class 2A fit for faster assembly and vibration resistance
• Enhanced durability from Grade 5 steel construction with Rockwell C25 hardness for repeated use
• Secure torque transmission via external hex drive and 3/4" head width for easy installation with standard tools
• Full-threaded design ensuring maximum grip length and uniform stress distribution along the entire 1½" shaft
• Industry compliance meeting ASME B18.2.1 and RoHS 3 standards for quality assurance and environmental safety

Professional Applications & Engineering Value

This Grade 5 steel hex head screw delivers critical performance where structural integrity matters most. The black oxide finish provides essential corrosion protection for outdoor equipment, machinery frames, and construction assemblies exposed to moisture. Its UNC coarse thread pattern prevents cross-threading during high-speed assembly while maintaining grip in vibration-prone applications. The external hex drive design allows for high torque application with common tools, making it ideal for heavy-duty fastening in manufacturing plants, automotive systems, and infrastructure projects. Engineered to withstand sustained mechanical stress, these fully threaded screws ensure uniform clamping force across the entire engagement length, preventing joint failure in critical connections.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with 1/2"-13 UNC coarse thread specifications. Complies with ASME B18.2.1 dimensional standards and SAE J429 material requirements for Grade 5 fasteners. Meets RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances. The right-hand thread direction and standardized dimensions ensure compatibility with existing industrial components and tooling systems.
