Installation Procedure

1. Clean both the threaded hole and the screw threads to remove any debris or contaminants. 2. Apply a light coat of anti-seize compound to the threads if recommended for the specific application environment to prevent galling. 3. Thread the cap screw into the mating component by hand to ensure proper engagement and prevent cross-threading.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the screw, leading to thread stripping or fastener failure.Refer to torque specifications for Titanium Grade 5 fasteners of this size and material, and use a calibrated torque wrench.
Using incompatible tools that can damage the hex head.Use a properly sized, high-quality hex socket (Allen key) that fits snugly to ensure even torque distribution and prevent cam-out.

Common Applications

  • Aerospace structural components
  • High-performance automotive assemblies
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Titanium can gall if not properly lubricated or installed with care, especially under high torque or in oxygen-rich environments.
  • Ensure compatibility with mating materials; galvanic corrosion can occur if dissimilar metals are directly coupled in a corrosive electrolyte.
