Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this Grade 5 hex head screw delivers critical performance where vibration resistance and structural integrity are paramount. The 7/16"-20 UNF fine threading provides superior holding power in materials prone to stress relaxation, while the zinc plated steel construction offers essential corrosion protection in manufacturing, construction, and machinery assembly environments. The external hex drive design ensures reliable torque transmission during installation, preventing stripping and maintaining clamp load integrity. With full threading along the entire 2" length, this fastener distributes stress evenly, making it ideal for critical joints in structural frameworks, heavy equipment, and automotive assemblies where failure is not an option.

Specification Summary & Compliance
