• Enhanced thread engagement with UNC coarse threading and Class 2A fit, delivering reliable fastening in vibration-prone applications
• Controlled thread distribution through partial threading design, providing optimal grip length where needed
• Regulatory compliance assurance with RoHS 3 and REACH compliance, meeting international environmental standards
• Consistent performance backed by Rockwell C36 hardness rating, maintaining dimensional stability under load

Professional Applications & Engineering Value

These Grade 5 Titanium Hex Head Screws deliver critical performance advantages in demanding industrial settings where weight reduction, corrosion resistance, and high tensile strength are paramount. The 5/16"-18 UNC coarse thread configuration ensures rapid installation and superior resistance to vibration loosening, while the partial threading design provides precise load distribution. Engineered with 130,000 psi tensile strength and Rockwell C36 hardness, these fasteners maintain integrity in aerospace, marine, and chemical processing applications where traditional steel fasteners would succumb to corrosion or weight penalties. The external hex drive with substantial 1/2" head width enables high-torque installation without stripping, making them ideal for maintenance-critical assemblies requiring frequent disassembly.

Specification Summary & Compliance

This 5/16"-18 UNC hex head screw features precise Class 2A thread fit tolerances and coarse thread spacing per unified thread standards. The 2 3/4" length with 7/8" minimum thread length ensures proper engagement depth. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming restriction of hazardous substances. The Grade 5 Titanium material meets industry standards for high-strength titanium fasteners with verified mechanical properties including 130,000 psi tensile strength and Rockwell C36 hardness.
