Installation Procedure

1. Clean both the screw threads and the mating tapped hole or nut to remove any debris or contaminants. 2. Apply a small amount of anti-seize compound if specified for the application to prevent galling, especially in titanium-to-titanium connections. 3. Engage the screw by hand to ensure proper thread alignment, then use a calibrated torque wrench set to the appropriate torque value for the material and application to achieve optimal clamping force.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the titanium screw, which can lead to thread stripping or fastener failure.Always use a calibrated torque wrench and adhere to manufacturer-recommended torque specifications, factoring in the unique properties of titanium.
Not using anti-seize compound with titanium fasteners, increasing the risk of galling during installation.Apply a thin, even layer of a suitable anti-seize compound specifically designed for titanium when mating titanium components or in environments prone to corrosion.

Common Applications

  • Aerospace structural components
  • Marine hardware and offshore structures
  • Chemical processing equipment
  • High-performance automotive and motorsport assemblies

⚠️ Engineering Warnings

  • Titanium Grade 5 can gall if not properly lubricated, especially when mating with itself or certain other metals. Always use appropriate anti-seize compounds.
  • Ensure compatibility with mating materials. While titanium offers excellent corrosion resistance, galvanic corrosion can occur with dissimilar metals in certain environments.
