• High tensile strength of 80,000 psi ensures reliable performance under heavy loads, preventing fastener failure.
• External hex drive and hex head design allows for easy installation and high torque application with standard tools.
• Class 2A thread fit and UNC coarse thread provide faster assembly and greater tolerance to minor damage and debris.
• Partial threading offers an unthreaded shank for precise clamping and shear strength in specific applications.
• Compliance with ASME B18.2.1 guarantees dimensional consistency and interchangeability for engineering projects.
• Rockwell B70 hardness provides excellent durability and resistance to wear over extended use.

Professional Applications & Engineering Value

This 7/16"-14 UNC hex head screw is engineered to solve critical challenges in industrial assembly and construction. The 18-8 Stainless Steel material offers outstanding corrosion resistance, making it suitable for outdoor, marine, and chemical-exposed environments where rust can compromise structural integrity. The coarse UNC thread and partial threading design enhance vibration resistance and provide a strong grip in materials like steel and heavy timber, reducing the risk of loosening. With an external hex drive, it allows for quick, high-torque installations, streamlining production lines and maintenance workflows. This industrial-grade fastener is ideal for machinery, structural frames, and heavy equipment where 80,000 psi tensile strength and reliable performance are non-negotiable.
