Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to thread stripping or material fatigue.Always use a torque wrench and adhere to specified torque values to prevent over-stressing the fastener and mating components.
Using incompatible lubricants or thread lockers that may react with titanium.Consult material compatibility charts and use only lubricants or thread lockers specifically recommended for titanium fasteners to avoid galling or embrittlement.

Common Applications

  • Aerospace structural components
  • Medical device implants and instrumentation
  • Marine hardware and offshore equipment
  • High-performance automotive and motorsport
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Titanium can gall under high pressure or low lubrication; use anti-seize and proper torque.
  • Ensure compatibility with mating materials to prevent galvanic corrosion.
