Professional Applications & Engineering Value

These Grade 2 Titanium Socket Head Cap Screws with 4-40 UNC coarse threads solve critical engineering challenges in demanding applications. The titanium material provides exceptional corrosion resistance while maintaining high strength-to-weight ratio, making them perfect for aerospace, marine, and chemical processing equipment. The standard socket head profile with 3/32" hex drive ensures reliable torque transmission without stripping, while the Class 2A thread fit prevents cross-threading during assembly. These fully threaded screws deliver consistent clamping force across the entire 3/8" length, eliminating the need for multiple fastener types in precision assemblies and reducing inventory complexity.

Specification Summary & Compliance
