Installation Procedure

1. Ensure mating threads are clean and free of debris. 2. Apply a small amount of anti-seize compound suitable for titanium if required by the application environment. 3. Hand-thread the screw to engage initial threads, then use a calibrated torque wrench to tighten to the specified torque value for the application, avoiding over-tightening.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, which can strip threads or compromise material integrity.Always use a calibrated torque wrench and adhere to recommended torque specifications for the application and material.
Using incompatible lubricants or thread compounds that can cause galvanic corrosion or galling with titanium.Consult material compatibility charts and use only approved anti-seize compounds specifically designed for titanium fasteners.

Common Applications

  • Aerospace structural components
  • Medical implants and surgical instruments
  • High-performance automotive and motorsport assemblies
  • Marine hardware and offshore equipment

⚠️ Engineering Warnings

  • Titanium can gall under high pressure and friction; proper lubrication and installation torque are crucial.
  • Avoid using steel tools that can contaminate the titanium surface, leading to potential corrosion.
