Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the fastener, leading to thread stripping or material fatigue.Always use a calibrated torque wrench and adhere to recommended torque specifications for Titanium Grade 5 fasteners.
Using incompatible washers or mating materials that can cause galvanic corrosion.Utilize washers made of compatible materials, such as titanium or appropriate plastics, to prevent galvanic corrosion when fastening titanium.

Common Applications

  • Aerospace structural components
  • Marine hardware and fittings
  • High-performance automotive assemblies

⚠️ Engineering Warnings

  • Titanium Grade 5 can gall if not properly lubricated or if overtightened.
  • Ensure proper torque control to avoid damage to the fastener or mating components.
