Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the screw, which can strip threads or damage the mating component.Always use a calibrated torque wrench and adhere to the specified torque values for the fastener and the application.
Using improper tools that can round the hex head, making removal difficult.Employ high-quality, properly sized hex wrenches or sockets for secure engagement and optimal force transfer.

Common Applications

  • Aerospace structural components
  • Medical implants and surgical instruments
  • Marine hardware and offshore equipment

⚠️ Engineering Warnings

  • Titanium Grade 5 exhibits excellent galling resistance, but proper lubrication (anti-seize) is still recommended for critical applications, especially with aluminum or titanium mating materials, to prevent thread seizure.
  • Always verify compatibility of Titanium Grade 5 with other materials in the assembly to prevent galvanic corrosion, although it is generally highly resistant.
