Installation Procedure

1. Ensure mating threads are clean and free from debris or damage. 2. Apply a small amount of appropriate anti-seize compound to the threads if recommended for the specific application. 3. Hand-tighten the screw to seat it, then use a calibrated torque wrench to tighten to the manufacturer's specified torque value for the M15 size in the mating material. 4. Verify proper seating and engagement of all threads.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the screw, which can lead to thread stripping or fastener failure.Always use a calibrated torque wrench and adhere to the recommended torque specifications for the specific application and mating materials.
Using the wrong type of lubricant or anti-seize, which can affect torque values and create galvanic corrosion issues.Consult material compatibility charts and engineering recommendations for appropriate lubricants or anti-seize compounds suitable for Titanium Grade 5.
Cross-threading the screw during installation, leading to damaged threads on both the screw and the mating component.Carefully align the screw with the mating threads and start threading by hand for at least two full turns before using a tool.

Common Applications

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

⚠️ Engineering Warnings

  • Titanium alloys can gall under high pressure and low speed. Use of anti-seize compound is strongly recommended.
  • Ensure compatibility with mating materials to prevent galvanic corrosion, especially in aggressive environments.
