Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the titanium screw, which can lead to thread galling or stripping.Always use a calibrated torque wrench and adhere to recommended torque specifications for Grade 5 Titanium, which are generally lower than for steel.
Using incompatible tooling, potentially damaging the hex head of the screw.Ensure the hex socket wrench or driver precisely fits the 8mm head width of the cap screw to prevent cam-out and damage.

Common Applications

  • Aerospace structural components
  • Medical implants and devices
  • High-performance automotive assemblies
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Titanium can be susceptible to galling; proper lubrication and care during installation are crucial.
  • Ensure compatibility of mating materials to prevent galvanic corrosion, especially in marine or chemical environments.
