S-94081A718 5/16"-18 x 3 1/2" Titanium Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional strength-to-weight ratio from Grade 5 Titanium construction, providing robust performance without adding unnecessary bulk to assemblies
• Superior corrosion resistance inherent to titanium material, ensuring long-term reliability in harsh industrial environments
• High tensile strength of 130,000 psi delivers reliable clamping force and resistance to mechanical failure under extreme loads
• Rockwell C36 hardness maintains thread integrity and prevents stripping during repeated installation and removal cycles
• External hex drive design allows for high-torque installation with standard tools, reducing assembly time and improving efficiency
• UNC coarse threading with Class 2A fit ensures quick engagement and reliable fastening in various materials
• Partial threading configuration provides optimal grip length while minimizing unnecessary thread contact

Professional Applications & Engineering Value

Engineered for demanding industrial applications where both strength and corrosion resistance are critical, these Grade 5 Titanium hex head screws deliver exceptional performance in aerospace, marine, chemical processing, and high-temperature environments. The 5/16"-18 UNC coarse thread design ensures rapid assembly and disassembly while maintaining secure fastening in vibration-prone applications. The external hex drive accommodates high torque requirements, making them ideal for maintenance operations and structural assemblies. With their partially threaded configuration, these screws provide precise clamping force distribution while reducing the risk of cross-threading. The combination of titanium's natural corrosion resistance and the 130,000 psi tensile strength makes these fasteners suitable for applications where stainless steel alternatives may not provide sufficient strength or weight savings.

Specification Summary & Compliance

These hex head screws feature precise Class 2A thread fit with UNC coarse threading (5/16"-18) and right-hand thread direction. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications. Dimensional specifications include 3 1/2" length with 7/8" minimum thread length, 1/2" head width, and 13/64" head height for standardized tool compatibility.
